  DCpowerinputconnector — Plug the included external 
12 VDC power supply into either this 2-pole connector or the 
power input connector on the transmitter (item 
d
 on page 2-17).  
See "Power supply wiring," on page 2-25, to wire the connector.
h
  Receiverinputconnector— Connect one end of the two 
separate TP cables from the transmitter output connectors (item 
e
 on page 2-17) to these RJ-45 female connectors.
C
  Do not connect these devices to a computer data or 
telecommunications network.
N
  Extron recommends 28AWG to 24AWG TP cable for the 
RJ-45 connectors.
N
  Connect transmitter output 1 to receiver input 1. 
Connect transmitter output 2 to receiver input 2.
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.
See "TP cable termination," on page 2-22, to properly wire the 
RJ-45 connectors.

  HDMIOutputconnector— Connect a display with an HDMI 
input for display of the transmitted direct digital image. See 
"HDMI connector pin assignments," on the next page, for pin 
assignments.
j
 RS-232connector—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.

  AudioInputconnector(HDMI201ADRx[Decora]only)— 
Connect one end of a 5-wire audio cable to this 3.5 mm, 5-pole 
direct insertion connector.
  Connect the free end of the same cable to any compatibly 
wired audio source unit, such as a switcher's output or a 
HDMI 201 A D Tx (Decora) transmitter (item 
f
 on page 2-18).
  Figure 2-18 shows how to wire the captive screw audio 
connector. Insert the wires into the appropriate openings in the 
direct insertion connector. Tighten the screws on the side to 
fasten the wires.
