NOTE: Communication software is required for serial control. Contact your dealer.
You may wish to use equipment other than the keypad for controlling the projector or
for performing other special functions. Such equipment—such as most personal
computers—requires a serial interface for sending and receiving communications
through the serial ports on the projector. Note that there are two different types of
serial communication ports on this projector as described below.
RS-232 Ports
'
From most computers, connect an
computer and the projector serial port labeled
is located near the bottom center of the projector's rear control panel (see Figure
2.23). Then set the projector baud rate to match that of the computer (changing the
baud rate is described in 3.7, Configuring System Parameters).
NOTE: Refer to Appendix D for complete cable wiring details.

Some computers can provide
adapter or external converter) rather than the more common RS-232. RS-422
communication has differential "transmits-and-receives" and is generally better
suited for long distances than is RS-232 communication. RS-422 is not compatible
with RS-232—connecting one to the other could damage the equipment at either end.
If you wish to control the projector with a computer and/or other controlling device
(such as the Two-Way Controller) having RS-422 capability, connect
communication cables between the computer (or other device) and either (or both) of
the projector serial ports labeled
located near the upper right corner of the projector's rear control panel (see Figure
