Rxd | Epson JED T440 specs

InFocus projectors (Code 58 hex) (also ASK/Proxima A1100/A1200/A1300)

Currently only IN2102/EP, IN2104/EP and IN2106/EP, but possibly will drive other similar units.

In the back of each user’s manual is a list of typical channel selection messages, and manuals of InFocus projectors are available at: http://www.infocus.com/support.aspx , enter projector model number into the “Projector QuickFind” window to get to an individual model’s page, and click the “documents” tab for codes.

Channel codes are:

Computer1	:= '(SRC0)';	// DSUB1 VGA analog-RGB
Computer2	:= '(SRC1)';	// DSUB2 VGA analog-RGB
Video1	:= '(SRC2)';	// Comp Video
Video2	:= '(SRC3)';	// S-Video

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.)

•The current projectors supplied in Australia MUST HAVE A SOFTWARE UPGRADE BEFORE INSTALLATION from 1.01 to 1.07 or later, otherwise operation is unreliable (comms hangs up) and handshake response requests are incorrectly interpreted as a “power down” command, due to a firmware bug in the projector;

•On panel connection blink codes and OPT7 handshake mode are available;

•Freeze command is available, so “Code A” keyboard OK;

•Two-yellow button “Mute” command is supported;

•The projector is set to Auto Source = 0 (Off) automatically from the T440 by a command string; and

•There is about a 10 second delay after pressing OFF before the lamp goes out and “Cooldown” starts.

RS232 connections to InFocus only IN2102/EP, IN2104/EP and IN2106/EP with D9

These use a 9-pin-D9 male on the proj, female on cable. Comms is at 115,200 baud, 8 bits, no parity, 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.
