Manual Switching

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

Automatic Switching

Press and hold the SELECT button for at least three seconds to enable automatic switching.
When in the AUTO mode, the unit will switch according to the following rules:

• New host: Once detecting a new host, the unit will automatically select the new host.
• Pressing the SELECT button will forcibly change the host even in AUTO mode.
• After reboot: Once power is restored to the unit, it will automatically reconnect the host that was active before the reboot.
• Source removed: When an active host is removed, the switcher will switch to the other active host.
• Press and hold the SELECT button for at least three seconds and the unit will exit AUTO mode and the host will not change.

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.
: Mute/Unmute display audio.

EDID Settings

The switch represents “0” when in the lower (OFF) position, and it represents “1” in the upper (ON) position.

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, pins1~3 of the DIP switch on the front panel can be used to set the EDID to a built-in fixed value.

HDCP Settings

High-bandwidth Digital Content Protection (HDCP) is a copy-protection scheme to eliminate the possibility of capturing digital content from the source to the display. Pin4 of the DIP switch on the front panel can be used to set HDCP.

USB Host Power

The total USB host power supply is 100W and there are 3 modes can be set via RS232 commands, as defined below:

RS232 Control

Connect an RS232 cable to a control device (e.g. PC) with an RS232 cable. The switcher can then be controlled by sending RS232 commands. The baud rate is selectable as follows: 2400, 4800, 9600(default), 19200, 38400, 57600 or 115200.
