Multi-View Selection

• By default, the switcher is set to quad-view, and the input-output correspondence is: Input 1-Window
• A, Input 2-Window B, Input 3-Window C, Input 4, Window D. To change the multi-view mode, press one of the other two multi-view buttons. The LEDs of the selected multi-view layout and corresponding windows will light up blue.
• To switch to full-screen, press one of the Windows A~D buttons to display the corresponding window full-screen. While in Fullscreen mode, the LEDs of the selected input source and window will light up blue, and the LEDs of all other window and multi-view mode buttons will turn off.

Video Signal Switching In Multi-View Mode

• Operation: Input # + Window #
• Example: Switch Input 1 to Window B
• Press Input 1 (the Input 1 LED will turn blue, and the Windows A~D LEDs will flash), then press Window B (the Windows A, C, and D LEDs will go out, then the Input 1 and Window B LEDs will flash 3 times, and then the Input 1 LED will go out and the Windows A~D LEDs will turn blue).

In Full-Screen Mode Manual Switching

• Operation: Input # + Window #
• Example: Switch Input 2 to Window A
• Press Input 2 (the Input 2 LED will turn blue), then press Window A (the Input 2 and Window A LEDs will turn blue).

Auto-Switching

Press the AUTO button to enter Auto-Switching mode (the AUTO LED will turn blue). When in Auto-Switching mode, the signal switching obeys the following principles:

1. HDMI Input Priority: HDMI 1 > HDMI 2 > HDMI 3 > HDMI 4; when an input source and output window are connected, the corresponding LEDs will turn blue
2. New Signal: When the switcher detects a new input signal, the switcher will switch to the new signal automatically
3. Last-Selected Input: The switcher will remember which input source was last selected when it is powered off, and will automatically switch to that source when powering back on
4. Manual Switching: It is possible to switch sources manually while the switcher is in Auto- Switching mode, and doing so does not exit Auto-Switching mode
5. Multi-View: Changing from Fullscreen to Multi-View mode will not exit Auto-Switching mode.

Video Switching Status Inquiry

• In Multi-View mode (Window A, B, C, or D LEDs lit up blue)
• Operation: Window #
• Example. Press and hold the Window B button for at least 3 seconds. The Window A, C, and D LEDs will turn off, and the LED of the input source currently assigned to Window B will turn blue. After 3 seconds, the input source LED will turn off, and the Window A, C, and D LEDs will turn back on.

Audio Selection

• By default, the audio source is set to HDMI 1. In Multi-View mode, pressing and holding any of the
• Input 1~4 buttons for more than 3 seconds will change the audio output to the corresponding input source, and the input’s LED will turn blue. After 3 seconds, the input LED will turn off.

Firmware Upgrade

1. Prepare the upgrade file (.bin) on the PC, and rename it as “FW_MV.bin”
2. Power off the switcher and connect the FIRMWARE port of the switcher to the PC with a Type- A USB cable
3. Power on the switcher, and the PC will automatically detect a flash drive named “BOOTDISK”
4. Copy the upgrade file (.bin) onto the “BOOTDISK” flash drive
5. Close the flash drive, and wait for the switcher’s firmware to update
6. Reopen the flash drive and check for a file named “SUCCESS.txt”. If this file is present, the firmware has been updated successfully. If the file is missing, then the firmware update has failed. Double-check the named of the upgrade file, the repeat the previous steps.
7. Remove the USB cable after the firmware upgrade is complete
8. Perform a factory reset on the switcher by sending the appropriate command (see §8.1 System Control)
