The units can be purchased as a pair (of the same form factor) 
or individually. Each purchased pair and each individual 
transmitter is shipped with a single external desktop 12 VDC 
power supply that accepts 100 to 240 VAC, 50 Hz or 60 Hz input.  
A single power supply connected to either the transmitter or the 
receiver can power both units through one of the TP cables that 
link the units.

About the HDMI 201 Tx/Rx
The Extron HDMI 201 Tx/Rx is a family of HDMI transmitters 
and receivers, in enclosures that support different mounting 
options. A transmitter and receiver pair extends the usable 
distance of DVI or HDMI digital video and RS-232 control 
signals over two Category (CAT) 5/5e/6/7 unshielded 
twisted pair (UTP) or shielded twisted pair (STP) cables. The 
HDMI 201 A D transmitter and receiver also route audio. The 
video and control (and audio, if applicable) signals can be 
transmitted up to 200' (60 m).

Figure 1-1 — Typical transmitter and receiver application
An HDMI 201 system consists of a transmitter (Tx) and a 
receiver (Rx). The pair can handle HDMI digital video and a 
bi-directional RS-232 link. The HDMI 201 A D also converts a 
computer audio input into balanced or unbalanced stereo audio 
output.
