Rear Panel Decora and Box Configuration Summary
A use of the GP68 breakout box is to increase the command and capacity of CT products, allowing for multiple
control systems for one zone. Shown below is an IR receiver and keypad connected to control the same zone, in
this case Zone D. In this instance, the IR receiver would use the pin configuration of the IR input on the CT
receiver, in this case using pin 2 for DATA and pin 3 for ground. The keypad uses pin 1 for +12V power, pin 2
for DATA, pin 3 for ground, pin 5for RS-232 status and pin 7 for 12V CTRL (control light on keypad).
