Epson VP21 projectors (Code 0C hex)
This family has many members with a range of channel messages.
Typical models are: EMP 30/52/53/54/61/73/74/81/62/82/83/400W/600/800/810/811/820/821/822/828/830/835/830 /
EMP 6100/6000/6110/1810/1815/1825/7800/7850/7900/7950/8300/9300/S1/S1H
In the back of each user’s manual is a list of typical channel selection messages,
Channel codes are:
Computer1 := 'SOURCE 11' + 0D; // DSUB1 VGA analog-RGB
Computer2 := 'SOURCE 21' + 0D; // DSUB2 VGA analog-RGB
Computer3 := 'SOURCE 30' + 0D; // INPUT3 DVI-D
Computer4 := 'SOURCE 31' + 0D; // INPUT3 D-RGB
Computer5 := 'SOURCE B1' + 0D; // INPUT4 BNC analog-RGB
Video1 := 'SOURCE 41' + 0D; // Comp Video
Video2 := 'SOURCE 42' + 0D; // S-Video
Video3 := 'SOURCE 14' + 0D; // Component on DSUB1 or YCbCr on DSUB1
Video4 := 'SOURCE 24' + 0D; // Component on DSUB2 or YCbCr on DSUB2
Video5 := 'SOURCE 15' + 0D; // YCbCr on DSUB1
Video6 := 'SOURCE 25' + 0D; // YCbCr on DSUB2
Video7 := 'SOURCE 30' + 0D; // INPUT3 DVI-D
Video8 := 'SOURCE 31' + 0D; // INPUT3 D-RGB
Video9 := 'SOURCE B2' + 0D; // INPUT4 BNC COMPONENT RGB-Video
Video10 := 'SOURCE B3' + 0D; // INPUT4 BNC COMPONENT YCbCr
Video11 := 'SOURCE B4' + 0D; // INPUT4 BNC COMPONENT YPbPr
Video12 := 'SOURCE C4' + 0D; // INPUT5 BNC COMPONENT YCbCr
Video13 := 'SOURCE C5' + 0D; // INPUT5 BNC COMPONENT YPbPr
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.)
• OPT7 handshake mode and power on panel connection blink codes available.
