HP xp8010 manual: http://h10032.www1.hp.com/ctg/Manual/bpq04040.pdf
Channel codes are:
Computer1 := '*RSRC=1' + 0D; // VGA1 Analog RGB DB15 vp632x, xp802x, Code 48
Computer2 := '*RSRC=2' + 0D; // VGA2 Analog RGB DB15 on xp8010/20, Code 48
Computer3 := '*RSRC=6' + 0D; // RGBHV xp8010/20, Code 48
Computer4 := '*RSRC=7' + 0D; // M1 Graphics (DVI) xp8010/20, Code 48
Computer5 := '*RSRC=8' + 0D; // DVI vp63xx, not analog, Code 48
Computer1 := '*RSRC=8' + 0D; // VGA1 Analog RGB via DVI to DB15 adaptor (ep712x, Code 49)
Video1 := '*RSRC=3' + 0D; // Composite Video RCA all
Video2 := '*RSRC=4' + 0D; // S-Video all
Video3 := '*RSRC=5' + 0D; // Component Video YPbPr xp632x/xp8010/20
Video4 := '*RSRC=6' + 0D; // RGBHV xp8010/20, Code 48
Video5 := '*RSRC=7' + 0D; // M1 Graphics (DVI) xp8010/20, Code 48
Video6 := '*RSRC=8' + 0D; // DVI vp63xx, not analog, Code 48
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).
• Setting OPT2 switch ON will send an Auto Pixel Align message 30 seconds after selecting a computer channel;
• Pressing a “Computer” channel key when already selected will instead send a Auto Pixel Align whenever needed;
• For ep712x use Code 49 on the Sw2/3, and use DVI-> VGA connector. (No computer 2.)
• OPT7 handshake mode and power on panel connection blink codes available.
RS232 connections to Hewlett-Packard vp63xx, xp80xx, (probably also ep712x)
These use a 9-pin-D9 male on the proj, female on cable. Comms is at 9600 baud, 8 bits, no parity, and 1 stop.

After installation wiring of any projector to a T440, use a multimeter to check voltages of –9 on BOTH TX and RX pins
in any installation, as described in the troubleshooting part of this manual.
