After installation wiring of any projector to a T460, 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.

The following table shows the mapping of T460 channel number, the string sent, and the input associated with that channel in
the manual, and how it is identified on the on-screen menu:
T460 Channel TX codes bytes 6,7,8 Input name in manual Function as identified on screen
1 0Dh, 0C4h, 0D4h RGB RGB
2 094h, 0C4h, 0DDh DVI DVI
3 0DCh, 0C5h, 0D5h Video Video
4 0A7h, 0C4h, 0DEh S-Video S-Video
Don’t forget to set all unused T460 channels to “Skip” to jump over blank/unused inputs.
You will need to disable the “Auto Source” function in the projector so it accepts remote RS232 commands. Not doing
so will allow the projector to seek a signal (on, say a Video source) when the PC source drops out), and it ignores serial
commands. This is the first item in the “Setup” (third) menu.
