Wiring the Contact Input Port

The IPL T PC1 contact closure Input port can be connected to any device providing a closure to ground (closed = logic 1 and open = logic 0). The contact input is connected to 5 VDC via a 1k ohm pull-up resistor and must be wired with a ground. This allows the input to be tied to a device such as a motion detector, alarm, photo eye, and so forth. You can define what this input will trigger via GC3.3.

1.Connect one end of the input cable to a 3.5 mm, 2-pole captive screw connector (provided), and plug the connector into the two Input pins (In and _ ) of the shared Input/IR port connector on the rear panel.

Alternatively, you can wire the contact closure device to pins 1 and 2 (from the left) of the provided 4-pole captive screw plug (and, if desired, also wire an IR emitter to pins 3 and 4 of the same 4-pole connector; see “Wiring for IR Control” on the previous page). Plug the wired 4-pole connector into the rear panel Input/IR connector.

2.Connect the other end of the input cable to the contact input device that will provide a triggering signal (see the diagram at right).
