Sharp, EIKI EIP projectors (Code 20 hex, absolute audio)
This family has many members with a range of channel messages.
Sharp has RS232 code charts at the back of the Operation Manual for each projector.
Channel codes are:
Computer1 := 'IRGB 1' + 0D; // RGB 1 VGA analog-RGB
Computer2 := 'IRGB 2' + 0D; // RGB 2 analog, sometimes DVI analog
Computer3 := 'IRGB 3' + 0D; // DVI Analog
Computer4 := 'IRGB 4' + 0D; // DVI Digital
Video1 := 'IVED 1' + 0D; // Comp Video/S-Video / Component 1
Video2 := 'IVED 2' + 0D; // S-Video / Comp Video / Component 2
Video3 := 'IVED 3' + 0D; // Comp Video 2
Video4 := 'IVED 4' + 0D; // S-Video 2
Video5 := 'IVED 5' + 0D; // RGB/COMPONENT on SHARP DT-400, XV-Z2000, EIKI EIP-1500
Video6 := 'IVED 6' + 0D; // DIGITAL MODE on SHARP DT-400, XV-Z2000, EIKI EIP-1500
Video7 := 'ISEV 1' + 0D; // S-VIDEO on EIKI_EIP_S200/X200/X350
Video8 := 'ICMP 1' + 0D; // COMPONENT on EIKI_EIP_S200/X200/X350
Video9 := 'IDVI 1' + 0D; // DVI on EIKI_EIP_S200/X200/X350
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.)
• Some models use IVED 1 for Comp Video, and IVED2 for S-Video, and some use the reverse;
• OPT7 handshake mode and power on panel connection blink codes available.
RS232 connections to Sharp/Eiki projectors
These use a D-sub 9-pin connector, female or male on cable: (May be via an adaptor cable from projector 9-pin mini-
DIN) Communications is at 9600 baud 8N1. Some projectors may need this to be set up via an on-screen menu.

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.
