Button Control

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 LEDilluminates red immediately.

Automatic Switching

Press and hold the SELECT AUTO/3s button for at least three seconds to enable automatic switching. The current input source will not be changed, and its source LED will turn blue. When in the AUTO mode, the switcher will switch according to the following rules: Press and hold the SELECT AUTO/3s button for at least three seconds again can exit AUTOmode, but the input source will not be changed, and the corresponding source LED will turned.

EDID and HDCP Setting

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

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, pins 1~3 of the DIP switch on the front panel can be used to set theEDID to a built-in fixed value.

HDCP Setting

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.
