TP cable termination
N RJ-45 termination with CAT 5, CAT 5e, or
CAT 6 cable must comply with the TIA/EIA T 568A or
TIA/EIA T 568B wiring standard for all connections.
Figure 2-20 details the recommended termination of TP cables
with RJ-45 connectors in accordance with either the
TIA/EIA T 568A or the TIA/EIA T 586B wiring standard.

Figure 2-20 — TP cable termination
N Do not use Extron’s UTP23SF-4 Enhanced Skew-Free ™
A/V UTP cable to link the transmitter and receiver.
Skew-free A/V cable was designed for most Extron
TP transmitter/receiver applications, but the
HDMI 201 Tx/Rx does not work properly with this
cable.
N In order to fit in the junction box, the TP cables and
RJ-45 connectors should not have a boot installed.
N If necessary, test for proper cable connection (output 1 to
input 1, output 2 to input 2) as follows:
1. Plug both TP cables into the powered unit.
2. Momentarily connect either of the cables on the
opposite end into the unpowered unit‘s “2” connector.
If the unpowered unit’s Power LED is lit, the
connection is correct.
If the unpowered unit’s Power LED is not lit,
unplug the connector on the unpowered end and
connect the other cable to the “2” connector.
