Channel Expander
The channel expander is an add-on module that can be used to expand the existing two
auxiliary outputs to a total of seven auxiliary outputs. Each one of these seven outputs
can be individually programmed for pulsed, latched, or timed-latch output. The
programming of the Channel Expander outputs must be done with the Option
Programmer; the CompuStar remotes do not have the ability to access these programming
options.

Connector 1 - Input
Pin1: This is the ground wire for the Channel Expander. Ground this wire to the vehicle
chassis.
Pin2: This is the data input wire used to communicate with the CompuStar brain module.
Connect this wire to the Aux 1 output wire from the CompuStar brain module.
Pin3: This is the 12v constant wire for the Channel Expander. Connect this wire to a
constant 12v+ source within the vehicle.
Connector 2 - Output
