Channel codes are:
Computer1 := '* 0 IR 015' + 0D; // RGB analog-RGB VGA
Computer2 := '* 0 IR 028' + 0D; // RGB analog- via DVI (some models only)
Computer3 := '* 0 IR 016' + 0D; // DVI digital via DVI
Video1 := '* 0 IR 019' + 0D; // Comp Video
Video2 := '* 0 IR 018' + 0D; // S-Video
Video3 := '* 0 IR 017' + 0D; // Component YPbPr via DB15 HDTV
Video4 := '* 0 IR 029' + 0D; // Component YPbPr DVI or HDMI via adaptor (some models only)
Video5 := '* 0 IR 016' + 0D; // DVI or HDMI via adaptor
(There may be more codes available for “Wireless” and “HDMI” on newer devices. Update later.)
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, making S-Video the video default.)
• Power on projector connection blink codes available;
• OPT7 handshake mode not available;
• Source lock must be turned ON in the “Maintenance” menu;
• Freeze and mute are toggle mode only in these projectors, so 2-yellow-button mute mode is NOT supported;
• Audio functions are limited to one (sometimes two) audio input(s) and no output to room speakers. Use a T461 if
audio control is needed.
