Installation
Verify that the distance between the HDMI Transmitter and Receiver are within MuxLab
specifications (see Specifications table).
If the receiver is being used without a PSU then the switch
must be set to "No-Power" and if the receiver is being used
with PSU, then the switch must be set to "Power" (factory
setting)
Identify the pin configuration of the baluns. Two (2) Cat5e or better are required. The pin
configuration follows the EIA/TIA 568A/B standard. The HDMI Wall Plate Extender Kit is
reverse polarity sensitive. Please ensure that wiring is straight through (Ring to Ring, Tip to
Tip).
1.
To install the HDMI Transmitter or Receiver in a single
back box, choose a back box with a depth of 40 mm or more
or a mud ring. Connect the RJ45 plug into the rear of the
extender. Secure the extender with the 2 front screws.
In order to install the Transmitter, please follow the steps below:
2.
Connect the Transmitter to the HDMI video source with an HDMI compliant cable.
3.
Connect two (2) lengths of Cat5e (or higher) grade UTP cables to the Video and DDC
OUT connectors on Transmitter.
In order to install the Receiver, please follow the steps below:
4.
Connect the Receiver to the HDMI display equipment with an HDMI compliant cable.
5.
Connect the two (2) Cat5e cables to the Video and DDC IN connectors of the Receiver.
Note: Verify that the cables are connected straight-through (i.e. Video to
Video, DDC to DDC) and not inverted.
6.
Connect the 12 VDC power supply first to the Receiver and then plug the power supply
into an AC power outlet. If power is present, then the green power LED will be ON.
Note: Power the HDMI Wall Plate Extender Balun only after all connections are
made.
7.
Power on the HDMI equipment and verify the image quality.
