4.0 Hardware Connection

4.1 Network Configuration

The EasyIO-30P Bacnet controller can be connected via Ethernet (10/100 Base-T
using Bacnet IP and/or Bacnet Ethernet) or through RS485 serial connection (Bacnet
MSTP).

Figure 3: Network Configuration

4.2 RS485 Connection

RS485 connection must be terminated at both ends with termination resistor, typically
120Ohms. It is recommended to use shielded twisted pair wire (STP) for the wiring.
Lightning protection circuit is recommended to be installed at one end of the wiring.
The controller should be wired in daisy chain network topology as shown in Figure
5.0. If wire branch can be avoided (as shown in Figure 4.0), keep it as short as
possible, and never connect more than one device to the wire branch. Be careful if
single power supply is used for all connected RS485 device, make sure all devices are
having the same ground connection. Make sure you are connecting the same wire for
the same terminal position, all “H” terminals connected to the same wire.

4.3 Power Supply Connection

Both AC and DC can be used for EasyIO-30P controller. Refer to electrical
specification for the working range. In order to avoid damage on the controller
input/output devices and RS485 connection, use individual power supply for each
controller. If a single power supply is used, make sure controller power supplies are
connected with the same polarity.

4.6 Digital Input Connection

EasyIO-30P has eight general purpose non-isolated digital input connections. Figure
9.0 shows the typical connection usage of the EasyIO-30P digital input. The digital
inputs are NOT electrical isolated from the controller. Only dry contact devices are
allowed to connect to the digital input and the dry connection resistance (including the
wire resistance) should be less than 500 Ohms for active low condition and more than
900 Ohms for active high condition. The common connections (C) are shared among
the digital input.

Figure 9: Digital Input Connection

4.7 Digital Output Connection

EasyIO-30P has eight general purpose isolated digital output connections (relay
output). Each relay output able to drive up to 2A 30VDC load.

4.8 Open Collector Output Connection

EasyIO-30P has two Open Collector Output connections (1A-1B and 2A-2B). The
open collector output is an isolated PWM (Pulse Width Modulation) output. The
working frequency is from 0 to 500Hz with 50% duty cycle. Each output can drive up
to 1A load with maximum voltage 60V.

Figure 11: Open Collector Output Connection

4.9 Universal Input (Analog Input) Connection

EasyIO-30P has eight non-isolated universal inputs. The universal input can be
connected to three type of analog signal i.e. resistance, voltage and current transmitter
via hardware jumper and internal register settings:

a) Resistance – The working range of resistance is 0 – 30Kohms. If the input

is configured as Thermistor type, the system provides 8 customizable

temperature lookup tables for resistance to temperature translation. The

commonly used Thermistor like 10K, 10K with Shunt, 1K Balco and 1K
Platinum are all supported

b) Voltage – Two types of working range 0 – 5V and 0 – 10V. The minimum

input impedance of voltage input is 1 Mega Ohm.

c) Current – Two types of working ranges 0 – 20mA and 0 – 24mA. The

current input impedance is less than 25 Ohm.

Refer to Jumper Setting section for proper input type selection.

Figure 12: Universal Input Connection

4.10 Analog Output Connection

EasyIO-30P has four Analog Output connections. Each Analog Output can be
configured to drive voltage and current output via hardware jumper setting and
internal register settings. The working range for voltage is 0 – 10V, and for current
either 0 – 20mA or 4 – 20mA. For current transmitter, the circuit able to drive load
impedance up to 800 ohm which is ideal for long wire connection (up to 500 meter
wire length).

6.0 Bootloader
The EasyIO-30P bootloader is used to check firmware information and upgrade new
firmware to EasyIO-30P. There are two ways to connect to EasyIO-30P bootloader.

1) RS485 Serial port.

2) Ethernet port (WINSOCK – TCP/IP).

It is recommended to use WINSOCK as the firmware upload speed is much faster

than RS485 port.

To activate the EasyIO-30P bootloader function, press and hold the ‘Services’ button
while turning on the power, (or press and release the ‘Reset’ button with power online)
and wait until the ‘STS’ blinks at fast rate (at about 5Hz), release the ‘Service’ button.

RS485 Connection:
Connect the EasyIO-30P RS485 to PC serial port via RS485-RS232 converter, open
‘HyperTerminal’ program (or others terminal program) with the following settings:
1) Baud rate = 115200bps
2) Data bit = 8 bits
3) Stop bit = 1 bit
4) Parity = None
5) Flow Control = None

When connection is established, presses ‘ESC’ button the refresh the screen. The
HyperTerminal should show the login screen as indicate below. If not, press Esc key
to refresh to screen.

8.5 Web Port Binding

EasyIO-30P has built-in many function blocks for standalone capability. Port Binding
feature has been added in to enhance the standalone capability. Port Binding is
available for selected Binary Output and Analogue Output registers only. When a port
(or register) is bind to other register, its value cannot be changed directly. The Binary
Output registers can only be bind to Binary Input registers (digital binding) and the
Analogue Output registers can only be bind to Analogue Input registers (analog
binding). Use Conversion function block to convert between digital and analog value.

Direct Control disabled.

Thermostat Enable 1 is

10.0 Bacnet Change of Value (COV) Reporting

Bacnet Change of Value (COV) reporting allows a COV-client to subscribe with a
COV-server, on a permanent or temporary basis, to receive reports of some changes
of value of some referenced property based on fixed criteria.

EasyIO30P provides 30 COV subscriptions for all Bacnet objects except Device
object. The COV subscriptions are not stored in non-volatile memory, the COV-client
needs to re-subscribe in case of power recycle happen to EasyIO30P controller.

EasyIO30P only support SubscribeCOV services, therefore only Present_Value and

Status_Flags property can be monitored. COV increment only available to the
following objects:
1) Analog Input
2) Analog Output
3) Analog Value

whereby for Binary Input, Binary Output, Binary Value and Multistate Value, COV
monitors the changes of the Present_Value and Status_Flags properties.
