5. Button Control

5.1 Manual Switching

When the switcher is in the manual switching mode, press the SELECT AUTO/3s button repeatedly to cycle through the two video inputs, and the corresponding source LED illuminates orange immediately.

5.2 Automatic Switching

Press and hold the SELECT AUTO/3s button at least three seconds to enable automatic switching. The current input source will not be changed, and its source LED will turn green.

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

• Press and hold the SELECT AUTO/3s button at least three seconds again can exit AUTO mode, but the input source will not be changed, and the corresponding source LED will turn orange.
• New input: Upon detecting a new input, the switcher will automatically select the new input.
• Press the SELECT AUTO/3s button also can forcibly change the input source.
• Reboot: Once 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 other active input.

5.3 Display Control

Manual Control: Press the below DISPLAY buttons on the front panel to simultaneously send RS232 and CEC commands to control the display device.

• ON: Display On.
• OFF: Display Off.
•UTE/unmute display audio.
• Volume down display audio.
Volume up display audio

signal within the setting time (default 10mins), automatically send RS232 and CEC commands to turn off the display device.

The RS232 command can be set by sending commands, please refer to the 6.2.7 Third-party Device Control for more details.

5.4 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 source device obtains its EDID from the first connected display. Meanwhile, since the displays with different capabilities are connected to the switcher, the 4-pin DIP switch on the front 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.
