GMCT20 Cable Installation Instructions
GMCT20-BARE WIRE Cable
The GMCT20-BARE WIRE cable is recommended for connecting the switch module to your system
if termination other than a GMCT20 connector is required. One end of the cable terminates with a
GMCT20 connector. The other end of the cable has twenty unterminated, tinned, and stripped wires.
Use the pinouts and the pin assignments listed in Table 2 to determine how to connect signals to your
application.
In the following table, letters in parentheses reference the pin designators of the connector.
