Epson JED T440 user manual Sharp, Eiki EIP projectors Code 20 hex, absolute audio

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.
