NOTES:
•
The length of exposed wires is important. The ideal length is 3/16 inch
(5 millimeters).
•
•
•
Do not tin the power supply leads before installing them in the connector. Tinned
wires are not as secure in the connector and could be pulled out.
TP Cable Termination and Recommendations
Figure 17 details the TIA/EIA T 568 B wiring standard. Use this standard to terminate the
DTP2 cable with RJ-45 connectors.

Figure 17.
NOTE: Do not use Extron UTP23SF-4 Enhanced Skew-Free AV UTP cable or STP201
cable to link the switching transmitter and receiver. The DTP2 T 202 FB does not work
properly with these cables.
RS-232 and IR Connectors Wiring
If the stripped section of wire is longer than 3/16 inch, the exposed wires may
touch, causing a short circuit.
If the stripped section of wire is shorter than 3/16 inch, wires can be easily pulled
out even if tightly fastened by the captive screws.
