Firstech, LLC CM3 SERIES, CM1000A, CM4200 Channel Expander, Connector 1 Input, Connector 2 Output

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.
