INSTALLATION
Connection Cables
1. Connect the video source device to the Local Unit (TX) at the "HDMI INPUT" port with an HDMI cable.
2. Connect a CAT6/CAT6a/CAT7 cable between 2 and 70 meters in length between the "CAT6 OUT" on the Local Unit and the
"CAT6 IN" on the Remote Unit (RX).
3. Connect a display device to the Remote Unit at the "HDMI OUTPUT" port with an HDMI cable.
4. If using HDMI Loop Out, connect a display device to the Local Unit at the "HDMI OUTPUT" port with an HDMI cable.
5. If cascading Remote Units, connect a CAT6/CAT6a/CAT7 cable between 2 and 70 meters in length between the "CAT6 OUT"
on the first Remote Unit to the "CAT6 IN" on the second Remote Unit. Repeat this step for any additional Remote Units, for up to
10 total Remote Units and a total of 700 meters of CATx cable.
6. Plug the power supplies (provided) into the Local Unit and Remote Unit.

IR Cables
1. Connect an IR Emitter into the "IR OUT" port on the Local Unit, and the other into the same port on the Remote Unit.
The emitter should be placed as close as possible to the IR receiving sensor/window on the video source.
2. Connect an IR Receiver into the "IR IN" port on the Local Unit, and the other into the same port on the Remote Unit.
The Receiver should be placed where it is convenient to receive control signals from the IR Remote.
With 10 Remote Units, you can have a total of up to 700 meters of CATx
cable between the Video source and the last HDMI Display.
