DELL projectors (Code 4D hex)
This family has many members with a range of channel messages. Most just support a VGA, a Composite and an S-
Video input. Some have HDMI
Models covered are 1200MP, 1201MP, 1209S, 1409X, 1510X, 1609WX, 1610HD, 1800MP, 2400MP, 4100MP,
4210X, 4220, 4310X, 4320, 4610X, 5100MP, 7609WU, S300/W/WI, S500wi.
In the back of each user's manual is a list of typical channel selection messages. These are accessible at:

anavml (Then select "Choose a model", then "Electronics", then "Projector", then a particular model.)
Channel codes are:
Input1 := BE + EF + 10 + 05 + 00 + CC + FF + 11 + 11 + 01 + 00 + 19; //Computer1 VGA RGB1 Analog (all)
Input2 := BE + EF + 10 + 05 + 00 + CF + 3F + 11 + 11 + 01 + 00 + 1C; //Computer2 M1 ANALOG DVI connector
Input3 := BE + EF + 10 + 05 + 00 + DF + 7F + 11 + 11 + 01 + 00 + 23; //Video1 Composite Video RCA
Input4 := BE + EF + 10 + 05 + 00 + 3A + 3E + 11 + 11 + 01 + 00 + 50; //Video2 HDMI 1*
* T440: OPT6 switch ON will use S-Video in place of HDMI/DVI. (OPT1 swaps Video1 & Video2)
T430: Uses HDMI as Video2
Input5 := BE + EF + 10 + 05 + 00 + DE + 3F + 11 + 11 + 01 + 00 + 20; // YPbPr via RCA
Input6 := BE + EF + 10 + 05 + 00 + CD + BF + 11 + 11 + 01 + 00 + 1A; // VGA Component (1200MP, 1201MP,
Input7 := BE + EF + 10 + 05 + 00 + 28 + FE + 11 + 11 + 01 + 00 + 69; // VGA RGB2 Analog (1209S, 7609WU)
Input8 := BE + EF + 10 + 05 + 00 + 0F + FE + 11 + 11 + 01 + 00 + 1D; // M1 Digital DVI (4100MP, 5100MP)
Input9 := BE + EF + 10 + 05 + 00 + 3A + 3E + 11 + 11 + 01 + 00 + 50; // HDMI 1
Input10 := BE + EF + 10 + 05 + 00 + E9 + 7F + 11 + 11 + 01 + 00 + 6B; // HDMI 2
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. Setting OPT5 will
swap Computer1 and Computer2. Setting OPT4 will allow double- presses on some keyboards.).
No OPT7 handshake mode and power on panel connection blink codes are available, as no status read-back;
•
Mute is toggle, and is only available on code A keyboards;
•
FREEZE is supposed to be supported on some, but tested codes do NOT work on a 2400MP. They may work on
•
4100MP/5100MP, but not tested. Thus a Code8 or A keyboard may have a non-functioning Freeze key;
On keyboards with volume keys, incremental Volume up and down is supported. Mute is NOT supported because
•
there is no read-back of mute status. It is not supported in OPT8 T441/T461 mode either, because of no read-back;
(2300MP is not supported, as it has no absolute power on/off commands and no status read-back.)
RS232 connections to DELL projectors.
Communication is at 19200 8N1
To connect the T440 to these projectors use a mini-DIN 6 male on the cable:

Data from T440 to projector
Reply data from projector to T440
Plus 9 volt CTS/DTR to projector
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.
