RS232 connections to Mitsubishi projectors (see also D9 following)
These use an 8 or 9-pin mini-DIN male on the cable. Comms is at 9600 baud, 8 bits, no parity, and 1 stop.

Plus 9 volt CTS/DTR to projector
NOTE: Mitsubishi use either an 8 or a 9-pin
connector for RS232 (the 9-pin one has some USB
lines, which are ignored in use with the T440).
Mitsubishi in some cases supply an off-the-shelf
mini-DIN 8 to DB9 and a mini-DIN 9 to DB9 cable
called by them the "RS232C" cable.
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.
