iLIGHT SI-2-D System Integrator
Mounting & Installation
- SI-2-D must be mounted in a suitable enclosure to provide regulatory protection from electric shock hazard as well as protecting the iCANnet data network from tampering that could lead to reduced network security. Ensure selected enclosure provides adequate cooling ventilation.
Fixing to DIN rail
- Fix top clips over DIN rail.
- Pull down bottom clip using screwdriver.
- Close module towards DIN rail.
- Push up bottom clip to fix securely to DIN rail.
Removing from DIN rail
- Pull down bottom clip with screwdriver.
- Lift module away from DIN rail.

IMPORTANT NOTE:
Connecting a mains potential cable to the iCAN Network terminals is likley to
damage the unit and other devices connected, and invalidate warranty.
Serial device connection
The SI-2-D provides an RS232 link via a standard 9-pin D-type female
connector. The SI-2-D uses five pins of the D-type connector as shown below:
Network
termination
The iCAN network follows a daisy chain topology that requires termination on
the devices located at either end of the network.
The SI-2-D unit
is supplied with termination disabled as standard. If it is connected as an
end device in the iCAN network, you need to move the jumper to enable
termination.
The connection of the serial data cable to the device is treated separately
and has no impact on whether or not the SI-2-D should be terminated on the
iCAN network side.
To enable SI-2-D termination, move the jumper out-wards from the inner two
pins to the outer two pins:
