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
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
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).
