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

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.

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.
