NOTE: When using STP cable in bundles or conduits, consider the following:
•
Do not exceed 40% fill capacity in conduits.
•
Do not comb the cable for the first 20 meters, where cables are straightened, aligned,
and secured in tight bundles.
•
Loosely place cables and limit the use of tie wraps or hook-and-loop fasteners.
•
Separate twisted pair cables from AC power cables.
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 11 for wiring considerations).

ATTENTION:
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).
•
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.
