Introduction
Introduction
The Network Bridge allows two iCAN networks to be
connected together. The BN-2-NA is used to extend the
network where more than 3200 ft./1000m of cabling is
required or more than 100 devices is required, as well as
filtering of network messages.

iCANnet termination
The iCANnet link is a ‘daisy chain’ protocol that requires
termination on the devices located at either end of the
iCANnet chain.
iCAN
Device
The BN-2-NA unit is supplied with termination enabled as
standard. If it is not connected as an end device in the
iCANnet chain, you need to disable termination.
To disable BN-2-NA termination, move the jumper from the
lower two pins to the upper two pins, as shown here:

iCANnet Announce Button
The BN-2-NA unit features a small button adjacent to the green connector
which can be used to add the device to an iCANnet network. When pressed,
the BN-2-NA will send an announcement message across the iCANnet
network. Please see the section ‘Adding the BN-2-NA to iCANsoft’ for more
details.

Typical Network Design
Typical Network Design
Repeater Mode
In Repeater Mode, the bridge passes all traffic in both directions. It doesn’t filter at all. This mode is used primarily to split
networks into 2 segments. Usually this will be due to long cable lengths, or if there are more than 100 devices.
Bridge Mode
When in Bridge Mode, the bridge will only pass traffic for one segment. This is to minimize traffic onto the network. This is
typically used on large networks, with 100’s or 1000’s of devices, connected across many segments.

Combination
When in Bridge Mode, the bridge will only pass traffic for one segment. This is to minimize traffic onto the network. This is
typically used on large networks, with 100’s or 1000’s of devices, connected across many segments.
Large projects may require a combination of BN-2-NA Network Bridges in bridge mode, as well as, repeater mode.
Programming - within iCANsoft
This section provides details about programming items specific to the BN-2-NA network bridge within the
iCANsoft application. For details about the general use of iCANsoft, please refer to the System manual.
Adding the BN-2-NA to iCANsoft
Once the BN-2-NA network bridge has been connected to the iCANnet network, you can add it to the iCANsoft
application in any of the following three ways:
Within the iCANsoft main window, click the icon,
Within the iCANsoft main window, select ‘Tools’ > ‘Advanced Network Search’, or
On the BN-2-NA unit, adjacent to the green connector block, press and release the small button to cause an
announcement message to be sent across the network.
ote:N Where there are multiple BN-2-NA units installed on a network, you can use the announce button to pinpoint the
device within iCANsoft. Its entry within the device list will appear in bold and the iCAN soft output section will provide
device number details.

Programming - General settings
The BN-2-NA configuration window
This tabbed window provides all of the options necessary to
program the BN-2-NA unit.
Viewing BN-2-NA details in iCANsoft
Once the BN-2-NA unit has been added to the iCANsoft
application, it will appear in the devices list within the
workspace window:
To view the configuration window for the BN-2-NA network
bridge, double click its entry within the list.
Programming - General settings
Repeater Mode
The Network Bridge is not used to filter messages, so the
device number is not important.
Bridge Mode
The Network Bridge should be programmed to use
segment 1, so the device number is 1 – xxx.
Click on Renumber to change the device number.
If the Network Bridge is device number 1 – 6, it will manage
all devices on segment 6. All devices on the local (right)
network will need to be renumbered to 6 – xxx, so that
iCANsoft can configure them from the backbone (master)
network.

Programming - General settings
Virtual Filters
Each Network Bridge can have up to 16 filters for virtual
messages. Double-click the filter to configure it:
The default is to have none of the filters configured. This
means that no virtual messages will be transmitted onto the
local network (across the bridge).
Repeater Mode
Repeater mode is used when a network is either too long
or has too many devices, and there’s no requirement for
filtering messages.
Bridge Mode
Bridge mode is used for large networks, typically when
there is a backbone network that covers several levels of a
building. It is good practice to isolate messages from one
segment being sent onto another segment.
Ranges of Virtual Areas can be added, or just a single
area. Areas can also be excluded. This allows flexibility so
that only the relevant messages are passed onto the local
network.
It’s good design practice to plan area numbers before
commissioning a project. The numbers aren’t important, but
use a range of numbers for each segment. That way you
only need to use a few filters, perhaps even one.
Example: segment 5 will use areas 500 – 599, segment 6
will use 600 – 699
Options
There are 3 modes of operation for the Network Bridge
Repeater
Bridge
Locked
Locked Mode
Locked mode is used for testing and diagnostic purposes,
and will prevent all messages from being sent across the
bridge.
Sequences
The sequence engine can be disabled. It can also be
configured to send messages just to the local network, or
across onto the backbone as well (global).

BN-2-NA Network Bridge

Sequences allow you to link a number of individual actions
together, with or without a time delay between each, in
order to cause multiple operations from a single trigger
action. The BN-2-NA can store up to sixteen sequences of
its own (each with up to 128 steps) that can be triggered by
an action via the iCANnet network.
To define a sequence
1. Click on the ‘Sequences’ tab to display the page.
2. Right click within the main panel area to display a
popup menu. Select the ‘Add’ option to add a step to
the sequence.
4. Click the ‘Action Type’ down arrow and select the
required action form the list. Depending upon the
chosen action, one or more of the ‘Param’ columns to
the right will show their own selection options. You can
use these to further define the selected action.
5. Repeat steps 2 to 4 for each required step within the
sequence. When all have been configured, either click
the Apply button to save without closing the window or
click the OK button to save and close.
3. Optionally alter the delay option (introduces a time
delay before the current action is launched).
