Installation Instructions
Installation Instructions
1. Using quality HDMI cables, connect an HDMI source (such as
Blu-ray, games console, satellite/cable TV, media server etc.) to
HDMI IN of the Transmitter.
2. Connect a good quality Cat5e cable between the HDBT OUT of
the Transmitter to the HDBT In of the Receiver.
3. Connect the HDMI display device (LED/LCD display or projector)
to the HDMI Out of the Receiver.
4. For two-way IR control of connected sources and displays from
either location, first, connect IR emitters to the IR Out ports of the
Transmitter and Receiver, and then insert IR receivers into the IR
In ports of the Transmitter and Receiver.
5. Connect the included 12V power supply to the Transmitter and
power on. The PoH function carries power along the length of
the cable one-way to power the Receiver. No additional power
supply is required at the display end of the cable run.
Make sure Power, Status, and HDCP & Link lights are illuminated on
both units to indicate successful connection, with a lit HDCP light
illustrating the presence of encryption within the signal. Power and
Link are static lights. Status should be blinking.
