Network Connections
Network Cable Topology
The iLight Network is of CAN bus (Controller Area Network) standard. A maximum of 100 devices can
be added to the network on a single run. NOTE: Device quantity can be increased with a BN-2-D Network
Bridge/Repeater unit.
The network must be wired in a ‘daisy-chain’ radial configuration, resulting in two end-of-line positions for
the CAN pair. The order that devices are situated on the network is not specific, but power must be evenly
distributed across the network for powering Control Plates, Interfaces and other input devices. Additonal
power supplies may be required.

Three-phase Operation
SCA1210 maintains output terminal order
according to channel number, rather than
grouping the outputs together by phase.
For SCA1210, the output LEDs to the right-
hand side of the unit are grouped by phase.
This is because each of the three Power
PCBs are controlling each of the phases.
Therefore, if the second LED down on the
right side of the unit is on, and the circuit
needs to be isolated, this corresponds to
the second output of phase L1, which is
output channel 4 and therefore breaker
number 4 on the Source Controller.
