RS-232 and IR Over XTP Communication
The RS-232 and IR Over XTP connector is for pass-through transmission of serial signals,
such as projector control signals, and infrared data. To pass bidirectional serial command
signals between XTP-compatible devices, connect a control device to the three leftmost
poles (Tx, Rx, and G) of the 5-pole captive screw connector. To transmit and receive IR
signals, connect a control device to the three rightmost poles (G, Tx, and Rx). The ground
(G) pole is shared.
NOTE:
RS-232 and IR data can be transmitted or received simultaneously
(see figure 18 below for wiring considerations).

Wiring the RS-232 and IR Over XTP Connector
ATTENTION:
The length of exposed wires is critical. The ideal length is
3/16 inch (5 mm).
•
Longer bare wires can short together
•
Shorter wires are not as secure in the connectors and could be pulled out.
