Epson JED T440 RS232 connections to Sanyo projectors, Control Port Connector, Function/Direction

Sanyo, Eiki projectors (Code 02 hex, absolute audio, Code 03 hex, inc. audio, Code 04 hex, C07 video, Code 05 hex, C05 Computer 1)

This family has many members with a range of channel messages.

Sanyo has RS232 code charts on www.sanyo.com.au listing codes for each projector.

Many Eiki, e.g. LC-SB, SD, SE, SX, W, WB, X (most, but not 3-digit ones), XA, XB, XE, XG, XGA, XT. Not LC-EIP (see Sharp) or XIP2000 or XWP2000 (yet).

Check codes at: http://www.eiki.com/Support/Default.aspx (some older use just C05, C06, C07 codes below).

If absolute audio (Code 02) doesn’t work, use Code 03, which sends incremental audio.

Channel codes are:
Computer1	:= 'C50' + 0D;	// Input 1 Analog RGB DB15
Computer2	:= 'C25' + 0D;	// Input 2 Analog RGB DB15
Computer3	:= 'C52' + 0D;	// Input 1 DVI (PC Digital)
Computer4	:= 'C05' + 0D;	// Input 1 / Slot 1
Computer5	:= 'C06' + 0D;	// Input 2 / Slot 2
Computer6	:= 'C81' + 0D;	// Input 4 / Wired network
Computer7	:= 'C82' + 0D;	// Input 4 / Wireless
Video1	:= 'C33' + 0D;	// Input 3 Composite Video RCA
Video2	:= 'C34' + 0D;	// Input 3 S-Video
Video3	:= 'C35' + 0D;	// Input 3 Y, Pb/Cb, Cb/Cr (Component)
Video4	:= 'C07' + 0D;	// Input 3 / Slot 3
Video5	:= 'C23' + 0D;	// Input 2 Composite Video RCA
Video6	:= 'C24' + 0D;	// Input 2 S-Video/Component RCA
Video7	:= 'C25' + 0D;	// Input 2 Component 1 RCA
Video8	:= 'C26' + 0D;	// Input 2 Component 2
Video9	:= 'C06' + 0D;	// Input 2 / Slot 2
Video10	:= 'C53' + 0D;	// Input 1 DVI (AV HDCP)
Video11	:= 'C54' + 0D;	// Input 1 Component
Video12	:= 'C05' + 0D;	// Input 1 / Slot 1
Video13	:= 'C81' + 0D;	// Input 4 Composite Video / Wired network
Video14	:= 'C82' + 0D;	// Input 4 S-Video / Wireless
Video15	:= 'C83' + 0D;	// Input 4 Component / USB viewer

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).

•Some models (eg PLC-XW55/56) use command C07 for composite video, so use Code 04 hex for these.

•Some models (eg PLC-XU105) use command C05 for Computer:1, so use Code 05 hex for these.

•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;

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