HARDWARE INSTALLATION
AV-GM0823-S1 as master
1. Connect all sources to HDMI Inputs on the 8x8 HDMI over CAT.X matrix master AV-GM0823-S1.
2. Connect each CAT.X output port on the AV-GM0823-S1 TX to respective CAT.X input on the
remote receiver AV-GM0823-S1 RX.
3. Connect IR blaster to the AV-GM0823-S1 TX and direct the IR blaster to point towards the built-in
IR receiver of the HDMI source devices.
4. Connect the +12V 5A DC power supply to the AV-GM0823-S1.
5. Power on all HDMI sources.
AV-GM0823-S1 RX as receiver
1. Connect each HDMI output to HDMI displays.
2. Connect the CAT.X input on the AV-GM0823-S1 RX to the CAT.X output port on the AV-GM0823-S1
TX.
3. Connect IR receiver and place the IR receiver at the appropriate position that can receive the IR
signals sent from the users.
4. Dial the 8-level rotary control switch to adjust the HDMI signal level until the picture and sound
are clear. It is recommended to dial from weakest to strongest to find the optimal visual
experience
You can buy any IR extension cables in the market that are compatible to the definition of
the IR sockets for the matrix if necessary for replacement use. However, IR cables longer
than 2m (6-ft) may not work.
