Repeatedly press the OUTPUT button on front panel to cycle through the various
inputs for the corresponding output.
Press and hold PRESET RECALL button 1~3 to save the current switching status to
the corresponding preset 1~3.
Press the PRESET RECALL button 1~3 to recall the saved preset 1~3.
5.2 EDID Setting
The Extended Display Identification Data (EDID) is used for the source device to
match its video resolution with the connected display. By default, the EDID of source
device is 1080P PCM 2CH. Meanwhile, since the displays with different capabilities
are connected to the matrix, the 4-pin DIP switch on the rear panel can be used to set
the EDID to a built-in fixed value. Use the following table to determine the setting for
the 4-pin DIP switch for specific video resolution and audio capabilities. The switch
represents “0” when in the lower (Off) position, and it represents “1” while putting the
switch in the upper (On) position.
Note:
2CH: LPCM 2Ch.
Multi-CH: 8Ch LPCM, Dolby TrueHD, DTS-HD, Dolby Digital5.1, DTS 5.1, Dolby
Digital Plus.

6.2 IR Pass-through Control
6.2.1 Control Far-end Device locally
Connect an IR receiver to IR IN port of the matrix; users can control far-end display via
its IR remote from local.
In that case, the IR signal is transferred via twisted pair. Only the corresponding IR
OUT port can emit control signals to the remote display.
See the figure below:
6.2.2 Control Local Device Remotely
Connect IR receiver(s) to IR IN ports on far-end HDBT receiver(s), and IR emitter(s) to
IR OUT ports of the matrix, and use the IR remote of local source to control the device
remotely.
One to One:
Connect an IR receiver to IR IN port on far-end HDBaseT receiver, and an IR
emitter to IR OUT 1 port of the matrix. Use the IR remote of local source to control
the device remotely. See below:
