RS-232 and IR Over XTP Communication
The RS-232 and IR Over XTP connector passes 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 9 below for wiring considerations).

Figure 9. Wiring the RS-232 and IR Over XTP Connector
ATTENTION: The length of the exposed wires in the stripping process is critical.
ATTENTION :
La longueur des câbles exposés est primordiale 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).
• If the exposed portion is longer, the 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.
•
If the exposed wires are shorter, they 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.
• Do not tin the wires. Tinned wire does not hold its shape and can become loose
over time.
• Ne pas étamer les câbles. Les câbles étamés ne sont pas aussi bien fixés dans les
terminaisons des connecteurs à vis captives et pourraient sortir.
