Connecting two wire addressable Bus
The two wire addressable bus is used for user interface
devices and individually addressable smart LED drivers.
Each two wire module (SCMD4) will be pre-mounted on the
interior DIN rail per the order specifications and provide four
(4) two wire addressable buses. Each two wire addressable
bus supports up to 64 addresses per bus.
Use 14AWG cable for the two wire addressable bus and do
not exceed 300 meters (984ft). The two wire addressable
bus is polarity and topology free.
The two wire addressable bus provides 250mA per bus to
power addressable devices. The following table provides
information on devices that can connected to the two wire
addressable bus

Follow these rules when connecting the two wire
addressable bus:
• Torque = 0.4N-M (XXX in-lbs)
• Wire Sizes: 18-12AWG solid/stranded copper only
• Load to: 200mA maximum draw
• Acceptable for Class 1 or Class 2 wiring per NFPA 70
section 725.XX and CEC 16.1000 if wiring methods per
16.114 are used
Connecting to the lighting network
Medium and large iLumin Plus panels include the CR1-RJ PC
connection device. A PC can be connected to the iLumin
Plus panel using the SW2 cable kit plugging into the RJ port
on the CR1-RJ. If this iLumin Plus panel is connected to the
lighting network the PC will have access to all iLumin Plus
devices on the lighting network.
In a medium or large iLumin Plus panel one side of the CR1-
RJ will not have wires connected. This terminal is used to
connect to other iLumin Plus panels. The lighting network
is a daisy-chain and requires one in and one out connection.
The lighting network also requires a terminating jumper
installed at the two ends of the network
Lighting network wire should use Eaton LCCP or LCCNP
wire. (alternate: Belden 1502, 1502P)
