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 poles
(Tx, Rx, and G) under “RS-232” of the 5-pole captive screw connector. To transmit and
receive IR signals, connect a control device to the three poles (G, Tx, and Rx) under “IR.”
The ground (G) pole is shared.
NOTE: RS-232 and IR data can be transmitted or received simultaneously (see figure 8
below for wiring considerations).

ATTENTION:
• The length of the exposed wires in the stripping process is important.
• La longueur des câbles exposés est importante lorsque l’on entreprend de les
dénuder.
• The ideal length is 3/16 inch (5 mm).
• La longueur idéale est de 5 mm (3/16 inches).
• Any longer and the exposed wires may touch, causing a short circuit between
them.
• S’ils sont un peu plus longs, les câbles exposés pourraient se toucher et provoquer
un court circuit.
• Any shorter and the wires can be easily pulled out even if tightly fastened by the
captive screws.
•
S’ils sont un peu plus courts, ils pourraient sortir, même s’ils sont attachés par les
vis captives.
