ARC Connection:

5. Button Control

5.1 Manual Switching

When the switcher is in manual switching mode, the AUTO button LED goes out. Please follow the below steps to switch input source to output channel.

1) Press Select button at Out A block to select input source for output A, and the corresponding source LED turns green.
2) Press Select button at Out B block to select input source for output B, and the corresponding source LED turns green.

5.2 Auto Switching

Press and hold Select button at least 3 seconds at Out A block to enable auto switching mode for output A, and then the Auto LED will turns green.

Press and hold Select button at least 3 seconds at Out B block to enable auto switching mode for output B, and then the Auto LED will turns green.

When in auto switching mode, the switcher will switch according to the following rules:

• The switcher will switch to the first available active input starting at input 1 to 4.
• New input: The switcher will automatically select the new input once detecting a new input.
• Reboot: If power is restored to the switcher, it will automatically reconnect the input before powered off.
• Source removed: When an active source is removed, the switcher will switch to the first available active input starting at HDMI input 1.
• Detection method: TMDS or 5V (The default is 5V and it can be selected by RS232 commands).
• Press the Select button can switch to next input source, and the switcher doesn't exit the auto switching mode.

Note: In auto switching mode, press and hold the Select button at least 3 seconds to enable manual switching mode, but the input source will not be switched.

5.3 EDID Setting

The Extended Display Identification Data (EDID) is used by the source device to match its video resolution with the connected display. The 4-pin DIP switch on the front panel can be used to set the EDID to a fixed value to ensure the compatibility in the video resolution.

The switch represents "0" when in the lower (OFF) position, and it represents "1" while putting the switch in the upper (ON) position.

Switch 1\~3 are used for built-in EDID setting, and switch 4 is used for mode setting.

The DIP switch status and its corresponding setting are shown as below chart.

Switch 1~3 Status	Video Resolution	Audio Format
000	Pass-through	Pass-through
001	1920x1080@60Hz 8bit	Stereo
010	3840x2160@30Hz 8bit	Stereo
011	3840x2160@30Hz 8bit HDR	Stereo
100	3840x2160@30Hz Deep Color HDR	PCM 5.1
101	3840x2160@60Hz 8bit	Stereo
110	3840x2160@60Hz Deep Color HDR	PCM 5.1
111	User-defined EDID
Switch 4 Status	Mode
0	Global Mode.
1	Out B Private Mode.

EDID setting rules:

When switching one input to output A and output B, the switcher is used as a 1x2 splitter, the input source device obtains its EDID from the output display with priority output B>output A. If video switching fails in EDID pass-through mode, set the built-in EDID to 1080p.

1) When the specifications of output A and output B display devices are same, set the EDID to Global Mode. When switch same input to output A and output B, because the supported resolution (4K@60Hz 4:4:4) of two outputs are same, the input source device will not reread the EDID of display device to ensure non-flash screen.

2) When the specifications of output A and output B display devices are different, set the EDID to Out B Private Mode, and the Out A is in Pass-through mode.

√ When switching the input source of output A to output B, because the input source device will first learn the EDID from output B, so the two output displays will flash before the image appears.

√ When switching the input source of output B to the output A, because the input source device will first learn the EDID from output B, so the display device of output B doesn't flash, but the display device of output A will flash before the image appears.

6. IR Remote Control

Connect IR receiver to the IR EYE port, the switcher can be controlled by the following IR remote.

① 1-4: Press 1-4 button to select corresponding input source for OUT A.

AUTO: Press the button to enable auto switching mode for OUT A.

② 1-4: Press 1-4 button to select corresponding input source for OUT B.

AUTO: Press the button to enable auto switching mode for OUT B.

③ De-embedded: Press A or B button to select output A or output B de-embedded audio for audio output.

ARC: Press A or B button to select output A or output B ARC audio for audio output.

9. Firmware Upgrade

Please follow the steps below to upgrade the firmware by the FW port on the front panel:

1) Prepare the latest upgrade file (.bin) and rename it as "FW_MERG.bin".
2) Connect the switcher to the PC with USB to Micro USB cable, and then power on the switcher. The PC will automatically detect a U-disk named of "BOOTDISK".
3) Double-click the U-disk, a file named of "READY.TXT" would be showed.
4) Directly copy the latest upgrade file (.bin) to the "BOOTDISK" U-disk.
5) Reopen the U-disk to check the filename "READY.TXT" whether automatically becomes "SUCCESS.TXT", if yes, the firmware was updated successfully, otherwise, the firmware updating is fail, the name of upgrade file (.bin) should be confirm again, and then follow the above steps to update again.
6) Remove the USB to Micro USB cable after firmware upgrade, and reboot the switcher.
