RS-232 connector — Connect a serial communications port to
this 3.5 mm, 3-pole captive screw connector for bidirectional
RS-232 communication. See "RS-232 connector wiring," on
page 2-26, to wire the connector.
N The RS-232 connector can also transmit one-way
modulated infrared (IR) signals. See "Modulated IR
pass through" on page 2-33.
m
Audio output connector (DVI 201 A D Tx [Decora] only) —
Connect a stereo audio device to this 3.5 mm mini stereo jack to
receive the unbalanced audio output. Figure 2-14 on page 2-17
shows how to wire the audio plug.

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 568B 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
DVI 201 Tx/Rx will 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.
