Commander Manual 5
 What is Commander?
Commander is the smaller of North’s building controllers, which also includes ObServer. The controllers
contain North’s interface technology, block-based programming language, and easy-to-use information
services. Commander can work as a stand-alone controller; linked with Commander Hub for easy remote
monitoring; or alongside other North controllers and display systems to create a larger control or
monitoring solution.

Interface Technology
Commander includes North’s interface
technology. Commander can access values
from thousands of different third-party
systems in a common way, using North
drivers. This ability allows Commander to
pass data between different systems and
enables different sub-systems within a
building to be fused together to form a
single, coherent system.

Programmable Control
ObVerse is North’s block-based programming language. It is available in all North controllers. Although it
is easy to use, it provides real flexibility during engineering, allowing the engineer to incorporate design
changes with minimal effort. Date and timer functions are standard, along with feedback control and
logic.

Information Services
Commander supports North’s standard protocol, allowing communications with other North products,
including powerful engineering tools and display software. Commander also generates and serves
standard HTML web pages automatically - these provide a consistent user display on all browsers,
including those on mobile devices. Commander can also monitor and inform users about alarm
conditions using email or SMS, for example.
The engineer can extend information services, if necessary, by using North’s driver technology: values
from within Commander can be made available to, say, BACnet and Modbus devices.
Commander can link to Commander Hub, the cloud-based meeting place for Commanders, their owners,
their installers, and their service providers. These people can then access Commander’s data from
anywhere, viewing historical data and adjusting values. Events can be emailed to the relevant people.

Commander Manual 6
 Typical Use
Commander’s powerful feature list means it can perform a wide range of tasks. The following are typical
applications…

Single-device Integration of Systems

Creating an interface between two or more systems is easy
with Commander (Fig. 1). Interlocking an air-conditioning
system with an underfloor heating system is a common
problem, although the possibilities are endless.

System System

Fig. 1 Integration

Building-wide Management System

Connecting different systems, in different locations, to a
common LAN (usually an intranet or VPN) allows users to
manage these systems using a common interface from
anywhere on the LAN and adjust settings as necessary.

Remote Management System

Commander can be part of a remote management system
that connects different systems in different buildings and
provides information back to a central display. The central System

 Quick Start
Mount Commander
Secure your Commander in its final position, as far away from electrical noise as possible.
If you are mounting Commander directly on to a wall or panel, use the chassis as a template to mark and
drill holes. Screw the Commander securely to the even surface using the mounting holes.
If using the optional DIN-rail mounting kit, order code MISC\DINKIT, attach the clips to the back of the
Commander using the bolts provided. Tighten the bolts as much as necessary so the clip retains its
shape. Clip the Commander on to standard symmetrical ‘top hat’ type (TS35) DIN rail.
Leave a clearance of at least 10mm around Commander, with 90mm minimum at the cable connection
edge.

Insert Battery and Set Switches

Detach Commander’s lid by removing the two screws and sliding off.
Place the supplied battery into the holder, making sure to insert it the correct way around, and secure
with the supplied clip. Refer to the Internal Battery section for more details.
Ensure FACTORY and PROGRAM switches are OFF. Set DEFAULTIP switch ON to use the default IP address
of 192.168.192.167, or OFF to use a dynamic IP address from a DHCP server. Refer to the Internal Switches
section for more details.
Re-attach Commander’s lid to protect internal components.

Connect to LAN
Connect Commander to a 10Base-T compatible Ethernet switch using CAT-5 cable. Commander will
detect whether a patch or cross-over cable is used and work with either. Refer to the LAN Port section for
more details.

Apply Power
Commander’s power connector is polarity independent. Use a 12 to 24V, AC or DC, power supply rated at
3VA. We recommend using a good quality regulated DC power supply, for example 12V DC providing
500mA per Commander. Refer to the Power section for more details.
The Commander MODE LED will illuminate green to indicate a healthy power. Refer to the LEDs section
for more details.

Setup Commander using North Engineering software

Install North Engineering software onto a PC on the LAN if necessary. It is available from
www.northbt.com
Run the Start Engineering application.
If you are connecting to a network of devices, select North IP Devices then press Scan to rescan the LAN
for the new Commander. The Commander should appear in the list – with a label that includes its serial
number. If you are connecting your PC directly to Commander at its default IP address, select
Commander.
Refer to the Commander Tutorial document for more details, including full walk-throughs of all the main
features.

Fig. 7 Internal battery and switches
Commander measures the voltage supplied
from its battery and can send alarms when this
becomes too low. You may wish to replace the battery after 10 years, regardless of whether battery has
been required or not.

Replacing the battery

To replace a low battery, keep the Commander powered when you replace the battery, or you will
inadvertently load the default configuration.
Battery type: 1/2 AA size, 3.6V, 1.2Ah, Lithium Thionyl Chloride (Li-SOCI2), non-rechargeable.
Compatible batteries include: EVE ER14250, Saft LS14250, Tadiran SL-350/S.
Visit northbt.link/battery to search for compatible batteries.

Safety
Caution: loose lithium batteries can cause fires, protect from short circuit.

Commander Manual 11
 Internal Switches
Remove the lid to access Commander’s switches (Fig. 7).
The DEFAULTIP switch selects whether Commander uses the default or an assigned IP address. When set
ON, Commander is set to use the default IP address of 192.168.192.167. This is useful if you do not know
the assigned IP address of Commander. When set OFF, Commander uses the DHCP or engineer assigned
IP address. Refer to the LAN Port Setup section on how to assign an IP address. When the switch is
changed, Commander restarts.
It also enables other services – for example, Telnet. Be cautious therefore when deciding to leave a
Commander in DEFAULTIP mode. Refer to Appendix C for a full list of services enabled.
When the PROGRAM switch is set ON (and Commander restarted), it enables the installing of new
firmware into Commander’s flash memory.
The FACTORY switch should always be set OFF.

Memory
Commander has 8MB of flash memory, which holds its main operating firmware and driver firmware,
along with a default configuration. Refer to the Firmware and Default Configuration sections for details on
how this is utilised.
The main operating and driver firmware can be updated to the latest version, and new drivers added.
Follow the guide in the Updating Commander’s Firmware section.
Commander also has 4MB of RAM, which it uses to hold all configurable settings – this is battery-backed
to maintain the memory over a power-failure. A fresh battery will maintain the memory contents for
several years.

Interface Licences
North supply Commander with a certain number of interface licences, which control the number of
interfaces that can be used at a time. Each interface usually requires one interface licence before it will
start, although certain drivers require zero licences.
It is possible to upgrade the number of interface licences available within a Commander. Simply call
North support while you are on site to activate a new licence.
Refer to the Interfacing Commander to other Systems section for more details.

Commander Manual 12
 Firmware
Commander’s operation, and all of its power and flexibility, is controlled by firmware stored in its flash
memory.

Main Firmware
The main operating features are provided in firmware. This firmware is loaded into Commander during
production and can be updated if required.
The main operating features evolve over time as newer ideas are incorporated, but contain the following
areas:
• General platform information, such as firmware versions
• LAN port setup, including IP addressing and time synchronisation
• Real-time clock and time zone, including daylight saving
• Interfacing to other systems
• Transferring values between systems
• Database of essential values
• Controlling using time and date
• ObVerse cause-and-effect strategy
• Alarm handling, including filtering, delivery, and audit trails
• Communicating with other North IP devices
• Security server
• Telnet server
• Web server

Interface Driver Firmware

Interface drivers are provided in individual firmware files, to simplify updating. The most popular
interface drivers are loaded into Commander during production (see Appendix B). Less-used interface
driver firmware can be downloaded as required. Interface drivers can be updated as newer versions are
produced.
Popular interface drivers include:
• Modbus – including Modbus over TCP/IP and serial line protocols
• BACnet/IP – as both a client and a server
• Zip – to communicate and control a North Zip network
• JSON – an API for third-party software and web services
• Echelon LonWorks – for accessing LonWorks compatible and LonMark certified devices
• Advanced – one of many available fire panel interfaces
• Mitsubishi – one of many air-conditioning interfaces
• DALI – one of many lighting interfaces.
For the latest list of drivers available for Commander, visit northbt.link/drivers.

Commander Manual 13
 Functional Organisation
The different areas of function within Commander (or any other North product) are organised, and
therefore engineered, in the same way using objects.
This object system, which North have used in products for many years, is extremely simple to
understand, and yet gives a flexible, extendable system.
The object system has two simple rules:
• Each device appears as an object
• Each object can either contain other sub-objects, or have a value that can read (and usually set)
Commander appears on the LAN as an object; it contains sub-objects that represent the sub-functions
within Commander; each of these contains sub-objects representing sub-functions; and so on until we
get to sub-objects that have values, which can be viewed and possibly adjusted.

Functions
Functions within Commander are represented by container objects. A container object can either have a
pre-determined list of sub-objects (called a fixed container object), or can have a variable list of sub-
objects (called a variable container object).
North’s object engineering software shows the contents of an object, and allows the engineer to navigate
up, down and across these container objects. It also allows the engineer to scan and find the sub-objects
within any variable container object.
For example, Commander is a variable container object with its contents changing as interfaces are
started and stopped.

Settings
Settings within Commander are represented using value objects. The value of an object can be viewed by
engineering software or by other devices; some value objects can also have their value adjusted.
North’s object engineering software shows the current values of these objects, and allows the engineer to
make changes to objects that are adjustable.
For example, Commander’s label is a value object that can be viewed and adjusted.

Organisation of this Manual

The following chapters in this manual describe the functional areas within Commander. These areas
appear as sub-objects of Commander within the object engineering software, ObView.
Refer to the Commander Tutorial for more help on using the object engineering software to engineer
Commander, including full examples.
The final chapter, Object Specifications, details the contents to each of Commander’s container objects. It
lists each of the fixed and variable container objects and describes the type and attributes of each value
object.

Commander Manual 14
 Platform Information
The Platform Information area provides general information about Commander.

Switch Settings
It is possible to view the mode specified by Commander’s switches, although objects are read-only.
Because the values are available as objects, they can be used by the engineer to affect other things, such
as enabling cause-and-effect strategy, or enabling security for certain users.

Battery Level
The state of Commander’s battery is available as an object. Commander will also send a battery status
alarm when the battery voltage reduces to a low level (3V) or very low level (2V). If necessary, the battery
state can be transferred to other external devices, such as lamps and sounders.

Default Configuration
Commander’s engineered settings are held in battery-backed memory. If the battery has expired when
the external power is lost, this configuration is lost.
Commander’s current configuration can be saved to permanent flash memory, so that if the settings are
lost, the default configuration can be loaded.
This feature can be used in several ways:
• As a failsafe, if the battery and power fail simultaneously
• As a pre-configuration mechanism, enabling a user to load a standard configuration.

Reset/Restart Information
Commander holds information about the last restart to occur, including the assumed cause. This
information is sometimes useful when solving problems.

Software Versions
Commander’s firmware is made up from a collection of different modules. The software version and
build date for each module is available, again to help when solving problems.

Software Cloud Update

If Commander has access to the Internet (and therefore to North’s cloud services) it can be instructed to
check it is running the latest firmware. It will check the installed system and driver software against the
latest available versions, and update them if necessary.

Commander Manual 15
 Debug Recording
Commander can send information to an unused COM port to assist with debugging. The North support
team may request that this information is captured.
A set of flags specify which debug information is recorded:
Information – general start-up information
Objects – request/reply messages between modules
COMs – bytes being sent and received on COM ports
Network – IP events, including ARP and DHCP
Internal Comms – fast request/reply messages between internal modules
An ASCII terminal, or PC running terminal software, is needed to receive the debug information. The
terminal needs to be set to 38400 baud, no parity, 8 data-bits, 1 stop-bit, and no hardware flow control.
An RS232 null-modem cable is required to connect the terminal software to Commander.

Commander Manual 16
 LAN Port Setup
The LAN Port area allows the set-up of Commander’s LAN port. The most important value is
Commander’s IP address, which allows other devices, including engineering software, to access
Commander from elsewhere on the LAN.
There are three ways of assigning Commander with an IP address to use:
Default – a predetermined IP address, controlled by a hardware switch within Commander
Static – set to an engineer-assigned fixed address
Dynamic – set to an address assigned dynamically by a DHCP server [Factory setting]

Whichever way is used, Commander’s current IP address is available within a read-only object.

Default IP Addressing
Setting the DEFAULTIP internal switch to ON, restarts Commander to work at the default IP address of
192.168.192.167 with a subnet mask of 255.255.255.0. This is useful for quick engineering, and if the
Commander’s IP address is unknown. Default IP mode overrides other IP address configuration, and
enables the DHCP server. This method is not usually compatible with a real LAN, but more for connecting
directly from Engineering PC to Commander.

Static IP Addressing
Configuring an IP address and subnet mask assigns Commander to use that IP address – you can also
configure a gateway, DNS server, and time server addresses. This is the usual way of configuring the IP
address, as users and other devices usually need to know where Commander is.

Dynamic DHCP Addressing

Configuring an IP address of ‘0.0.0.0’ instructs Commander to request its IP settings from the LAN’s DHCP
server – the server normally also supplies DNS and NTP server addresses. Dynamic addressing is simpler
that static addressing, but the IP address given by the DHCP server to Commander may change after a
period.
This is the default setting. If you wish to use Commander in this way, please ensure that the DHCP server
will reserve addresses, and not re-assign them to other devices. The MAC address is listed to assist in
creating a DHCP reservation.

DNS Server Address

Commander sometimes needs access to a DNS server to resolve fully qualified domain names (FQDN). It
is usual for the DHCP server to provide the server’s IP address, but otherwise the engineer can configure
it using this object.
If no DNS address is specified, 1.1.1.1 is used if possible.

Time Server Address

Commander can request time information from an NTP server, but again needs to know the server’s
address. It is usual for the DHCP server to provide this, but otherwise the engineer can configure it.
If no NTP server address is supplied, Commander will try to contact ‘pool.ntp.org’ for a valid NTP server if
possible.

Commander Manual 17
 Real-time Clock and Time Zone
Commander contains a real-time clock, time-zone information, as well as daylight saving offsets.
Commander can use all of these to determine local time.

Coordinated Universal Time

Commander contains a hardware real-time clock (RTC). The internal battery retains settings when the
Commander is powered-off. This clock holds Coordinated Universal Time (UTC).
If the Commander has access to an NTP time server, it will automatically correct its clock. Commander
requests the time from the NTP server every 4 hours, and if the response is acceptable, the real-time
clock is adjusted (if out by more than 2 seconds).

Local Time
Commander calculates local time by applying a local time offset to UTC time (as well as any daylight-
saving offset). By default, Commander’s local time offset is zero, which is correct for the United Kingdom
and Ireland. In mainland Europe, the local time offset should be set to +1 hour.
If the local time is adjusted manually, Commander will automatically convert the value to UTC before
writing to the real-time clock.

Daylight Saving Time

Commander’s daylight-saving table is set during production with 10 years of dates and offsets suitable
for use within the European Union. If used outside of this area, the dates and offsets within the table
should be set as necessary.

Commander Manual 18
 Interfacing Commander to other Systems
One of Commander’s strengths is its ability to interface to several systems, including those from other
manufacturers. Drivers are the software convertors that allow interfaces to work.
The driver required for a particular interface is selected from those installed in Commander. Commander
starts these interfaces when they are specified, and whenever Commander is restarted. Drivers can be
stopped, if they are no longer needed.

Started Interfaces
Commander allows up to four interfaces to be started and used at the same time, although interface
licences may limit this.

Installed Drivers
The list of drivers currently installed within the Commander can be viewed – and the names copied to the
current interface list to start an interface using a particular driver. The same driver can be used on several
interfaces concurrently. For example, Commander can start interfaces to two separate Zip systems, each
with 16 Zip modules.
Commander has certain drivers pre-installed in the factory. For a list of these, see Appendix B – Factory
Installed Drivers.
Other drivers can be installed at any time. For details on how to do this, see Updating Commander's
Firmware.

Interface Licences
Each Commander is supplied with a certain number of interface licences. It is possible to add more
licences on site, although a phone call is required to check/verify settings.
Call North support on +44 (0) 1273 694422 for more help with adding more licences.
Order Codes for Commander are as follows:

Commander Manual 19
 Transferring Values
Transferring values from one place to another is the simplest form of integration. Commander supports
this with Data Transfers – where each transfer reads from one place and then writes to another.
Commander supports up to 500 Data Transfers.
Transfers are processed sequentially. Each transfer contains a source object reference, a source read
rate, the last value read, a destination object reference, and a destination write rate.
Commander’s object system means that any value available from Commander, including configuration
objects and other attached systems, can be used with transfers.

Reading the Value

The source read rate should be configured to suit the type of value being transferred. For example, room
temperatures are typically read every minute or so, and operating set points read every 15 minutes.
Setting the source read rate to ‘as soon as possible’ (ASAP) instructs Commander to read the value every
time the transfer is processed – if all transfers have a read rate set to ASAP, the reading occurs
sequentially.
Remember to consider the time needed to read values, because they do not occur instantaneously. If it
takes 1 second to read a value from an external system, then it will take 100 seconds to read 100 values.
Even if you specify the 100 values read every minute, the best that could occur would be every 100
seconds.

Writing the Value

Rather than read-then-write continuously, each transfer will usually only write the value to the
destination object when the value changes – called change-of-value (COV) writing. This eases the
workload within the destination system and saves time and effort within Commander.
It is also possible, to have the transfer perform a background write periodically. Occasionally it is useful
to have the last value re-written in this way – for instance, if a system forgets values after a power failure,
or if a local adjustment needs to be reset after a certain time.
Remember COV writes always happen, so consider if a background write is needed and how frequently it
needs to occur. Writing the value takes precedence over reading, so set the write rate to a longer time
than the read rate. A background write only usually needs to occur every few hours.

Transfer Tasks
By default, Commander works through the list of transfers sequentially – after finishing transfer 1, it
starts transfer 2, and so on, until it reaches the last transfer, after which it starts work on transfer 1 again.
This is simple to understand but can be quite slow. If values are from several different systems, it is
possible to allow the Data Transfer system to try to perform two or more transfers simultaneously.
However, this feature should be used with care, and should be fully tested before handover, because if
several tasks are reading from or writing to the same system, overloading of the system’s
communications can occur.

Commander Manual 20
 Essential Data
Several different modules within Commander need access to a database of values – called Essential Data.
Essential Data allows the engineer to configure a list of values that other Commander modules can then
distribute – as web pages, as BACnet points, as Modbus points, on Zip displays…

Structure
Essential Data consists of a list of configurable pages, each of which has a list of configurable objects. In
total, 640 database objects are available. The engineer may choose from a mix of page and object counts:
40 pages of 16 objects (default), 64 pages of 10 objects, 20 pages of 32 objects, or 10 pages of 64 objects.
Older versions of Commander only support 30 pages of 16 objects (total 480 objects).
An Extra Data driver is also available to extend the number of database values available within
Commander.

Pages
The engineer configures a label for each page. Other Commander modules use the label when displaying
the value from within the database – if a page has no label, then the page does not appear in label-based
hierarchical views, such as those available as web pages.
Each page has a remote object prefix. This allows objects within the page to reference remote data
relative to this prefix. When in use, if any object in the page fails to read its remote object, Essential Data
assumes all the objects will fail, and therefore saves time and effort. It also allows easier copying of pages
when several devices of one type are used.

Objects
For each object within a page, the engineer configures a label. The label determines whether the object
appears – if an object has no label, the object does not appear in label-based hierarchical views.
The engineer configures the value type for an object. The type determines whether a value is made
available via a particular protocol – for example, profile objects are not made available over the Modbus
protocol. The type also controls the appearance of the value on hierarchical views, including when the
user adjusts the value.
Type Use Example
Text Text string of ASCII characters Kingston Lane
NoYes Binary state: 0 or 1 meaning No or Yes 1 (means Yes)
OffOn Binary state: 0 or 1 meaning Off or On 0 (means Off)
Number Integer, positive or negative -12300
Float Floating-point value, with decimal places 21.54
Times List of on-off times 08:30-12:00,13:00-17:30
DateTime A moment in time 25/12/15|12:30
Date A particular day 01/01/19
ENum A number representing something 3 (means Automatic)
Profile List of time-value changes 09:00=21,12:00=20,18:00=19

Commander Manual 21
 Value Reading and Writing
The engineer can configure the database object to read periodically from, or write periodically to, any
object accessible to Commander. This allows slow-access data to be collected and ready for speedy
delivery when needed.
As a new value is read, the object also recalculates the alarms state, sends alarm messages if necessary,
and logs the value.
Commander considers each object in a linear fashion, beginning with the first object on the first page. If it
is time to read (or write) the value, this is started; if not, the object is passed over. When the final object
has been checked, Commander starts from the first object again.
If all objects are set to read ASAP (as soon as possible), Commander performs each in turn. If it takes one
second to read an object, and there are five hundred objects to be read, the whole process will take five
hundred seconds. Please consider the read rate of objects, allowing time for the object to perform its
remote action.

Adjustability
By enabling adjustability, along with configuring value high and low limits, the engineer can control
whether the user can modify the value of an item – and if this occurs, the value will be written to the
associated object.

Alarm Monitoring
When a value is updated, it is compared against the value high and low limits, and an alarm message
generated as necessary if its alarm state changes.

Value Logging
If necessary, Essential Data can log the value periodically, to create a history of the value over time. Other
devices can access the data log.
Essential Data uses the configured log rate to sample the value – if the log rate is set to 15 minutes, one
day will use 96 readings.
A total of 40 objects can have logging enabled.
If the value has not changed from the last sample, then rather than waste sample space, the log records
start-and-end sample times to save space. Using this method, 15 minute sampling will use a maximum of
96 readings per day, but could be considerably less if, for example, the value is an alarm state.

Commander Hub
If the link to Commander Hub is enabled, values from Essential Data are sent to Commander Hub, where
all values are recorded. Historical data can be viewed, and adjustable objects may be changed via the
Commander Hub web pages at www.cmdrhub.com.

Commander Manual 22
 Controlling using Time and Date
Timers allow users to control when things happen in the day, and when they do not. Using timers can
save energy, while keeping the occupants happy. Commander supports time control using the calendar,
timers and profilers within it’s Time Control area.
Commander’s single calendar determines today’s day-type. Today’s day-type is used by 20 timers to
determine which of their on-off time-lists to use, and by 20 profilers to determine which of their time-
value profiles to use.

Calendar
Commander supports 10 different day-types: one of them is an off day-type, leaving nine to configure.
They are numbered 0 (off), and 1-9.
If you have a centralised calendar elsewhere on the system, Commander can request the day-type from
this – in which case you need to specify the object reference of the current day-type in the central
calendar.
If you are calculating the day-type in Commander, it works in the following way. The calendar determines
whether today’s date is an exception date – if it is, then that exception day-type is used; otherwise the
day-type of the standard day-of-week is used.
The calendar re-calculates the day-type every minute, based on the day-types and the exception dates.
Any North device that can access Commander’s objects can also access the calendar objects. The
Calendar is also available via the Web Server.

Timers
Commander uses timers to control off/on processes. Each timer produces an off or an on state, which can
be accessed by other tasks (Fig. 8).
Each timer has a time-list for each of the Timer
On/Off
possible day-types and uses that time-list on
Timer 1
days that have that day-type. A time-list is a Today’s
Day-type
list of on-off time-periods. The timer re- Timer 2
Calendar
calculates the state of the timer every minute. Timer 3

Any North IP device can access the Timers.

They are also available to view and edit via the
Timer 20
Web Server.
Fig. 8 Timers

Profilers
Commander uses profilers to control a variable value throughout the day.
Each profiler has a list of profiles, one for each possible day-type, and uses that profile on days that have
that day-type. Each profile is a list of time-value pairs, each pair representing a change-point. When the
current time matches a change-point time, the value is set to that of the change-point. The value can also
be set by other tasks: the value then acts as a temporary value, until the next change-point occurs.

Commander Manual 23
 ObVerse Cause-and-Effect Strategy
Sometimes you need to do more than simply transfer a value from one object to another – you need to
calculate something, delay something, or perform a more complex function on a value. North provides
this flexibility with ObVerse, a cause-and-effect programming language.
ObVerse consists of a range of modules. The engineer selects modules and links them together to
perform a desired strategy.
ObVerse strategy runs in an ObVerse processor within a device.
ObVerse processors come in two types:
• Standard Processor – with logic, maths, and control modules
• Advanced Processor – with the same features found in a standard processor plus extended maths
and logic, display, application execution, directory and file services, and user-defined modules.
Commander has two ObVerse standard processors.
ObVerse strategy is made up from properties, modules and comments.

Properties
ObVerse properties are containers for storing data values. They can carry a value from one module to
another, or between the processor and other functions within Commander.
Properties have a data type, to define the type of value they hold – like a number or a text string.
Properties sometimes hold values passing only between modules in the same processor. In ObVerse, we
call these private properties, as their value is private to the processor.
Properties sometimes hold values passing between the processor a function within Commander. In
ObVerse, we call these public properties, as their value is publicly available as an object.

Modules
Modules calculate values. They take one or more inputs and calculate one or more outputs.
Different modules are available to perform different operations. The range of modules supported
depends on the processor.
In Commander’s ObVerse standard processor, modules perform the following types of operation: Maths,
Logic, Control, Timers, System, and Object.

Editing ObVerse
You can create and edit ObVerse strategy using North’s ObvEditor application, installed as part of the
ObSys software. ObvEditor provides drag-and-drop graphical editing of ObVerse, uploading and
downloading of ObVerse strategy, and run-time monitoring of the strategy within the processor.

For further information on ObVerse in Commander, including properties and modules, refer to the
ObVerse Manual – Standard Processor.

Commander Manual 24
 Alarm Basics
As well as responding to object requests, Commander can process alarm messages – messages that
contain text information about events that have occurred.
Different users demand a wide variety of alarm processing – ranging from simple histories of alarms, to
lists of critical events that require user acknowledgement, to sending messages to mobiles phones or by
email.

Format
All North-format alarms are text-based, and have the following fields:
System and Point – identity of the system, device, and point that has changed
Condition – condition that the point has changed to
Priority – importance of the notification, between 1 (most) and 9 (least)
Date & Time – date and time that the condition changed
Refer to Object Specifications section for details of alarms sent by each module.

Alarm Delivery
All alarms arriving or being produced by Commander are passed into the Alarm Delivery area. Its role is to
distribute copies of the alarm to other alarm processing destinations, depending on the value of the
alarm fields.
Commander’s alarm delivery supports up to 16 destinations.
Commander has two built-in alarm processing destinations: Alarm History and Alarm Emailer. Other
destinations are available within other North devices and can appear within drivers and external systems
as interfaces are started.

Filtering Delivery
Besides having a destination enable, alarms can be filtered, so that only alarms with a priority in a certain
range are sent to a destination. This allows only the relevant alarms to be sent to certain destinations.
Filtering can also cover text matching and not-matching, to force alarms from particular systems to be
sent only to one destination, for example, while all other alarms are sent to a different destination.

Delivery to any one of a Group of Destinations

Sometimes users may need alarms sending to any of several destinations. For example, alarms must be
sent to any one of a range of on-call users (depending upon which has their PC running).
Commander supports each destination being a member of the any group, an indication that when one
destination accepts the alarm, it does not send to any of the other members of the any group.

History of Alarms
Sometimes, all that is required is a list of the latest alarms. Alarm history can act as an audit trail or can
be viewed more regularly to check on new alarm conditions. However, no user action is necessary, and as
new alarms occur, old alarms are lost. Commander’s alarm history holds the last 100 alarms.
If the link to Commander Hub is enabled, these alarms are sent to Commander Hub, where they are
stored.

Commander Manual 25
 Emailing Alarms
Some users want important alarms and event messages delivered directly to their inbox. Commander
has alarm emailing facilities to do this.
Commander’s alarm emailer supports six destination groups. Each group has its own filtering options, so
only alarms from a predetermined system are emailed to the group’s recipients, and an option to send in
a text-only or friendlier HTML format. A group supports up to five email address recipients.
The Alarm Emailer can connect to an SMTP relay server that supports authentication, but not to a server
that requires encryption. You can typically connect to an SMTP relay server on your local network (e.g.
Windows IIS SMTP Server), from your Internet service provider (e.g. BT Internet, Virgin Media), or from a
paid SMTP service provider (e.g. smtp2go.com, authsmtp.com, serversmtp.com, etc.).
SMTP relay servers that require TLS encryption (e.g. Gmail, Outlook, Office 365, AWS SES, etc.) are not
directly supported. To access a service requiring TLS, use an SMTP proxy such as Windows IIS SMTP
Server or Stunnel.

Fig. 9 Email from Commander’s alarm emailer

If the link to Commander Hub is enabled, use Commander Hub to email notifications of new events.

Alternative Alarm Destinations

By adding more interfaces, it is possible to add more ways of dealing with alarms, these include the
following:
Driver Use
AlarmStore Alarm Lists needing user acknowledgement, and archiving to CSV file (ObSys only)
AlmSet Convert alarm text to an object write
AlmXlate Translate alarm text
ESPA444 Pager support
GSMSMS SMS messages to mobile phones, via a GSM modem
Printer Print alarms to a serial printer

Commander Manual 26
 Communicating with other North IP Devices
All the North devices that support Ethernet also support the North IP protocol – Commander and ObSys.
The North IP protocol allows the devices to communicate efficiently using objects.

Key Security
It is easiest to allow all North devices on a network to communicate openly. However, it is possible to add
an authentication key to a device. This will stop other devices being able to communicate with it, unless
they also know the device’s authentication key. Each device could have a unique key – so Device A may
be able to request values from Device B, but not vice versa.

Checking Communications
It is possible to configure Commander to check that other North IP devices are still available and
communicating and generate alarm messages when they are not.

DEFAULTIP Switch
When DEFAULTIP switch is set ON, the Local Encryption Key is disabled. This enables an engineer to
access the Commander regardless of this security setting (as long as they have physical access to the
Commander).

Commander Manual 27
 Security Server
When Commander is connected to a network, the engineer must consider security – to control who can
and who cannot view and modify values, and who can engineer Commander itself.
Although it is possible to enable and disable certain engineering functions using the DEFAULTIP switch,
this is quite restricted.
North products, including Commander, that require user authentication have access to a central user
database that holds user information. Remote doors could use this, for example, to ask the central user
database for authentication when a user requires access.
Commander has Security Server, its own user database – it holds information, including privilege levels,
for different users.
Commander’s Security Server can support up to 400 users.
It is possible for a task within Commander to use a security server elsewhere in the system – for example
in a different Commander or within a PC running ObSys.

User Information
Besides a name, each user has a user ID (or card) and a password – together these form a coded token. It
is the coded token that is passed around a system – the password is never seen.
Each user is given eight privilege levels, one for each of eight different areas. The privilege level is in the
range 0 (no security clearance) to 7 (maximum clearance).
Individual users can also be enabled or disabled and can be limited to access between certain dates –it is
possible to see the last date that a security clearance was requested for the user.

Groups
Each user can be a member of up to three groups. Each group has a list of privilege levels, which act as a
base level for users that are a member of the group. This allows a whole group of users to be controlled
quickly and easily.
When groups are used, a user is enabled when any of the groups they are a member of is enabled (and
the user is enabled).
The user’s privilege level in a particular area is the highest level specified in that area from the individual
user information and from any group they are a member of

Use by other Tasks

A task that requires security clearance will have one or more access security objects. Each access security
object has a two-digit value, which controls access to a particular feature – such as adjusting a value or
viewing a page.
The two-digit value is made up of the area digit (1-8), followed by the minimum privilege level (1-7). The
user must have a privilege value equal to (or greater than) that specified, in the area specified, before the
task will allow access to the feature.
For example, if the minimum privilege level is ‘6’ in area ‘2’, then the two-digit value is ‘26’. If the value is
set to ‘00’, then no security checks are needed.

Commander Manual 28
 When the user wants to access the protected feature, the following occurs:
• The task requests identification from the user: this may be done by asking for a name and
password; or by scanning a security ID card
• The task encodes the identification, and requests the privilege levels for the user with that
identification from the Security Server
• The task receives the eight privilege levels from the server
• The task checks whether the user’s privilege level in an area is sufficient to allow access, and if so
will grant access
• The task may send an alarm message, indicating whether the user was allowed, or whether the ID
was not recognised.

Commander Manual 29
 Web Server
Commander’s local web server builds simple responsive html pages which the user can view in any
modern browser, including those on mobile devices ( Fig. 10).
The web server creates a website automatically, with pages in the following areas:
Overview – summary information
Values – view and adjust values from Essential Values
Events – view events from Alarm History
Device information – hardware, network, Commander Hub, and firmware information.
All pages update their information automatically while the user is active.
If restricted access is required, enable user sign-in or disable the web server completely.
Commander’s web server is ideal for local access when an Internet connection is not available. We
recommend enabling the link to Commander Hub, which provides remote access using North’s cloud-
based services.

Fig. 10 Page from Commander’s web server

Overview Page
Commander’s overview page highlights areas within Commander that need more investigation: values,
events, or the device itself.
Add links to external resources that may be useful to the end user – a web page, telephone number, or
email address.
When Commander’s DEFAULTIP switch is set ON, or Commander was powered-on in the last 5 minutes
with the PROGRAM switch ON, then Commander Hub and Network settings can be changed. This is useful
if someone needs to change the IP address of Commander and has no access to object-engineering
software.

Commander Manual 30
 Values Page
View Values from Essential Data, presented using the same page/value structure. Click on a value to view
it and, if it is adjustable, change the value.
Any pages with the same name will be merged together. Some Markdown formatting is supported for
text labels, including **bold** and *italic*.
Download all values in a comma-separated value (csv) file using the ‘Export data’ option.

Events Page
A single list shows all alarm events stored in Alarm History.
Download all events in a comma-separated value (csv) file using the ‘Export data’ option.

Device Information Page

Other information from Commander that may be useful to different users, including:
Device hardware – serial number, default configuration, battery state, and program switch
Network – active IP, subnet, and MAC
Date and time – local date & time
Commander Hub – link enabled and status
Last restart – time since restart, reason, and total restarts
System firmware – build versions
Interfaces – list of interfaces started, driver version, and state of connection to external system.

Security Settings
It is possible to specify whether users must sign-in before they can view or adjust values on the website.
User authentication is provided by the Security Server.
If users are not required to sign-in, set the default access privilege levels for requests originating from the
local network and remote networks.

DEFAULTIP Switch
When DEFAULTIP switch is set ON, the web server is enabled and security is disabled.

Commander Manual 31
 Commander Hub
Commander Hub is a meeting place for Commanders, their installers, their owners, and their service
companies. These people can then access Commander’s data securely from anywhere, viewing historical
data and adjusting values. Events can be emailed to relevant people.

Data Collection
Commander continually monitors and records any changes to:
• Values collected by Essential Data
• Alarm events received by Alarm History
• Device information
Then, typically every 5 minutes, it encrypts and transfers these changes to Commander Hub, where they
are stored.

Keeping it Secure
Data is encrypted from beginning to end, keeping it secure.
Commander encrypts data using the Advanced Encryption Standard (AES) before sending to Commander
Hub. The data stays encrypted when it is stored and is decrypted when an authorised user requests it.
Commander Hub serves web content securely using Transport Layer Security (TLS) to a browser.

High Availability Servers

Commander Hub has redundant servers to increase reliability. Commander can send the AES encrypted
data to either. Each server shares received encrypted data with the other, naturally creating a data
backup. The servers are located in different physical places and use different service providers within the
UK.

Easy to Connect
Commander is responsible for sending data to Commander Hub. It uses standard protocols, so most
networks require no firewall modification. Data requests are always outgoing, so no additional PCs, port
forwarding, complex VPNs, or fixed IP addresses are needed on the network.
If no Internet connection is available during install, use a low-cost 4G/5G LTE gateway with a simple data
plan.

My Hub
Connect to Commander Hub using any modern browser at cmdrhub.com. Access multiple sites and
Commanders from a single dashboard, My Hub.
Visual alerts direct you to any areas requiring attention, email notifications enable easier real-time
maintenance that can become more pro-active.
All Commander’s Essential Values are recorded, you can view and change the latest values or examine
historical data over many years.

Alarm events from Alarm History are recorded and retained. Examine historical event counts, or drill-
down to view individual events.

Commander’s data access can be shared with chosen registered users, and each can be assigned a
security role.

Commander Manual 32
 Telnet
Sometimes it is necessary to talk to Commander without using web pages or engineering software.
Commander has a Telnet server that you can enable and can provide simple text-based access to any
object values within Commander.
Commander supports two services within the Telnet session – query-response and IP-configuration.

Establishing a Session
Establish a Telnet session to Commander by opening a TCP/IP connection on port 23.
Messages are formatted as a line of ASCII text. Each line of text, or message, must end with a carriage-
return (control code 0x0D) and line-feed (control code 0x0A) – represented in this manual using the
symbol: ↵.
By default, Telnet is disabled, but you can enable Telnet, and configure a user-name, to act as a simple
password.
Once connected to Commander, enter the user-name and then the service:
Telnet – North Telnet
User:*****↵
Service:

For a list of services available, enter ‘?’ at the service prompt.

To close a session, send a line-feed at the service prompt. Alternatively, the session will automatically
close after 5 minutes of inactivity.

IP Configuration Service
The Telnet IP-configuration service is used to discover the current network settings of Commander.
At the service prompt, enter ‘ipc’ and Commander will respond with the current IP configuration:

Service:ipc↵
IP Configuration..
Network 1:
Address. . 192.168.192.167
Mask . . . 255.255.255.0
Gateway. . 0.0.0.0

Query Response Service

Using the Telnet query-response service, you can request and adjust the value of any object within, or
connected to, Commander.
At the service prompt, enter ‘qr’ and the Telnet session will enter query-response mode:

Service:qr↵
Q:

Enter the query command at the Q: prompt and Commander will respond at the R: prompt.

Commander Manual 33
 Reading a Value
At the query prompt, enter the object reference to read. Commander responds with the object value.
Q:object↵
R:value

For example, to read the local date & time (object O.T):
Q:O.T↵
R:01/12/15|15:40:08
Q:

Writing a Value
At the query prompt, enter the object reference and value to set. Commander will respond with ‘Ok’ to
indicate the object adjusted successfully.

Q:object=value↵
R:Ok

For example, to set the Commander label (object O.L) to ‘New Commander’:

Q:O.PL=New Commander↵
R:Ok
Q:

Error Response
If the service encounters an error when processing a query command, it will respond with the error
prompt (E:) followed by one of the following three-character error code:
Error Code Reason
OBJ Object reference invalid
ACT Action invalid – cannot read/write this object
VAL Value invalid
FLT General fault
DDV Device delivery fault
PDV Point delivery fault
NDV Network delivery fault
??? Unknown error

For example, attempt to read the invalid object reference ABCDE:

Q:ABCDE↵
E:OBJ
Q:

DEFAULTIP Switch
When DEFAULTIP switch is set ON, Commander automatically enables Telnet with a user-name
‘PROGRAM’.

Other APIs

 Updating Commander’s Firmware
When supplied, the Commander hardware contains the main system firmware released at the time of
production, along with several popular North interface drivers. For a list of these factory installed drivers,
see Appendix B.
North provide other less-used drivers, but you need to install these drivers before you can use them.
North also provide updated drivers and firmware, and you may need to install these.
You can set Commander to update its firmware from North’s cloud-based services, or install from a PC
using the Trivial File Transfer Protocol (TFTP).
Before updating Commander’s firmware, the Commander must be in Program mode – ie its PROGRAM
switch must be set to ON. We also recommend taking a complete backup of the Commander’s
configuration before updating.

Cloud Update
If Commander has Internet access, it can be instructed to check and update its firmware to the latest
released version available from North’s cloud-based servers.
Two different update options are available: the quickest is ‘in use only’, and this updates the system
firmware and drivers currently in use; the ‘factory’ option updates all the factory-installed software.
To add a driver that has not been previously installed, add the driver name to an available Interface
before updating the ‘in use’ firmware.

Updating Commander’s firmware

 To update Commander using North’s cloud-based services, follow these steps:
 Power Commander OFF, and change the internal switch PROGRAM to ON
 Re-power Commander and it will start working in Program mode – the MODE LED will flash
 Start Engineering your North device using ObSys
 Navigate to Configuration, Platform Information, Software Cloud Update
 Set Check and Update Software to ‘In-use only’ or ‘All factory installed’. DO NOT REMOVE THE
POWER during this operation.
 Check Progress for the current update activity – once completed, it will indicate the number of files
checked. Commander will restart several times during the update process
 Once update has completed, power Commander OFF and change the internal PROGRAM switch to OFF
 Re-power Commander, and it will start working in RUN mode.

TFTP Update
TFTP updating allows more control over the updating process and can be performed even when an
Internet connection is not available.

What is TFTP?
TFTP is one of the standard IP protocols. TFTP requires a client (your PC) and a server (Commander).
Before you can use the TFTP client, you will first need to turn the Windows feature on.
 To enable TFTP client on Windows, follow these steps:
 Using Start Engineering, navigate to Configuration, Interfaces
 From the Extras menu, select Enable TFTP.

Commander Manual 35
 The TFTP client is a Windows command line utility, with the following format:
TFTP –i <serverIPaddr> put "<filename>"

where <serverIPaddr> is the actual IP address of the Commander, and <filename> is the file name to
transfer.

Driver CDM Files

North distributes drivers for Commander in CDM files – these files are made to work in certain areas of
Commander’s memory – called banks. You can only load one CDM file per bank, so you must choose
which CDM to load in each bank.
ObSys setup installs CDM files within the CDMs folder of the ObSys Program Files folder – for example
“C:\Program Files (x86)\North Building Technologies\ObSys\CDMs”.

Installing or Updating a CDM

Commander only opens its TFTP server port when PROGRAM switch is set ON. This means that without
this switch enabled, Commander cannot be modified accidentally or maliciously.
 To load a CDM to Commander using your TFTP client, follow these steps:
 Power Commander OFF, and change the internal switch PROGRAM to ON
 Re-power Commander and it will start working in Program mode – it will enable its TFTP server – the
MODE LED will flash, to show Commander is in Program mode
 On your PC, run the Command Prompt
 At the command prompt, type the following to change to the CDMs folder:
CD "\Program Files (x86)\North Building Technologies\ObSys\CDMs"

 Type the TFTP command to send the file, for example:

TFTP –i 192.168.192.167 put "Bank15 Eltek v11 171101.cdm"

 Once Commander has received and checked the file, Commander will write the CDM to flash memory
(showing its FLASHWRITE LED), and when complete, will restart, and the MODE LED will flash to show
it is in Program mode again
 Close your Command Prompt window
 Power Commander OFF, and change the internal PROGRAM switch to OFF
 Re-power Commander, and it will start working in RUN mode – it will disable its TFTP server

To make this easier, the CDMs folder contains a batch file called ‘Update Commander at default IP’.
Simply paste a CDM file on to this batch file and it will TFTP send the CDM to the default IP address.

Updating Commander main system firmware

If you need to update the main Commander firmware itself, update three files: ‘Bank1.cdm’,
‘CmdrBase.bin’, and ‘CmdrExt.bin’.
You load these files individually using TFTP in the same way as the CDM files.

 Object Specifications
Once Commander has started, several objects become available within the top-level object of the device.
These objects may contain sub-objects (and each of these may contain sub-objects, and so on) – the
whole object structure being a multi-layer hierarchy. It is possible to navigate around the objects using
the ObSys Engineering Software.
Each object is specified below, along with its sub-objects.

Example Object Reference

An example of a reference to an object within Commander: the Configuration object (O) contains
Platform Information (PI), which contains Commander Version (PV) – therefore the complete object
reference is ‘O.PI.PV’.
An example of a reference to an object in a different device: the IP network object (IP) contains Default
Commander object (CDIP), which contains the object above (O.PI.PV) – therefore the complete object
reference is ‘IP.CDIP.O.PI.PV’.

The Essential Data Page object contains the configuration for a page within Commander’s database of
values. Each page has a label, access security, remote object prefix, and up to 64 objects.
The Remote Object Prefix (RP), if set, applies a root object to all remote objects within the page. It allows
the page to deal with a particular container object, for example an energy meter or fan coil, without the
need to enter the full object reference. A benefit of this is that the same page can be copied and used like
a template for similar devices. Then by only changing the Remote Object Prefix the same information
from an energy meter or fan coil at a different address can be accessed.
When the Remote Object Prefix (RP) is set, then Essential Data uses this to optimize communications in a
fault condition. When Object 1 (O1) is in a communications fault alarm state, then only this object on the
page performs the remote action – the other objects on the page will automatically fail. Once this first
object is communicating again, then normal operation will resume.

 Appendix C – Internal Switch Features
PROGRAM switch
When the internal switch labelled PROGRAM is set ON, and Commander re-powered, the Commander
enters ‘Program’ mode, where the following happens:
Flash memory programming is enabled.
Saving the Commander’s current configuration as the Default Configuration in flash memory.
Upgrading Interface Licences is enabled, as licences are held in flash memory.
TFTP service is enabled, if permitted via object, allowing new/updated CDMs and base code to be
downloaded into flash memory.
If the Web server is enabled and within five minutes after power-up, then changing network settings
and Commander Hub link are enabled.

DEFAULTIP switch
When the internal switch labelled DEFAULTIP is set ON, Commander automatically restarts and enters
‘Default-IP’ mode, where the following happens:
Commander operates with a static IP address of 192.168.192.167, and network mask of 255.255.255.0
The North IP Devices service disables checking of the Local Encryption Key. This enables an engineer
to access the Commander without knowledge of this security setting.
TELNET service is enabled, with the user ‘PROGRAM’, allows access to both ‘qr’ service and ‘ipc’
service.
DHCP Server is enabled.
Web server is enabled, and no sign-in is required (regardless of security), allowing access to all
webpages, and adjustment of any adjustable values.
Changing network settings and Commander Hub link via the Web server is enabled.

Note. The features enabled by PROGRAM and DEFAULTIP switches were changed to the above with
Commander firmware dated 01/10/21.
