Connecting the Hardware

This section describes how to connect the OnCell G3111/G3151-HSPA cellular IP gateway to a host PC or serial
device for the first time. We cover topics such as: Wiring Requirements, SIM Installation, Wall and DIN-Rail
Mounting, Connecting the Power, Connecting to the Ethernet, Connecting to a Serial Device, Adjustable Pull
High/Low Resistors for the RS-485 Port, and LED Indicators.

Wiring Requirements

ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your device. The OnCell
G3111/G3151-HSPA should be secured at one location.

Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings,
the wiring could overheat, causing serious damage to your equipment.

Temperature Caution!
Be careful when handling the device. When plugged in, the device internal components generate heat, and
consequently the casing may feel hot to the touch.

You should also heed the following guidelines:

• Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
Note: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.

• Use the type of signal transmitted through a wire to determine which wires should be kept separate. The
rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
• Keep input wiring and output wiring separate.
• Where necessary, it is advisable to label the wiring to all devices in the system.

SIM Card Installation

In order to protect the SIM card, the SIM card slot is located inside the OnCell G3111/G3151-HSPA casing. You
will need to unscrew and remove the outer SIM card cover before installing or removing the SIM card.

Follow these steps to remove or install the SIM card:

1. Remove the screw holding the outer SIM card cover.

2. Push the outer SIM card cover down to unlock the SIM
card slot.
3. Rotate it downwards to expose the SIM card slot.
4. (a) Remove the SIM card from the SIM card slot, or
(b) Insert a SIM card into the SIM card slot.
5. Reverse the above steps to replace the outer SIM card
cover.

OnCell G3111/G3151-HSPA Series Getting Started

Device Mounting
There are two ways to mount the OnCell G3111/G3151-HSPA IP gateways – wall
mounting and din-rail mounting.

For wall mount, using the built-in “ears” to attach the device to a wall or the inside of a
cabinet. We suggest using two screws per ear for a more stable attachment. The heads
of the screws should be less than 6.0 mm in diameter, and the shafts should be less
than 3.5 mm in diameter, as shown in the figure at the right.

For din-rail mount, secure both din-rail mounting kits to the “ears”, as shown in the
figure below, and hook it to your din-rail track.

Connecting the Power

Follow the pin assignment figure below and wire the 12 to 48 VDC power to the 3-pin terminal block. If the
power is properly supplied, the “PWR” LED will glow a solid green color to indicate that the system is ready.

Connecting to the Ethernet

Connect one end of the Ethernet cable to the OnCell G3111/G3151-HSPA’s 10/100M Ethernet port and the
other end of the cable to the Ethernet network.

If the cable is properly connected, the OnCell G3111/G3151-HSPA will indicate a valid connection to the
Ethernet as follows:

• The Ethernet LED glows a solid green when connected to a 100 Mbps Ethernet network.
• The Ethernet LED glows a solid orange when connected to a 10 Mbps Ethernet network.
• The Ethernet LED flashes when Ethernet packets are being transmitted or received.

Connecting to a Serial Device

The OnCell G3111-HSPA supports one RS-232 port that connects through a DB9 male connector on the bottom
panel.

The OnCell G3151-HSPA supports one RS-232/RS-422/RS-485-4w/RS-485-2w port that connects through a
DB9 male connector on the bottom panel.

Adjustable Pull High/Low Resistors for the RS-485 Port

(G3151-HSPA)
In long distance transmission or critical environments, you may need to add termination resistors to prevent
the reflection of serial signals. When using termination resistors, it is important to set the pull high/low
resistors correctly so that the electrical signal is not corrupted. Since a particular pull high/low resistor value
cannot fit all environments, the OnCell G3151-HSPA uses DIP switches to set the pull high/low resistor values
for the serial port.

To set the termination resistor to 150 kΩ, make sure both of the assigned DIP switches are in the OFF
position. This is the default setting.

To set the termination resistor to 1 kΩ, make sure both of the assigned DIP switches are in the ON position.

ATTENTION
Do not use the 1 kΩ setting on the OnCell G3151-HSPA when using the RS-232 interface. Doing so will degrade
the RS-232 signals and shorten the maximum allowed communication distance.

DIP switches on the bottom of the OnCell G3151-HSPA are used to set the pull high/low resistor value for each
serial port.

OnCell G3111/G3151-HSPA Series Initial IP Address Configuration

Static and Dynamic IP Addresses

Determine whether your OnCell G3111/G3151-HSPA needs to use a static IP address or dynamic IP address
(either DHCP or BOOTP application).

• If your OnCell G3111/G3151-HSPA is used in a static IP environment, you must assign a specific IP
address using one of the tools described in this chapter.
• If your OnCell G3111/G3151-HSPA is used in a dynamic IP environment, the IP address will be
assigned automatically from over the network. In this case, set the IP configuration mode to DHCP or
BOOTP.

ATTENTION
Consult your network administrator on how to reserve a fixed IP address for your OnCell G3111/G3151-HSPA
in the MAC-IP mapping table when using a DHCP Server or BOOTP Server. For most applications, you should
assign a fixed IP address to your OnCell G3111/G3151-HSPA.

Factory Default IP Address

The OnCell G3111/G3151-HSPA is configured with the following default private IP address:

192.168.127.254

Note that IP addresses that begin with “192.168” are referred to as private IP addresses. Devices configured
with a private IP address are not directly accessible from a public network. For example, you would not be able
to ping a device with a private IP address from an outside Internet connection.

Configuration Options

OnCell Search Utility

You may configure your OnCell G3111/G3151-HSPA with the bundled OnCell Search Utility for Windows. Refer
to Appendix B, Software Installation/Configuration, for details on how to install and use OnCell Search Utility.

OnCell G3111/G3151-HSPA Series Initial IP Address Configuration

ARP
You may use the ARP (Address Resolution Protocol) command to set up an IP address for your OnCell
G3111/G3151-HSPA. The ARP command tells your computer to associate the OnCell G3111/G3151-HSPA’s
MAC address with an IP address. Afterwards, use Telnet to access the OnCell G3111/G3151-HSPA and its IP
address will be reconfigured.

ATTENTION
In order to use the ARP setup method, both your computer and the OnCell G3111/G3151-HSPA must be
connected to the same LAN. You may use an Ethernet cable to connect the OnCell G3111/G3151-HSPA directly
to your computer’s Ethernet card. Before executing the ARP command, your OnCell G3111/G3151-HSPA must
be configured with the factory default IP address (192.168.127.254) and your computer and the OnCell
G3111/G3151-HSPA must be on the same subnet.

To use ARP to configure the IP address, complete the following:

1. Obtain a valid IP address for your OnCell G3111/G3151-HSPA from your network administrator.
2. Obtain your OnCell G3111/G3151-HSPA’s MAC address from the label on the bottom panel.
3. Execute the arp -s command from your computer’s MS-DOS prompt as follows:
arp -s <IP address> <MAC address>

For example,

C:\> arp -s 192.168.200.100 00-90-E8-04-00-11

4. Next, execute a special Telnet command by entering the following exactly:

telnet 192.168.200.100 6000

When you enter this command, a Connect failed message will appear, as shown below.

5. After the OnCell G3111/G3151-HSPA reboots, its IP address will be assigned to the new address and you
can reconnect using Telnet to verify that the update was successful.

Basic Settings
The Basic Settings screen can be accessed from the navigation panel.

Server Settings

Server name: This is an optional free text field for your own use; it does not affect the operation of the OnCell
G3111/G3151-HSPA, and can be used to help differentiate one OnCell G3111/G3151-HSPA server from
another.

Server location: This is an optional free text field for your own use; it does not affect the operation of the
OnCell G3111/G3151-HSPA, and is useful for assigning or describing the location of an OnCell
G3111/G3151-HSPA. In a network environment of multiple servers, this can be a valuable aid when doing
maintenance.

Time Settings
The OnCell G3111/G3151-HSPA has a built-in Real-Time Clock for time calibration functions. Functions such as
Auto Warning Email or SNMP Trap can add real-time information to messages.

Before making any adjustments to the time, first select the correct time zone and submit the change. The
console will display the real time according to the time zone. To modify the real time clock, click on Modify next
to the Local time field. Once you submit the new time, the OnCell G3111/G3151-HSPA’s firmware will modify
the GMT time according to your time zone and local time settings.

ATTENTION
There is a risk of explosion if the real-time clock battery is replaced with the wrong type!
The OnCell G3111/G3151-HSPA’s real time clock is powered by a lithium battery. We strongly recommend that
you do not attempt to replace the lithium battery without help from a qualified Moxa support engineer. If you
need to change the battery, contact the Moxa RMA service team.

Time zone (default=GMT Greenwich Mean Time): This field shows the currently selected time zone and allows
you to select a different time zone.

Local time: This field shows the time that you last opened or refreshed the browser. To set the local time for
the OnCell G3111/G3151-HSPA, click on the Modify button, update the date and time, and then click on
submit.

OnCell G3111/G3151-HSPA Series Basic Settings and Network Settings

Time server: The OnCell G3111/G3151-HSPA uses SNTP (RFC-1769) for auto time calibration. You may enter
a time server IP address or domain name in this optional field. Once the OnCell G3111/G3151-HSPA is
configured with the correct time server address, it will request time information from the time server every 10
minutes.

Network Settings

Basic Network Settings

You can access Basic Network Settings by expanding the Network Settings item in the navigation panel.

Basic Network Settings is where you assign the OnCell G3111/G3151-HSPA’s IP address, netmask, gateway,
and other parameters for the Ethernet interface.

Note: You must assign a valid IP address to your OnCell G3111/G3151-HSPA before it will work in your
network environment. Your network system administrator should provide you with a unique IP address and
related settings for your network. First-time users can refer to Chapter 3, Initial IP Address Configuration,
for more information.

IP configuration (default=Static): You can choose from four possible IP configuration modes.

Option Description
Static User-defined IP address, netmask, and gateway.
DHCP DHCP server-assigned IP address, netmask, gateway, and DNS
DHCP/BOOTP DHCP server-assigned IP address, netmask, gateway, and DNS, or BOOTP
server-assigned IP address (if the DHCP server does not respond)
BOOTP BOOTP server-assigned IP address

IP Address (default=192.168.127.254): Enter the IP address that will be assigned to your OnCell
G3111/G3151-HSPA. All ports on the OnCell G3111/G3151-HSPA will share this IP address. An IP address is a
number assigned to a network device (such as a computer) as a permanent address on the network.
Computers use the IP address to identify and talk to each other over the network. Choose a proper IP address
that is unique and valid for your network environment.

Netmask (default=255.255.255.0): Enter the subnet mask. A subnet mask represents all of the network hosts
at one geographic location, in one building, or on the same local area network. When a packet is sent out over

5-3
OnCell G3111/G3151-HSPA Series Basic Settings and Network Settings

the network, the OnCell G3111/G3151-HSPA will use the subnet mask to check whether the desired TCP/IP
host specified in the packet is on the local network segment. If the address is on the same network segment as
the OnCell G3111/G3151-HSPA, a connection is established directly from the OnCell G3111/G3151-HSPA.
Otherwise, the connection is established through the given default gateway.

Gateway: Enter the IP address of the gateway if applicable. A gateway is a network computer that acts as an
entrance to another network. Usually, the computers that control traffic within the network or at the local
Internet service provider are gateway nodes. The OnCell G3111/G3151-HSPA needs to know the IP address of
the default gateway computer in order to communicate with the hosts outside the local network environment.
For correct gateway IP address information, consult the network administrator.

ATTENTION
In dynamic IP environments, the firmware will try to get the network settings from the DHCP or BOOTP server
3 times every 30 seconds until network settings are assigned by the DHCP or BOOTP server. The first try times
out after 1 second, the second after 3 seconds, and the third after 5 seconds.

If the DHCP/BOOTP server is unavailable, the firmware will use the default IP address (192.168.127.254),
netmask, and gateway settings.

WINS function (default=enable): Enable or disable the WINS (Windows Internet Naming Service) server.

WINS server: If a WINS Server is connected to the network, enter the WINS Server’s IP address in this field.
TCP/IP uses IP addresses to identify hosts, but users often use symbolic names, such as computer names. The
WINS Server, which uses NetBIOS over TCP/IP, contains a dynamic database to map computer names to IP
addresses.

LAN speed (default=Auto): You may configure the network speed for the built-in Ethernet connection on the
OnCell G3111/G3151-HSPA. IEEE802.3 Ethernet supports auto negotiation of transfer speed. However, some
switches/hubs require that the communication speed be fixed at 100 Mbps or 10 Mbps.

DHCP (default=Enable): DHCP stands for Dynamic Host Control Protocol. When you enable the DHCP Server,
it will automatically assign an IP address to the computers on the LAN or private network. Be sure to set
your computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.”
When you turn your computers on, they will automatically load the proper TCP/IP settings provided by the
OnCell 5000. The DHCP Server will automatically allocate an unused IP address from the IP address pool to
the requesting computer. You must specify the starting and ending address of the IP address pool.

DNS relay (default=Enable): If you enable DNS relay, your computers will use the router as a DNS server.
If you disable DNS relay, transfer the DNS server information from your ISP to your computers.

Start IP address: Enter the starting IP addresses for the DHCP server's IP assignment.

Maximum dynamic users: Enter the number of dynamic users. The maximum users you can enter may not
exceed 253, if your dynamic IP address begins with 192.168.127.1

Note: If you statically (manually) assign IP addresses to your computers or devices, make
sure the IP addresses are outside of this range to avoid IP address conflicts.

Client lease time: The length of time for the IP address lease. Enter the Lease time in minutes.

Static IP mapping: If enabled, the mapping list allows you to assign the DHCP IP within the range to your
specific device from MAC address.

5-4
OnCell G3111/G3151-HSPA Series Basic Settings and Network Settings

DNS Settings
You can access DNS Settings by expanding the Network Settings item in the navigation panel.

DNS server 1: This is an optional field. If your network has access to a DNS server, you may enter the DNS
server’s IP address in this field. This allows the OnCell G3111/G3151-HSPA to use domain names instead of IP
addresses to access hosts.

The Domain Name System (DNS) is used to identify Internet domain names, and translate the names into IP
addresses. A domain name is an alphanumeric name, such as www.moxa.com, that it is usually easier to
remember than the numeric IP address. A DNS server is a host that translates this kind of text-based domain
name into the actual IP address used to establish a TCP/IP connection.

When the user wants to visit a particular website, the user’s computer sends the domain name (e.g.,
www.moxa.com) to a DNS server to request that website’s numeric IP address. When the IP address is
received from the DNS server, the user’s computer uses that information to connect to the website’s web
server. The OnCell G3111/G3151-HSPA plays the role of a DNS client, in the sense that it actively queries the
DNS server for the IP address associated with a particular domain name. The following functions in the OnCell
G3111/G3151-HSPA’s web console support the use of domain names in place of IP addresses: Time Server,
Destination IP Address (in TCP Client mode), Mail Server, SNMP Trap Server, and SMTP Server.

DNS server 2: This is an optional field. The IP address of another DNS server may be entered in this field for
times when DNS server 1 is unavailable.

Advanced Network Settings

Access Advanced Network Settings by expanding the Network Settings item in the navigation panel.
Advanced Network Settings is where the gratuitous ARP is configured.

Gratuitous ARP: In some applications, you may need the OnCell G3111/G3151-HSPA to send broadcast
packets to update the ARP table on the server. If you enable this function and set the send period, the OnCell
G3111/G3151-HSPA will periodically send broadcast packets at the specified time interval.

Auto IP Report Settings

You can access Auto IP Report by expanding the Network Settings item in the navigation panel.

When the OnCell G3111/G3151-HSPA products are used in a dynamic IP environment, users must spend more
time with IP management tasks. For example, if the OnCell works as a server (TCP or UDP), then the host,
which acts as a client, must know the IP address of the server. If the DHCP server assigns a new IP address to
OnCell, the host must have some way of determining OnCell’s new IP address.

5-5
OnCell G3111/G3151-HSPA Series Basic Settings and Network Settings

OnCell G3111/G3151-HSPA products help out by periodically reporting their IP address to the IP location server,
in case the dynamic IP has changed. The parameters shown below are used to configure the Auto IP report
function. There are two ways to develop an “Auto IP report Server” to receive the OnCell’s Auto IP report.

1. Use the OnCell Search Utility’s IP Address Report function. Refer to OnCell Search Utility Configuration in
Appendix B – Software Installation/Configuration.
2. “Auto IP report protocol,” which can automatically receive the Auto IP report on a regular basis, is also
available to help you develop your own software. Refer to Appendix E for the “Auto IP report protocol.”

Auto IP report to host: Reports generated by the Auto report function will be sent automatically to this IP
address or host name.

Report to UDP port (default=63100): This is the UDP port number assignment for the serial port on the
OnCell G3111/G3151-HSPA.

Report period (default=99): You can use this option to set how often the IP address is automatically
reported.

ATTENTION
To use the OnCell Search Utility to receive the auto IP report message sent from the OnCell
G3111/G3151-HSPA,you must install the OnCell Windows Driver Manager. OnCell Windows Driver Manger
helps dispatch messages to the OnCell Search Utility.

Cellular Settings
This part of setting enables the WAN connection through cellular technologies. Refer to Chapter 6, Cellular

connection with an ISP after it reboots.

Cellular connection alive check (default=Disable): Some ISPs may disable the connection if there is no
data transmitted in a specific period of time, depending on the ISP’s settings. This function ensures that the
cellular connection will be kept alive even if no data is transmitted for a period of time by performing the check
action of DNS lookup or ping action of DNS/Ping remote host 1 or DNS/Ping remote host 2. If the check action
fails after the retry count number specified in “Cellular connection alive check retry count”, the OnCell will
re-establish a connection with the ISP.

Cellular connection alive check interval (min) (default=5 min): This setting specifies the idle time
before GuaranLink performs the check action.

Cellular connection alive check retry count (default=3 sec): This setting specifies the number of
attempts to reach the remote target(s) before the OnCell re-establishes a connection.

Port Setting Basics

To configure the operation mode and settings for a port, expand Serial Port Settings in the navigation panel,
and then expand the port that you would like to configure. Individual port settings are grouped into three
categories in the navigation panel: Operation Modes, Communication Parameters, and Data Buffering/Log.

Select Operation Modes in the navigation panel to select and configure the mode for each serial port.

Application: Select an application for the serial port from among the choices. Your application will determine
the modes that are available.

Mode: Once you have chosen an application, select the mode. The available configuration settings will vary
depending on the mode that you have selected.

Device Control Applications

Real COM Mode

TCP alive check time (default=7 min): This field specifies how long the OnCell G3111/G3151-HSPA will wait
for a response to “keep alive” packets before closing the TCP connection. The OnCell G3111/G3151-HSPA
checks connection status by sending periodic “keep alive” packets. If the remote host does not respond to the
packet within the time specified in this field, the OnCell G3111/G3151-HSPA will force the existing TCP
connection to close. For socket and device control modes, the OnCell G3111/G3151-HSPA will listen for another
TCP connection from another host after closing the connection. If TCP alive check time is set to 0, the TCP
connection will remain open and will not send any “keep alive” packets.

7-2
OnCell G3111/G3151-HSPA Series Configuring Serial Port Operation Modes

Max connection (default=1): This field is used if you need to receive data from different hosts
simultaneously. When set to 1, only one specific host can access this port of the OnCell G3111/G3151-HSPA,
and the OnCell COM driver on that host will have full control over the port. When set to 2, the specified number
of hosts’ OnCell COM driver may open this port at the same time. When multiple hosts’ OnCell COM driver open
the port at the same time, the COM driver only provides a pure data tunnel --no control ability unless “Allow
Driver Control” is enabled. The serial port parameters will use firmware settings instead of depending on your
application program (AP).

Application software that is based on the COM driver will receive a driver response of “success” when the
software uses any of the Win32 API functions. The firmware will only send data back to the driver on the host.

Data will be sent first-in-first-out when data comes into the OnCell G3111/G3151-HSPA from the Cellular or
Ethernet interface.

ATTENTION
When Max connection is greater than 1, the OnCell G3111/G3151-HSPA will use a multi connection
application (i.e., 2 hosts are allowed access to the port at the same time). When using a multi connection
application, the OnCell G3111/G3151-HSPA will use the serial communication parameters as defined here in
the web console, and all hosts connected to the port must use identical serial settings. If one of the hosts opens
the COM port with different serial settings, data will not be transmitted properly.

Ignore jammed IP (default=Disable): This option determines how the port will proceed if multiple hosts are
connected and one or more of the hosts stops responding as the port is transmitting data. If you select Disable,
the port will wait until the data has been transmitted successfully to all hosts before transmitting the next group
of data. If you select Enable, the port will ignore the host that stopped responding and continue data
transmission to the other hosts.

Allow driver control (default=Disable): This option determines how the port will proceed if driver control
commands are received from multiple hosts that are connected to the port. If Disable is selected, driver
control commands will be ignored. If Enable is selected, control commands will be accepted, with the most
recent command received taking precedence.

Connection goes down (default=always high): You can configure what happens to the RTS and DTR signals
when the Cellular or Ethernet connection goes down. For some applications, serial devices need to know the
Cellular or Ethernet link status through RTS or DTR signals sent through the serial port. Use “always low” if you
want the RTS and DTR signal to change their state to low when the Cellular or Ethernet connection gets
disconnected. Use “always high” if you do not want the cellular or Ethernet connection status to affect the RTS
or DTR signals.

Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed
to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximum
amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer
is full. When a packet length between 1 and 1024 bytes is specified, data in the buffer will be sent as soon it
reaches the specified length.

Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will queue the data
in the buffer and send the data to the Cellular or Ethernet port when a specific character, entered in hex format,
is received. A second delimiter character may be enabled and specified in the Delimiter 2 field, so that both
characters act as the delimiter to control when data should be sent.

ATTENTION
In order to enable a delimiter, packet length must be set to 0. Delimiter 2 should only be enabled in conjunction
with Delimiter 1 and never on its own; otherwise there may be data errors. Even when a delimiter is enabled,
the OnCell G3111/G3151-HSPA will still pack and send the data when the amount of data exceeds 1 KB.

7-3
OnCell G3111/G3151-HSPA Series Configuring Serial Port Operation Modes

Delimiter process (default=Do Nothing): The Delimiter process field determines how the data is handled
when a delimiter is received. Delimiter 1 must be enabled for this field to have effect. If Delimiters 1 and 2 are
both enabled, both characters must be received for the delimiter process to take place.

• Do Nothing: Data in the buffer will be transmitted when the delimiter is received.
• Delimiter + 1: Data in the buffer will be transmitted after 1 additional byte is received following the
delimiter.
• Delimiter + 2: Data in the buffer will be transmitted after 2 additional bytes are received following the
delimiter.
• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.

Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the OnCell
G3111/G3151-HSPA will allow before packing the serial data in its internal buffer for network transmission.

As data is received through the serial port, it is stored by the OnCell G3111/G3151-HSPA in the internal buffer.
The OnCell G3111/G3151-HSPA transmits data stored in the buffer via TCP/IP, but only when the internal
buffer is full or as specified by the force transmit time. When set to 0, the force transmit time is disabled, and
transmission is determined solely by the data in the internal buffer. At 1 to 65535, the TCP/IP protocol software
will pack the serial data received after there is a gap in serial communication that exceeds the specified force
transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character
interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits,
1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the
time required to transfer one character is

(10 (bits) / 1200 (bits/s)) × 1000 (ms/s) = 8.3 ms.

Therefore, you should set the force transmit time to be greater than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series
of characters within the specified force transmit time, and the total length of data must be less than or equal
to the OnCell G3111/G3151-HSPA’s internal buffer size (1 KB per port).

Disable, the port will wait until the data has been transmitted successfully to all hosts before transmitting the
next group of data. If you select Enable, the port will ignore the host that stopped responding and continue

Allow driver control (default=Disable): This option determines how the port will proceed if driver control
commands are received from multiple hosts that are connected to the port. If Disable is selected, driver
control commands will be ignored. If Enable is selected, control commands will be accepted, with the most
recent command received taking precedence.

Destination address 1 through 2 (default=None): Specifying an IP address allows the OnCell

G3111/G3151-HSPA to connect actively to the remote host. At least one destination must be provided.

TCP port (default=63950): This is the TCP port number assignment for the remote host/server. It is the port
number that the OnCell G3111/G3151-HSPA’s serial port uses to establish connections with a remote
host/server. To avoid conflicts with well-known TCP ports, the default is set to 63950.

Command port (default=63966): The Command port is the COM port for listening to SSDK commands from
the host. In order to prevent a COM port conflict with other applications, the user can set the Command port to
another port if needed.

ATTENTION
Up to 2 connections can be established between OnCell G3111/G3151-HSPA hosts.

Port 63950 might be blocked by a firewall. You should make sure the port is NOT blocked before you start using
it.

ATTENTION
The destination IP address parameter can be the IP address, domain name, or the name defined in the host
table.

Designated local port 1 through 2 (default=7010 through 7320): Use these fields to specify the designated local
ports.

Connection goes down (default=always high): You can configure what happens to the RTS and DTR
signals when the Cellular or Ethernet connection goes down. For some applications, serial devices need to know
the Cellular or Ethernet link status through RTS or DTR signals sent through the serial port. Use “always low”
if you want the RTS and DTR signal to change their state to low when the Cellular or Ethernet connection gets
disconnected. Use “always high” if you do not want the cellular or Ethernet connection status to affect the RTS
or DTR signals.

Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed
to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximum
amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer
is full. When a packet length between 1 and 1024 bytes is specified, data in the buffer will be sent as soon it

As data is received through the serial port, it is stored by the OnCell G3111/G3151-HSPA in the internal buffer.
The OnCell G3111/G3151-HSPA transmits data stored in the buffer via TCP/IP, but only when the internal

Therefore, you should set the force transmit time to be greater than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series

TCP alive check time (default=7 min): This field specifies how long the OnCell G3111/G3151-HSPA will wait
for a response to “keep alive” packets before closing the TCP connection. The OnCell G3111/G3151-HSPA
checks connection status by sending periodic “keep alive” packets. If the remote host does not respond to the

ATTENTION
You should make sure the inactivity time value used here is less than the inactivity time value on the
GSM/GPRS configuration page. The GSM/GPRS connection must be maintained in order to achieve the
inactivity time behavior of the TCP connection.

Inactivity time (default=0 ms): This field specifies how long the OnCell G3111/G3151-HSPA will wait for
incoming and outgoing data through the serial port before closing the TCP connection. The TCP connection is
closed if there is no incoming or outgoing data through the serial port for the specified Inactivity time. If this
field is set to 0, the TCP connection is kept active until a connection close request is received.

ATTENTION
If used, the Inactivity time setting should be greater than the Force transmit time. To prevent the
unintended loss of data due to the session being disconnected, it is highly recommended that this value is set
large enough so that the intended data transfer is completed.

Max connection (default=1): This field is used if you need to receive data from different hosts
simultaneously. When set to 1, only a single host may open the TCP connection to the serial port. When set to
2, the specified number of hosts may open this port at the same time. When multiple hosts establish a TCP
connection to the serial port at the same time, the OnCell G3111/G3151-HSPA will duplicate the serial data and
transmit it to all the hosts. Cellular or Ethernet data is sent on a first-in first-out basis to the serial port when
data comes into the OnCell G3111/G3151-HSPA from the Cellular or Ethernet interface.

delimiter.
• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.
Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the OnCell
G3111/G3151-HSPA will allow before packing the serial data in its internal buffer for network transmission.

As data is received through the serial port, it is stored by the OnCell G3111/G3151-HSPA in the internal buffer.
The OnCell G3111/G3151-HSPA transmits data stored in the buffer via TCP/IP, but only when the internal
buffer is full or as specified by the force transmit time. When set to 0, the force transmit time is disabled, and
transmission is determined solely by the data in the internal buffer. At 1 to 65535, the TCP/IP protocol software
will pack the serial data received after there is a gap in serial communication that exceeds the specified force
transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character
interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits,
1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the
time required to transfer one character is

(10 (bits) / 1200 (bits/s)) × 1000 (ms/s) = 8.3 ms.

Therefore, you should set the force transmit time to be larger than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series
of characters within the specified force transmit time, and the total length of data must be less than or equal
to the OnCell G3111/G3151-HSPA’s internal buffer size (1 KB per port).

TCP Client Mode

TCP alive check time (default=7 min): This field specifies how long the OnCell G3111/G3151-HSPA will wait
for a response to “keep alive” packets before closing the TCP connection. The OnCell G3111/G3151-HSPA
checks connection status by sending periodic “keep alive” packets. If the remote host does not respond to the
packet within the time specified in this field, the OnCell G3111/G3151-HSPA will force the existing TCP
connection to close. For socket and device control modes, the OnCell G3111/G3151-HSPA will listen for another
TCP connection from another host after closing the connection. If TCP alive check time is set to 0, the TCP
connection will remain open even if there is no response to the “keep alive” packets.

ATTENTION
You should make sure the inactivity time value used here is less than the inactivity time value on the
GSM/GPRS configuration page. The GSM/GPRS connection must be maintained in order to achieve the
inactivity time behavior of the TCP connection.

Inactivity time (default=0 ms): This field specifies how long the OnCell G3111/G3151-HSPA will wait for
incoming and outgoing data through the serial port before closing the TCP connection. The TCP connection is
closed if there is no incoming or outgoing data through the serial port for the specified Inactivity time. If this
field is set to 0, the TCP connection is kept active until a connection close request is received.

ATTENTION
If used, the Inactivity time setting should be greater than the Force transmit time. To prevent the
unintended loss of data due to the session being disconnected, it is highly recommended that this value is set
large enough so that the intended data transfer is completed.

ATTENTION
Inactivity time is ONLY active when Connection Control (see below) is set to Any character/Inactivity
time.

OnCell G3111/G3151-HSPA Series Configuring Serial Port Operation Modes

Ignore jammed IP (default=Disable): This option determines how the port will proceed if multiple hosts are
connected and one or more of the hosts stops responding as the port is transmitting data. If you select Disable,
the port will wait until the data has been transmitted successfully to all hosts before transmitting the next group
of data. If you select Enable, the port will ignore the host that stopped responding and continue data
transmission to the other hosts.

Destination address 1 through 4 (default=None): Specifying an IP address allows the OnCell

G3111/G3151-HSPA to connect actively to the remote host. At least one destination must be provided.

TCP port (default=4001): This is the TCP port number assignment for the serial port on the OnCell
G3111/G3151-HSPA. It is the port number that the serial port uses to make a connection, and that serial port
must use to contact the other devices. To avoid conflicts with well-known TCP ports, the default is set to 4001.

ATTENTION
Up to 4 connections can be established between the OnCell G3111/G3151-HSPA and hosts. The connection
speed or throughput may be low if any one of the four connections is slow, since the one slow connection will
slow down the other 3 connections.

ATTENTION
The Destination IP address parameter can be the IP address, domain name, or the name defined in the host
table. For some applications, the user may need to send the data actively to the remote destination domain
name.

Designated local port 1 through 4 (default=5010 through 5013): Use these fields to specify the designated
local ports.

Connection control (default=Startup/None): This setting determines the parameters under which a TCP
connection is established or disconnected. The different options are given in the following table. In general,
both the Connect condition and Disconnect conditions are given.

Option Description
Startup/None (default) A TCP connection will be established on startup, and will remain active indefinitely.
Any Character/None A TCP connection will be established when any character is received from the serial
interface, and will remain active indefinitely.
Any Character/ A TCP connection will be established when any character is received from the serial
Inactivity Time interface, and will be disconnected when Inactivity time is reached.
DSR On/DSR Off A TCP connection will be established when a DSR signal of OnCell is “On”, and will
remain active indefinitely.
DSR On/None A TCP connection will be established when a DSR “On” signal is received, and will
remain active indefinitely.
DCD On/DCD Off A TCP connection will be established when a DCD signal of OnCell is “On”, and will
remain active indefinitely.
DCD On/None A TCP connection will be established when a DCD “On” signal is received, and will
remain active indefinitely.

Packet length (default=0): This field refers to the maximum amount of data that is allowed to accumulate in
the serial port buffer before sending. At the default of 0 for packet length, no maximum amount is specified and
data in the buffer will be sent as specified by the delimiter settings or when the buffer is full. When a packet
length between 1 and 1024 bytes is specified, data in the buffer will be sent as soon it reaches the specified
length.

Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will clear the buffer
and send the data to the Ethernet port when a specific character, entered in hex format, is received. A second
delimiter character may be enabled and specified in the Delimiter 2 field, so that both characters act as the
delimiter to indicate when data should be sent.

7-13
OnCell G3111/G3151-HSPA Series Configuring Serial Port Operation Modes

ATTENTION
In order to enable a delimiter, packet length must be set to 0. Delimiter 2 should only be enabled in conjunction
with Delimiter 1 and never on its own; otherwise there may be data errors. Even when a delimiter is enabled,
the OnCell G3111/G3151-HSPA will still pack and send the data when the amount of data exceeds 1 KB.

Delimiter process (default=Do Nothing): The Delimiter process field determines how the data is handled
when a delimiter is received. Delimiter 1 must be enabled for this field to have effect. If Delimiters 1 and 2 are
both enabled, both characters must be received for the delimiter process to take place.

• Do Nothing: Data in the buffer will be transmitted when the delimiter is received.
• Delimiter + 1: Data in the buffer will be transmitted after 1 additional byte is received following the
delimiter.
• Delimiter + 2: Data in the buffer will be transmitted after 2 additional bytes are received following the
delimiter.
• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.

Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the OnCell
G3111/G3151-HSPA will allow before packing the serial data in its internal buffer for network transmission.

As data is received through the serial port, it is stored by the OnCell G3111/G3151-HSPA in the internal buffer.
The OnCell G3111/G3151-HSPA transmits data stored in the buffer via TCP/IP, but only when the internal
buffer is full or as specified by the force transmit time. When set to 0, the force transmit time is disabled, and
transmission is determined solely by the data in the internal buffer. At 1 to 65535, the TCP/IP protocol software
will pack the serial data received after there is a gap in serial communication that exceeds the specified force
transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character
interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits,
1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the
time required to transfer one character is

(10 (bits) / 1200 (bits/s)) × 1000 (ms/s) = 8.3 ms.

Therefore, you should set the force transmit time to be larger than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series
of characters within the specified force transmit time, and the total length of data must be less than or equal
to the OnCell G3111/G3151-HSPA’s internal buffer size (1 KB per port).

UDP Mode

Destination address 1 through 4 (default=None): In UDP mode, you may specify up to 4 ranges of IP
addresses for the serial port to connect to. At least one destination range must be provided.

ATTENTION
The maximum selectable IP address range is 64 addresses. However, when using multicast, you may enter IP
addresses of the form xxx.xxx.xxx.255 in the Begin field. For example, enter 192.168.127.255 to allow the
OnCell G3111/G3151-HSPA to broadcast UDP packets to all hosts with IP addresses between 192.168.127.1
and 192.168.127.254.

Local listen port (default=4001): This is the UDP port that the OnCell G3111/G3151-HSPA listens to and that
other devices must use to contact the OnCell G3111/G3151-HSPA. To avoid conflicts with well-known UDP
ports, the default is set to 4001.

Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed
to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximum
amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer
is full. When a packet length between 1 and 1024 bytes is specified, data in the buffer will be sent as soon it
reaches the specified length.

Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will clear the buffer
and send the data to the Ethernet port when a specific character, entered in hex format, is received. A second
delimiter character may be enabled and specified in the Delimiter 2 field, so that both characters act as the

both enabled, both characters must be received for the delimiter process to take place.

• Do Nothing: Data in the buffer will be transmitted when the delimiter is received.
• Delimiter + 1: Data in the buffer will be transmitted after 1 additional byte is received following the
delimiter.

Therefore, you should set the force transmit time to be larger than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series
of characters within the specified force transmit time, and the total length of data must be less than or equal
to the OnCell G3111/G3151-HSPA’s internal buffer size (1 KB per port).

Ethernet Modem Mode

The OnCell G3111/G3151-HSPA accepts the AT command ATD IP address:TCP port (for example, ATD
192.168.127.1:4001) from the serial port and then requests a TCP connection from the remote Ethernet
Modem or PC. Here IP address is the IP address of the remote Ethernet modem or PC, and TCP port is the TCP
port number of the remote Ethernet modem or PC. Once the remote unit accepts this TCP connection, the
OnCell G3111/G3151-HSPA will send out the “CONNECT baud” signal via the serial port and then enter data
mode.

TCP alive check time (default=7 min): This field specifies how long the OnCell G3111/G3151-HSPA will wait
for a response to “keep alive” packets before closing the TCP connection. The OnCell G3111/G3151-HSPA
checks connection status by sending periodic “keep alive” packets. If the remote host does not respond to the
packet within the time specified in this field, the OnCell G3111/G3151-HSPA will force the existing TCP
connection to close. For socket and device control modes, the OnCell G3111/G3151-HSPA will listen for another
TCP connection from another host after closing the connection. If TCP alive check time is set to 0, the TCP
connection will remain open even if there is no response to the “keep alive” packets.

TCP port (default=4001): This is the TCP port number assignment for the serial port on the OnCell
G3111/G3151-HSPA. It is the port number that the serial port uses to listen to connections, and that other
devices must use to contact the serial port. To avoid conflicts with well-known TCP ports, the default is set to
4001.

OnCell G3111/G3151-HSPA Series Configuring Serial Port Operation Modes

Dial-in
The OnCell G3111/G3151-HSPA listens for a TCP/IP connection request from the remote Ethernet modem or
host. The OnCell G3111/G3151-HSPA’s response depends on the ATS0 value, as follows.

ATS0=0:

The OnCell G3111/G3151-HSPA will temporarily accept the TCP connection and then send the RING signal out
through the serial port. The serial controller must reply with ATA within 2.5 seconds to accept the connection
request, after which the OnCell G3111/G3151-HSPA enters data mode. If no ATA command is received, the
OnCell G3111/G3151-HSPA will disconnect after sending three RING signals.

ATS0≧1:

The OnCell G3111/G3151-HSPA will accept the TCP connection immediately and then send the “CONNECT
baud” command to the serial port, in which baud represents the baudrate of the OnCell G3111/G3151-HSPA’s
serial port. After that, the OnCell G3111/G3151-HSPA immediately enters data mode.

Dial-out
The OnCell G3111/G3151-HSPA accepts the AT command “ATD IP:TCP port” from the serial port and then
requests a TCP connection from the remote Ethernet Modem or PC. Here IP is the IP address of the remote
Ethernet modem or PC, and TCP port is the TCP port number of the remote Ethernet modem or PC. Once the
remote unit accepts this TCP connection, the OnCell G3111/G3151-HSPA will send out the CONNECT baud”
signal via the serial port and then enter data mode.

Disconnection request from local site

When the OnCell G3111/G3151-HSPA is in data mode, the user can initiate disconnection by sending “+++”
from the local serial port to the OnCell G3111/G3151-HSPA. Some applications allow you to set the DTR signal
to off, which will also initiate disconnection. The OnCell G3111/G3151-HSPA will enter command mode, and
after 1 second, you can then enter ATH to shut down the TCP connection. The OnCell G3111/G3151-HSPA will
return a NO CARRIER via the serial port.

Note: The “+++” command cannot be divided. The “+” character can be changed in register S2, and the guard
time, which prefixes and suffixes the “+++” in order to protect the raw data, can be changed in register S12.

Disconnection request from remote site

After the TCP connection has been shut down by the remote Ethernet modem or PC, the OnCell
G3111/G3151-HSPA will send the NO CARRIER signal via the serial port and then return to command mode.

AT Commands

ATTENTION
1. The Target Phone Number must be specified if SMS-OUT is activated.
2. The Target Phone Number and Caller ID can be written in either international format, starting with “+”
followed by the country code, or local format, starting with local area code.
3. If you don’t use Caller ID authentication, the OnCell G3111/G3151-HSPA will allow all incoming short
messages as serial data to be forwarded to its serial port. This includes system broadcasts and
advertisements.

Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed
to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximum
amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer
is full. When a packet length between 1 and 160 bytes is specified, data in the buffer will be sent as soon it
reaches the specified length.

Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will queue the data
in the buffer and send the data to the Cellular or Ethernet port when a specific character, entered in hex format,
is received. A second delimiter character may be enabled and specified in the Delimiter 2 field, so that both
characters act as the delimiter to control when data should be sent.

ATTENTION
In order to enable a delimiter, packet length must be set to 0. Delimiter 2 should only be enabled in conjunction
with Delimiter 1 and never on its own; otherwise there may be data errors. Even when a delimiter is enabled,
the OnCell G3111/G3151-HSPA will still pack and send the data when the amount of data exceeds 1 KB.

Delimiter process (default=Do Nothing): The Delimiter process field determines how the data is handled
when a delimiter is received. Delimiter 1 must be enabled for this field to have effect. If Delimiters 1 and 2 are
both enabled, both characters must be received for the delimiter process to take place.

• Do Nothing: Data in the buffer will be transmitted when the delimiter is received.
• Delimiter + 1: Data in the buffer will be transmitted after 1 additional byte is received following the
delimiter.
• Delimiter + 2: Data in the buffer will be transmitted after 2 additional bytes are received following the
delimiter.
• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.

Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the OnCell
G3111/G3151-HSPA will allow before packing the serial data in its internal buffer for network transmission.

As data is received through the serial port, it is stored by the OnCell G3111/G3151-HSPA in the internal buffer.
The OnCell G3111/G3151-HSPA transmits data stored in the buffer via SMS, but only when the internal buffer
is full or as specified by the force transmit time. When set to 0, the force transmit time is disabled, and
transmission is determined solely by the data in the internal buffer. At 1 to 65535, the SMS protocol software
will pack the serial data received after there is a gap in serial communication that exceeds the specified force
transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character
interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits,
1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the
time required to transfer one character is

(10 (bits) / 1200 (bits/s)) × 1000 (ms/s) = 8.3 ms.

Therefore, you should set the force transmit time to be larger than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series
of characters within the specified force transmit time, and the total length of data must be less than or equal
to the OnCell G3111/G3151-HSPA’s internal buffer size.

Communication Parameters

Port alias: This optional field allows you to assign an alias to a port for easier identification.

Serial Parameters

ATTENTION
The serial parameters for the each serial port on the OnCell G3111/G3151-HSPA should match the parameters
used by the connected serial device. You may need to refer to your serial device’s user’s manual to determine
the appropriate serial communication parameters.

Baudrate (default=115200 bps): This field configures the port’s baudrate. Select one of the standard
baudrates from the dropdown box, or select Other and then type the desired baudrate in the input box.

ATTENTION
If the port requires a special baudrate that is not listed, such as G3111/G3151-HSPA00 bps, you may can select
the Other option and enter the desired baudrate into the text box. The OnCell G3111/G3151-HSPA will
automatically calculate the closest supported baudrate. The margin for error will be less than 1.7% for all
baudrates under 921600 bps.

Data bits (default=8): This field configures the data bits parameter.

Note: If data bits are set to 5 bits, stop bits will automatically be set to 2 bits

Stop bits (default=1): This field configures the stop bits parameter.

Note: If data bits are set to 5 bits, stop bits will automatically be set to 1.5 bits

Parity (default=None): This field configures the parity parameter.

Flow control (default=RTS/CTS): This field configures the flow control type.

FIFO (default=Enable): This field enables or disables the 128-byte FIFO buffer. The OnCell
G3111/G3151-HSPA provides FIFO buffers for each serial port, for both the Tx and Rx signals. Note, however,
that you should disable the port’s FIFO setting if the attached serial device does not have a FIFO buffer of its
own. This is because a serial device that does not have its own buffer may not be able to keep up with data sent
from the OnCell’s FIFO buffer.

Interface (default=RS-232): You may configure the serial interface to RS-232, RS-422, RS-485 2-wire, or
RS-485 4-wire.

Data Buffering/Log

The OnCell G3111/G3151-HSPA supports port buffering to prevent the loss of serial data when the Cellular or
Ethernet connection is down. Port buffering can be used in Real COM, Reverse Real COM, RFC2217, TCP Server,

Misc. Network Settings

Accessible IP List

The OnCell G3111/G3151-HSPA uses an IP address-based filtering method to control access to its serial ports.

The Accessible IP list allows you restrict network access to the OnCell G3111/G3151-HSPA. Access is controlled
by IP address. When the accessible IP list is enabled, a host’s IP address must be listed in order to gain access
to the OnCell G3111/G3151-HSPA. You may add a specific address or range of addresses by using a
combination of IP address and netmask, as follows:

To allow access to a specific IP address

Enter the IP address in the corresponding field; enter 255.255.255.255 for the netmask.

To allow access to hosts on a specific subnet

For both the IP address and netmask, use 0 for the last digit (e.g., 192.168.1.0 and 255.255.255.0).

To allow unrestricted access

Deselect the Enable the accessible IP list option.

Refer to the following table for more configuration examples.

Allowed hosts Entered IP address/Netmask

Virtual Server Settings

Virtual Server Settings (default=Disable): This function allows remote users to access the Host or FTP
services via a public IP address, and automatically redirects them to local servers in the LAN (Local Area
Network).

The OnCell firewall feature filters out unrecognized packets to protect your LAN network when computers
networked with the OnCell are hidden from public view. If you wish, you can make some of the LAN computers
accessible from the Internet by enabling Virtual Server. Depending on the requested service, the OnCell
redirects the external service request to the appropriate server within the LAN network.

The OnCell is also capable of port-redirection meaning incoming traffic to a particular port may be redirected to
a different port on the server computer.

OnCell G3111/G3151-HSPA Series System Management Settings

Serial Event Settings

On the Serial Event Settings page, you may configure how administrators are notified of each serial port’s DCD
and DSR changes. Mail refers to sending an e-mail to a specified address. Trap refers to sending an SNMP Trap.
Dout refers to changing the status of the relay output. SMS refers to sending a message to one or more
specified phone numbers.

DCD changed

A change in the DCD (Data Carrier Detect) signal indicates that the modem connection status has changed. For
example, if the DCD signal changes to low, it indicates that the connection line is down. When the DCD signal
changes to low, the OnCell G3111/G3151-HSPA will automatically send a warning to the administrator as
configured on the Serial Event Settings page.

For relay output function, after the relay output status has been changed, administrators may reset its status
by selecting Acknowledge Event from the OnCell G3111/G3151-HSPA console, or by correcting the DCD
signal. Refer to the section on System Monitoring later in this chapter for more information.

DSR changed

A change in the DSR (Data Set Ready) signal indicates that the data communication equipment is powered off.
For example, if the DSR signal changes to low, it indicates that the data communication equipment is powered
down. When the DSR signal changes to low, the OnCell G3111/G3151-HSPA will automatically send a warning
to the administrator as configured on the Serial Event Settings page.

For relay output function, after the relay output status has been changed, administrators may reset its status
by selecting Acknowledge Event from the OnCell G3111/G3151-HSPA console, or by correcting the DSR
signal. Refer to the section on System Monitoring later in this chapter for more information.

ATTENTION
SNMP indicates a change in DCD or DSR signals but does not differentiate between the two. A change in either
signal from “–” to “+” is indicated by “link up” and a change in either signal from “+” to “–” is indicated by “link
down.”

Remote SMS Control

Remote SMS Control can be used when your OnCell devices are installed in locations that are not easy to
access and where GPRS service is unstable. SMS service is one of the most reliable cellular services. Remote
SMS control provides: 1) the ability to report the current status of the OnCell device to your SMS sender; 2) the
ability to reboot the device so it can be recovered from any unexpected situation.

Remote SMS Control: Enable or disable the ability of the OnCell to be controlled by SMS (default: disabled).
Password: Set your password (4-16 characters).
Auth type: You can restrict the access by enabling the Caller ID under Auth Type.
Caller ID: Enter Caller ID number so that only SMS from specific senders can trigger Remote SMS control.
restart: When receiving the SMS message [@password@restart], the device will reboot. For example, if
Password=12345, then sending an SMS notification that reads @12345@restart to the OnCell will reboot the
OnCell.
cell. report: When receiving the SMS message [@password@cell.report], the device will reply with the current
cellular status.
Action: Execute an operation upon receiving an SMS notification.

Acknowledge: Reply to the SMS sender with an SMS message after the operation is completed.

A. Introduction to Serial Port Operation
Modes

In this chapter, we describe the various operation modes of the OnCell G3111/G3151-HSPA. The OnCell
G3111/G3151-HSPA modes are grouped by type of application, such as Device Control. The options include an
operation mode that relies on a driver installed on the host computer, and operation modes that rely on TCP/IP
socket programming concepts. After selecting the proper operation mode, refer to Chapter 7, Serial
Operation Mode Settings, for detailed information on configuration parameters.

Overview

The OnCell G3111/G3151-HSPA cellular IP gateway enables traditional serial (RS-232/422/485) devices for
transmitting data over the cellular network. The IP gateway is a tiny computer equipped with a CPU and TCP/IP
protocols that can bi-directionally translate data between the serial and IP formats. With the OnCell
G3111/G3151-HSPA, your computer will be able to access, manage, and configure remote facilities and
equipment over the cellular network from anywhere in the world.

Traditional SCADA and data collection systems rely on serial ports to collect data from various kinds of
instruments. Since the OnCell G3111/G3151-HSPA cellular IP gateway network-enables instruments equipped
with an RS-232, RS-422, or RS-485 communication port, your SCADA and data collection system will be able
to access all instruments connected to a standard TCP/IP network, regardless of whether the devices are used
locally or at a remote site.

The OnCell G3111/G3151-HSPA is an external IP-based network device that allows you to expand a serial port
for a host computer on demand. As long as your host computer supports the TCP/IP protocol, you will not be
limited by the host computer’s bus limitation (such as ISA or PCI), nor will you be limited if you do not have
drivers for various operating systems.

In addition to providing socket access, the OnCell G3111/G3151-HSPA also comes with a Real COM/TTY driver
and a Reverse Real COM/TTY driver that transmits all serial signals intact. This enables you to preserve your
existing COM/TTY-based software without needing to invest in additional software.

Three different socket modes are available: TCP Server, TCP Client, and UDP. The main difference between the
TCP and UDP protocols is that TCP guarantees delivery of data by requiring the recipient to send an
acknowledgement to the sender. UDP does not require this type of verification, making it possible to offer faster
delivery. UDP also allows you to unicast data to one IP, or multicast the data to a group of IP addresses.
OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

Device Control Applications

The OnCell G3111/G3151-HSPA offers the following modes for device control applications: Real COM, Reverse
Real COM, and RFC2217 modes.

Real COM Modes

The OnCell G3111/G3151-HSPA comes bundled with Moxa drivers for Windows
NT/2000/XP/2003/2008/Vista/7 systems and TTY drivers for Linux and Unix systems. (For Windows systems,
this option is only supported for Windows 2000, XP x86/x64, 2003 x86/x64, Vista x86/x64, 2008 x86/x64 and
Windows 7 x86/x64.)

In Real COM mode, the bundled drivers are able to establish a transparent connection between a host and a
serial device by mapping the serial port on the OnCell G3111/G3151-HSPA to a local COM/TTY port on the host
computer. Real COM mode supports up to 2 simultaneous connections that enable 2 hosts to simultaneously
collect data from the same serial device.

One of the major conveniences of using Real COM mode is that it allows you to use software that was written
for pure serial communication applications. The OnCell COM driver intercepts data sent to the host’s COM port,
packs it into a TCP/IP packet, and then redirects it through the host’s Ethernet card to the Internet. At the other
end of the connection, the OnCell G3111/G3151-HSPA accepts the IP frame from the cellular network, unpacks
the TCP/IP packet, and then transparently sends the data through the serial port to the attached serial device.

Types of Real COM Connections

This section illustrates the types of Real COM connections you can use, depending on the service you obtain
from your local cellular service provider.

1. Fixed Public IP for OnCell.

If your cellular service provider offers a fixed public IP address after you connect to the cellular network,
you can access the OnCell G3111/G3151-HSPA via a host PC using either a private IP or public IP.

2. Utilize Auto IP report.

If your cellular service provider offers a dynamic public IP address after you connect to the cellular network,
you can access the OnCell G3111/G3151-HSPA via a host PC using a fixed public IP. Since the IP address

A-2
OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

of the OnCell G3111/G3151-HSPA is changed each time it is connected to the cellular network, the host IP
can be notified of the change by an Auto IP Report message sent from the OnCell G3111/G3151-HSPA.
Refer to Appendix E to see the format of the Auto IP Report Protocol.

3. Domain name with DDNS.

If your cellular service provider offers a public IP address after you connect to the cellular network, you can
also access the OnCell G3111/G3151-HSPA using the domain name. To do this, you will need to register
with a DDNS service provider and then enable the DDNS function in the OnCell G3111/G3151-HSPA. Refer
to Appendix C for more information.

Reverse Real COM Modes

The OnCell G3111/G3151-HSPA comes bundled with Moxa drivers for Windows
NT/2000/XP/2003/2008/Vista/7 systems and TTY drivers for Linux and Unix systems. (For Windows systems,
this option is only supported for Windows 2000, XP x86/x64, 2003 x86/x64, Vista x86/x64, 2008 x86/x64 and
Windows 7 x86/x64.)

Reverse Real COM mode uses a mechanism similar to port mapping to enable your remote device that is using
a private IP address to remain accessible to external hosts. When this mode is enabled, the Moxa driver that
comes with the device establishes a transparent connection from the device to the remote host by mapping the
device’s serial port to a local COM port on the remote host. Reverse Real COM mode supports up to 2
simultaneous connections that enable serial devices to send data to 2 hosts simultaneously.

Types of Reverse Real COM Connection

1. Reverse Real COM to PC’s IP address.
Most cellular service providers only provide customers with a dynamic private IP address, which means that
the OnCell G3111/G3151-HSPA will only obtain an IP address once it is connected to the cellular network.
Reverse Real COM is a great feature that allows a PC host to access an OnCell G3111/G3151-HSPA
configured with a private IP address.

2. Reverse Real COM to PC’s domain name.

With Reverse Real COM mode, you can connect to a PC host using the PC’s IP address. You can also connect
to your PC host with the PC’s domain name, if you have one. Refer to Appendix C for more information.

RFC 2217 Mode

RFC-2217 mode is similar to Real COM mode in that a driver is used to establish a transparent connection
between a host computer and a serial device by mapping the serial port on the OnCell G3111/G3151-HSPA to
a local COM port on the host computer. RFC2217 defines general COM port control options based on the Telnet
protocol. Third party drivers supporting RFC-2217 are widely available on the Internet and can be used to
implement virtual COM mapping to your OnCell G3111/G3151-HSPA’s serial port. Refer to Appendix B for more
information.

Socket Applications
The OnCell G3111/G3151-HSPA offers the following modes for socket applications: TCP Server, TCP Client, and
UDP.

TCP Server Modes

In TCP Server mode, the serial port on the OnCell G3111/G3151-HSPA is assigned a port number. The host
computer initiates contact with the OnCell G3111/G3151-HSPA, establishes the connection, and receives data
from the serial device. This operation mode also supports up to 2 simultaneous connections, enabling multiple
hosts to collect data from the same serial device at the same time.

As illustrated in the figure, data transmission proceeds as follows: The host requests a connection from the
OnCell G3111/G3151-HSPA, which is configured for TCP Server mode. Once the connection is established, data
can be transmitted in both directions between the host and the OnCell G3111/G3151-HSPA.

A-4
OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

Types of TCP Server Connection

1. Fixed Public IP for the OnCell.
If your cellular service provider offers a fixed public IP address after you connect to the cellular network,
you can access the OnCell G3111/G3151-HSPA from a host PC using either a private IP or public IP.

2. Using Auto IP report.

If your cellular service provider offers a dynamic public IP address after you connect to the cellular network,
you can access the OnCell G3111/G3151-HSPA from a host PC using a fixed public IP. Since the IP address
of the OnCell G3111/G3151-HSPA is changed every time it is connected to the cellular network, the host IP
can be aware of the change by the Auto IP Report message sent from the OnCell G3111/G3151-HSPA. Refer
to Appendix E for the format of the Auto IP Report Protocol.

3. Domain name with DDNS.

If your cellular service provider offers a public IP address after you connect to the cellular network, you can
also use the domain name to access the OnCell G3111/G3151-HSPA. You would need to register with a
DDNS service provider and then enable the DDNS function in the OnCell G3111/G3151-HSPA. Refer to
Appendix C for more information.

A-5
OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

4. Connecting TCP client and TCP server within the same cellular service provider.
In order to connect properly, the IP addresses of the two OnCell devices must belong to the same
subnetwork. To ensure that this is the case, use the same cellular service provider to connect the devices
to the network. In addition, you will need to request that the cellular service provider provide you with two
private IP addresses (e.g., 192.168.1.1 and 192.168.1.2).

TCP Client Modes

In TCP Client mode, the OnCell G3111/G3151-HSPA can actively establish a TCP connection to a pre-defined
host computer when serial data arrives. After the data has been transferred, the OnCell G3111/G3151-HSPA
can automatically disconnect from the host computer by using the Inactivity time settings.

As illustrated in the figure below, data transmission proceeds as follows:

(1) The OnCell G3111/G3151-HSPA, configured for TCP Client mode, requests a connection to the host.

(2) Once the connection is established, data can be transmitted in both directions between the host and the
OnCell G3111/G3151-HSPA.

Types of TCP Client Connection

1. TCP Client to PC’s IP address.
The OnCell G3111/G3151-HSPA will only be able to connect to a host PC if the PC is using a public IP
address.

A-6
OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

2. TCP Client to PC’s domain name.

To connect to a host PC, the host PC must be configured with public IP address. If it is using a dynamic
public IP, then the OnCell G3111/G3151-HSPA can connect to it using the host’s domain name. Refer to
Appendix C for more information.

3. Connecting TCP client and TCP server within the same cellular service provider.
In order to connect properly, the IP addresses of the two OnCell devices must belong to the same
subnetwork. To ensure that this is the case, use the same cellular service provider to connect the devices
to the network. In addition, you will need to request that the cellular service provider provide you with two
private IP addresses (e.g., 192.168.1.1 and 192.168.1.2).

UDP Mode
Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can unicast to one host
or multicast to multiple hosts and the serial device can receive data from one or multiple host computers. These
traits make UDP mode especially well-suited for message display applications.

A-7
OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

Types of UDP Connection

1. Fixed Public IPs for both OnCell and Host PC.
If your cellular service provider offers a fixed public IP address after you connect to the cellular network,
you can access the OnCell G3111/G3151-HSPA from a host PC that has a fixed public IP.

2. Domain name with DDNS.

If your cellular service provider assigns a public IP address after you connect to the cellular network, you
can also access the OnCell G3111/G3151-HSPA using the domain name. If your service provider assigns a
public IP address (either fixed or dynamic) to your cellular device and your control center is the side that
initiates the connection, you can enable the DDNS function and UDP mode to allow other devices on the
Internet to connect to your device using its domain name. This will ensure that your device will remain
reachable even when its public IP address is updated. Note that you will need to register your device with
a DDNS server. Refer to Appendix C for more information.

A-8
OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

Ethernet Modem Mode

Ethernet Modem mode is designed for use with legacy operating systems, such as MS-DOS, that do not support
TCP/IP networks. By connecting a properly configured OnCell G3111/G3151-HSPA serial port to the MS-DOS
computer’s serial port, it is possible to use legacy software to transmit data over the cellular network, even if
the software was originally designed to transmit data through a modem. In this case, the AT commands are
converted into IP format.

SMS Tunnel Mode

A major benefit of GSM technology is that it supports short messages (SMS) for easy communication over the
mobile network. Moxa’s proprietary SMS Tunnel Mode allows you to expand your applications and reduce cost.
For example, SMS Tunnel Mode can be used to update the message on a highway display panel, place refill
orders for vending machines, handle maintenance for remote rental equipment, or even help create an SMS
alarm by directly transforming text, binary, or unicode data from a legacy device to short messages. SMS
Tunnel Mode is particularly suitable for devices that communicate infrequently, or lack access to the local
network. SMS Tunnel Mode converts ASCII, binary code, and UCS2 data to short messages transparently (both
back and forth). In addition, the caller ID (phone number) identification can be used to block messages sent
from uncertified users, broadcast messages, and unwanted SMS advertisements.

Moxa’s proprietary SMS Tunnel Mode has the following features:

1. Transparently converts serial data to short message, and vice versa.

2. Text, binary, and Unicode formats are supported.
3. Verification of Incoming Caller ID calls is implemented to block uncertified users.

Disabled Mode
You can disable the serial port on the OnCell G3111/G3151-HSPA by setting the operation mode to Disabled.

OnCell Windows Driver Manager

Installing OnCell Windows Driver Manager

OnCell Windows Driver Manager is intended for use with OnCell G3111/G3151-HSPA serial ports that are set to
Real COM mode. The software manages the installation of drivers that allow you to map unused COM ports on
your PC to serial ports on the OnCell G3111/G3151-HSPA. These drivers are designed for use with Windows
NT/2000/XP/2003/2008/Vista/7. When the drivers are installed and configured, devices that are attached to
serial ports on the OnCell G3111/G3151-HSPA will be treated as if they were attached to your PC’s own COM
ports.

Using OnCell Windows Driver Manager

After you install OnCell Windows Driver Manager, you can set up the OnCell G3111/G3151-HSPA’s serial ports
as remote COM ports for your PC host. Make sure that the serial port(s) on your OnCell G3111/G3151-HSPA are
set to Real COM mode when mapping COM ports with OnCell Windows Driver Manager.

1. Go to Start  OnCell Windows Driver Manager  OnCell Windows Driver Manager to start the COM
mapping utility.
2. Click the Add icon.

3. Click Rescan to search for OnCell IP gateway. From the list that is generated, select the server that you will
map COM ports to, and then click OK.

Alternatively, for Real COM mode, you can select Input Manually and then manually enter the OnCell
G3111/G3151-HSPA’s IP Type. To do this, select LAN type, followed by 1st Data Port, and 1st Command

B-8
OnCell G3111/G3151-HSPA Series Software Installation/Configuration

7. On the Basic Setting page, use the COM Number drop-down list to select a COM number to be assigned
to the OnCell G3111/G3151-HSPA’s serial port that is being configured. Note that ports that are “in use” will
be labeled accordingly.

8. Click the Advanced Setting tab to modify Tx Mode, FIFO, Fast Flush, and other parameters.

Tx Mode
Hi-Performance is the default for Tx mode. After the driver sends data to the OnCell G3111/G3151-HSPA,
the driver immediately issues a “Tx Empty” response to the program. Under Classical mode, the driver will
not send the “Tx Empty” response until after confirmation is received from the OnCell
G3111/G3151-HSPA’s serial port. This causes lower throughput. Classical mode is recommended if you
want to ensure that all data is sent out before further processing.

B-9
OnCell G3111/G3151-HSPA Series Software Installation/Configuration

FIFO
If FIFO is Disabled, the OnCell G3111/G3151-HSPA will transmit one byte each time the Tx FIFO becomes
empty, and an Rx interrupt will be generated for each incoming byte. This will result in a faster response
and lower throughput.

Network Timeout
You can use this option to prevent blocking if the target OnCell is unavailable.

Auto Network Re-Connection

With this option enabled, the driver will repeatedly attempt to re-establish the TCP connection if the OnCell
G3111/G3151-HSPA does not respond to background “check alive” packets.

Return error if network is unavailable

If this option is disabled, the driver will not return any error even when a connection cannot be established
to the OnCell G3111/G3151-HSPA. With this option enabled, calling the Win32 Comm function will result in
the error return code “STATUS_NETWORK_UNREACHABLE” when a connection cannot be established to the
OnCell G3111/G3151-HSPA. This usually means that your host’s network connection is down, perhaps due
to a cable being disconnected. However, if you can reach other network devices, it may be that the OnCell
G3111/G3151-HSPA is not powered on or is disconnected. Note that Auto Network Re-Connection must
be enabled in order to use this function.

Fast Flush (only flushes the local buffer)

For some applications, the user’s program will use the Win32 “PurgeComm()” function before it reads or
writes data. After a program uses this PurgeComm() function, the OnCell driver continues to query the
OnCell’s firmware several times to make sure no data is queued in the OnCell firmware buffer, rather than
just flushing the local buffer. This design is used to satisfy some special considerations. However, it may
take more time (about several hundred milliseconds) than a native COM1 due to the additional time spent
communicating across the Ethernet. This is why PurgeComm() works significantly faster with native COM
ports on the PC than with mapped COM ports on the OnCell G3111/G3151-HSPA. In order to accommodate
other applications that require a faster response time, the new OnCell driver implements a new Fast Flush
option. By default, this function is enabled.

If you have disabled Fast Flush and find that COM ports mapped to the OnCell G3111/G3151-HSPA perform
markedly slower than when using a native COM port, try to verify if “PurgeComm()” functions are used in
your application. If so, try enabling the Fast Flush function and see if there is a significant improvement in
performance.

Auto IP Report: When OnCell G3111/G3151-HSPA products are used in a dynamic IP environment, users
must spend more time with IP management tasks. For example, if the OnCell works as a server (Real COM
mode, TCP Server mode, or UDP mode), then the host, which acts as a client, must know the IP address of
the server. If the DHCP server assigns a new IP address to OnCell, the host must have some way of
determining OnCell’s new IP address.

OnCell G3111/G3151-HSPA products help out by periodically reporting their IP address to the IP location
server, in case the IP has changed. The parameters shown below are used to utilize the Auto IP report
function. Once the OnCell Windows Driver Manager receives the Auto IP Report message, it will change the
IP address of the COM mapping entry for the OnCell G3111/G3151-HSPA whose LAN MAC address is
specified in the following MAC address field.

B-10
OnCell G3111/G3151-HSPA Series Software Installation/Configuration

9. The Serial Parameters tab in the following figure show the default settings when the OnCell
G3111/G3151-HSPA is powered on. However, the program can redefine the serial parameters to different
values after the program opens the port with Win32 API.

10. Click the Security tab to configure security settings. Select the Enable Data Encryption option to enable
data to be encrypted when transmitted over the COM ports. After selecting the encryption option, select the
Keep connection option to start encrypting COM port communications immediately without restarting the
COM ports. (If your application opens and closes COM ports frequently and the OnCell G3111/G3151-HSPA
is only for one host, you can enable this option to speed up the opening/closing time. However, this will
result in your host tying up the COM port so that other hosts cannot use it.) Select the Apply All Selected
Ports option to enable the security settings to be applied to all COM ports.

B-11
OnCell G3111/G3151-HSPA Series Software Installation/Configuration

11. To save the configuration to a text file, select Export from the COM Mapping menu. You will then be able
to import this configuration file to another host and use the same COM Mapping settings in the other host.

Moxa OnCell Linux Real TTY Driver

Basic Procedure
To map an OnCell G3111/G3151-HSPA serial port to a Linux host’s tty port, follow these instructions:

1. Set up the OnCell G3111/G3151-HSPA. After verifying that the IP configuration works and you can access
the OnCell G3111/G3151-HSPA (by using ping, telnet, etc.), configure the desired serial port on the OnCell
G3111/G3151-HSPA to Real COM mode.
2. Install the Linux Real TTY driver files on the host.
3. Map the OnCell serial port to the host’s tty port.

Hardware Setup
Before proceeding with the software installation, make sure you have completed the hardware installation.
Note that the default IP address for the LAN interface of OnCell G3111/G3151-HSPA is 192.168.127.254.

Note: After installing the hardware, you must configure the operation mode of the serial port on your OnCell
G3111/G3151-HSPA to Real COM mode

Installing Linux Real TTY Driver Files

1. Obtain the driver file from the included CD-ROM or the Moxa website, at http://www.moxa.com.
2. Log in to the console as a super user (root).
3. Execute cd / to go to the root directory.
4. Copy the driver file moxa_oncell_realtty.tgz to the / directory.
5. Execute tar xvfz moxa_oncell_realtty.tgz to extract all files into the system.

B-18
OnCell G3111/G3151-HSPA Series Software Installation/Configuration

6. Execute /tmp/oncell_realtty/mxinst.
For Red Hat AS/ES/WS and Fedora Core1, append an extra argument as follows:
# /tmp/oncell_realtty/mxinst SP1
The shell script will install the driver files automatically.

7. After installing the driver, you will be able to see several files in the /usr/lib/oncell_realtty/driver
folder:
> mxaddsvr (Add Server, mapping tty port)
> mxdelsvr (Delete Server, un-mapping tty port)
> mxloadsvr (Reload Server)
> mxmknod (Create device node/tty port)
> mxrmnod (Remove device node/tty port)
> mxuninst (Remove tty port and driver files)
At this point, you will be ready to map the OnCell serial port to the system tty port.

Mapping TTY Ports

Make sure that you set the operation mode of the desired OnCell G3111/G3151-HSPA serial port to Real COM
mode. After logging in as a super user, enter the directory /usr/lib/oncell_realtty/driver and then execute
mxaddsvr to map the target OnCell serial port to the host tty ports. The syntax of mxaddsvr is as follows:

mxaddsvr [OnCell IP Address] [Total Ports] ([Data port] [Cmd port])

The mxaddsvr command performs the following actions:

1. Modifies oncellreald.cf.
2. Creates tty ports in directory /dev with major & minor number configured in oncellreald.cf.
3. Restarts the driver.

Mapping tty ports automatically

To map tty ports automatically, you may execute mxaddsvr with just the IP address and number of ports, as
in the following example:

# cd /usr/lib/oncell_realtty/driver
# ./mxaddsvr 192.168.3.4 1

In this example, one tty port will be added, with IP 192.168.3.4, with data port 950 and command port 966.

Mapping tty ports manually

To map tty ports manually, you may execute mxaddsvr and manually specify the data and command ports, as
in the following example:

# cd /usr/lib/oncell_realtty/driver
# ./mxaddsvr 192.168.3.4 1 4001 966

In this example, one tty port will be added, with IP 192.168.3.4, with data port 4001 and command port 966.

B-19
OnCell G3111/G3151-HSPA Series Software Installation/Configuration

Removing Mapped TTY Ports

After logging in as root, enter the directory /usr/lib/oncell_realtty/driver and then execute mxdelsvr to
delete a server. The syntax of mxdelsvr is:

mxdelsvr [IP Address]

Example:

# cd /usr/lib/oncell_realtty/driver
# ./mxdelsvr 192.168.3.4

The following actions are performed when executing mxdelsvr:

1. Modify oncellreald.cf.
2. Remove the relevant tty ports in directory /dev.
3. Restart the driver.
If the IP address is not provided in the command line, the program will list the installed servers and total ports
on the screen. You will need to choose a server from the list for deletion.

Removing Linux Driver Files

A utility is included that will remove all driver files, mapped tty ports, and unload the driver. To do this, you only
need to enter the directory /usr/lib/oncell_realtty/driver, then execute mxuninst to uninstall the driver.
This program will perform the following actions:

1. Unload the driver.

2. Delete all files and directories in /usr/lib/moxa_oncell
3. Delete directory /usr/lib/moxa_oncell
4. Modify the system initializing script file.

Moxa OnCell UNIX Fixed TTY Driver

Installing the UNIX Driver

1. Log in to UNIX and create a directory for the Moxa TTY. To create a directory named /usr/etc, execute the
command:
# mkdir –p /usr/etc

2. Copy moxa_oncell_fixedtty.tar to the directory you created. If you created the /usr/etc directory
above, you would execute the following commands:
# cp moxa_oncell_fixedtty.tar /usr/etc
# cd /usr/etc

3. Extract the source files from the tar file by executing the command:
# tar xvf moxa_oncell_fixedtty.tar

The following files will be extracted:

4. Compile and Link

For SCO UNIX:
# make sco

For UnixWare 7:
# make svr5

For UnixWare 2.1.x, SVR4.2:

# make svr42

Configuring the UNIX Driver

Modify the configuration:

The configuration used by the oncellttyd program is defined in the text file oncellttyd.cf, which is in the
same directory that contains the program oncellttyd. You may use vi, or any text editor to modify the file, as
follows:

ttyp1 192.168.1.1 950

For more configuration information, view the file oncellttyd.cf, which contains detailed descriptions of the
various configuration parameters.

Note: The “Device Name” depends on the OS. See the Device Naming Rule section in README.TXT for more
information.

To start the oncellttyd daemon after system bootup, add an entry into /etc/inittab, with the tty name you
configured in oncellttyd.cf, as in the following example:

ts:2:respawn:/usr/etc/oncell_fixedtty/oncellttyd –t 1

Device naming rule

For UnixWare 7, UnixWare 2.1.x, and SVR4.2, use:

pts/[n]

For all other UNIX operating systems, use:

ttyp[n]

Starting moxattyd

Execute the command init q or reboot your UNIX operating system.

Adding an additional server

1. Modify the text file oncellttyd.cf to add an additional server. User may use vi or any text editor to modify
the file. For more configuration information, look at the file oncellttyd.cf, which contains detailed
descriptions of the various configuration parameters.
2. Find the process ID (PID) of the program oncellttyd.
# ps -ef | grep oncellttyd

3. Update configuration of oncellttyd program.

# kill -USR1 [PID]
(e.g., if oncellttyd PID = 404, kill -USR1 404)

This completes the process of adding an additional server.

D. RFC2217

This appendix explains how to set up the environment to use RFC-2217 mode. RFC2217 defines general COM
port control options based on the Telnet protocol and is used to allow the mapping of virtual COM ports to
network ports. Any third party driver that supports RFC-2217 can be used to implement the virtual COM port
on the OnCell G3111/G3151-HSPA. The installation is as follows:

1. In the OnCell G3111/G3151-HSPA console, set up the desired serial port’s operation mode as RFC2217
mode. By default, the first serial port on the OnCell G3111/G3151-HSPA is assigned TCP port 4001, the
second serial port is assigned TCP port 4002, and so on.

2. Download and install a third party driver that supports RFC-2217, such as Serial/IP COM Port Redirector
(from Tactical Software).
3. Using your third party’s configuration program, map a COM port to the OnCell G3111/G3151-HSPA’s IP
address and the serial port’s TCP port.
4. Try opening the COM port that you just mapped. If you are able to open it, then the mapping was successful,
and devices attached to the serial port on the OnCell G3111/G3151-HSPA may be treated as if they were
attached directly to the host computer.

E. Dynamic Domain Name Server

This appendix explains how to use the OnCell G3111/G3151-HSPA with DDNS. When the OnCell
G3111/G3151-HSPA receive its IP address from a DHCP (Dynamic Host Configuration Protocol) server, remote
servers will be unable to access it using a fixed IP address. With DDNS (Dynamic Domain Name Server), a
remote server can access the OnCell G3111/G3151-HSPA using its domain name instead of its IP address.

Overview
The following is a summary of the process:

1. The OnCell G3111/G3151-HSPA sends a request for an IP address to the DHCP server. At the same time, it
notifies the DHCP server of its desired server name (“OC3100” in the illustration) according to the option 12
standard.
2. The DHCP server replies with the IP address that is assigned to the OnCell G3111/G3151-HSPA, along with
the domain name (“moxa.com” in the illustration) and the IP addresses for the DNS server and gateway.
3. If the OnCell G3111/G3151-HSPA has authorization to update the DNS server, it will register its FQDN (Fully
Qualified Domain Name) with the DNS server. The OnCell G3111/G3151-HSPA’s FQDN will be in the format
server name.domain name (“OC3100.moxa.com” in the illustration).
4. If the OnCell G3111/G3151-HSPA is not authorized to update the DNS server, the DHCP server can be used
to update the DNS server. The DHCP server will register the DNS server with the PTR RR (the record of
request for a domain name with IP address).
OnCell G3111/G3151-HSPA Series Dynamic Domain Name Server

The above screenshot shows how DHCP can be set up to update the DNS.

Currently, the OnCell G3111/G3151-HSPA supports DNS service as provided by DynDNS. For detailed
information on this option, visit https://www.dyndns.com.

Configuration

DDNS (default=Disable): Use this field to enable or disable DDNS.

Server address (default=DynDns.org): Currently, DynDns.org is the only option available for Server address.

Host name: In this field, use the name that you created on www.dyndns.com. The OnCell G3111/G3151-HSPA
will update the DynDNS server with this host name.

Username: This is the user name used for update authentication.

Password: This is the password used for update authentication.

F. Well Known Port Numbers

In this appendix, we provide a list of well-known port numbers that may cause network problems if you set the
OnCell G3111/G3151-HSPA to one of these ports. Refer to RFC 1700 for well-known port numbers or to the
following introduction from the IANA:

The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and the Dynamic
and/or Private Ports.

The Well Known Ports range from 0 through 1023.

The Registered Ports range from 1024 through 49151.

The Dynamic and/or Private Ports range from 49152 through 65535.

The Well Known Ports are assigned by the IANA, and on most systems, can only be used by system processes
or by programs executed by privileged users. The following table shows famous port numbers among the listed
well-known port numbers. For more details, visit the IANA website at
http://www.iana.org/assignments/port-numbers.

G. Auto IP Report Protocol

OnCell Series provides several ways to configure Ethernet IP addresses. One of them is DHCP Client. When you
set up the OnCell to use DHCP Client to configure Ethernet IP addresses, it will automatically send a DHCP
request over the Ethernet to find the DHCP Server. And then the DHCP Server will send an available IP address
to the OnCell. The OnCell will use this IP address for a period of time after receiving it. But the OnCell will send
a DHCP request again to the DHCP Server. Once the DHCP Server realizes that this IP address is to be released
to other DHCP Client, the OnCell then will receive a different IP address. For this reason, users sometimes find
that the OnCell will use different IP addresses, not a fixed IP address.

In order to know what IP address the OnCell is using, you need to set up parameters in Network Settings via
Web browser. The figure below is the OnCell Web console configuration window. Enter the IP address and the
Port number of the PC that you want to send this information to.

H. GSM Alphabet

Standard SMS can contain 160 characters. However, the characters typed must be part of the so-called 7-bit
default alphabet as specified by GSM 3.38. As shown in the table below, this alphabet contains all ASCII
characters and some accented characters.

For example, u umlaut (ü) and e with grave (è) are in this set. Using any character not in this set will force the
SMS to be a Unicode SMS, in which case the length of the SMS will be limited to 70 characters.

Note that the following characters count as two characters: { } [ ] ~ | \ and the Euro symbol €. As you
can see in the table below, this is because the codes for these characters must be prefaced by the escape code
(0x1B).

The table below shows the 7-bit default alphabet as specified by GSM 03.38. The corresponding ISO-8859-1
decimal codes are shown in the rightmost column. Note that the euro sign (€) is also included.
