  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 
HDMI201Tx/Rxdoesnotworkproperlywiththis
cable.
N
  In order to fit in the junction box, the TP cables and 
RJ-45 connectors should not have a boot installed.
N
 Ifnecessary,testforpropercableconnection(output1to
input 1, output 2 to input 2) as follows:
1.  Plug both TP cables into the powered unit.
2. Momentarilyconnecteitherofthecablesonthe
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.
