Computer3	:= 02 + 'INP:8' + 03;	// Select HDMI-2
Video1	:= 02 + 'INP:1' + 03;	// Comp Video/S=Vid (on same channel, S-Vid has priority)
Video2	:= 02 + 'INP:3' + 03; // SCART 1 video via adaptor
Video3	:= 02 + 'INP:4' + 03; // SCART 2 video via adaptor
Video4	:= 02 + 'INP:5' + 03; // SCART 2 s-video via adaptor

Video8	:= 02 + 'INP:0' + 03;	// Select TV

Any one of these codes can be set into Constant:0/Constant:1 for computer codes and Constant:2/Constant:3 for video codes. (The default is to have Computer1 (above) as the “Computer” channel and Video1 as the “Video” channel. Setting OPT1 switch ON will swap Video1 and Video2 channels.)

The TV setting uses the following command:

TV	:= 02 + 'INP:0' + 03; // Select TV

This panel can be used with a number of keyboards:

•With a “Code 9” or “Code A” keyboard, with buttons selecting “Video” and ‘Computer”, with either “Volume” (code 9) or “Freeze/Mute” (Code A);

•With a “Code B-L” or “Code B-P” keyboard, with buttons selecting “Video” and “Computer1” and “Computer2” with Volume control keys; or

•With a “Code E” keyboard, with buttons selecting “TV”, “Video” and “Computer”, with TV channel Up/Down and Volume control keys. The channel commands send absolute channel commands, so the upper and lower limits must be programmed into Constant:A and Constant:B. (Default is 0 -> 10.)

(Keyboards B and E combine channel keys with “On” keys.)

•OPT7 handshake mode and power on panel connection blink codes available.
