There are two types of serial ports available on the projector: RS232 and RS422. You
can connect a device with a serial interface, such as a computer to either of these
connectors (not both) and control the projector remotely by entering specific serial
communication commands.
Connecting RS-232
The two 9-pin DIN connectors labeled RS232
IN and RS232 OUT on the input panel are
dedicated to serial communication. Using the
appropriate serial communication cables
(see
Appendix C)
connect the controlling source,
such as a personal computer to the RS232 IN
connector. Then set the baud rate to match that
of the computer. Refer to
Section 3
for details
on changing the projector’s baud rate.
Connecting RS-422
If you wish to control the projector with a
computer and or other controlling device
with RS-422 capability, connect a RS-422
serial communication cable between the
computer and the RS-422 port on the
projector. RS-422 is better suited for serial
communication over long distances than RS-
232 communication.
Use the RS-422 port only if your device had
RS-422 capability – always consult the
literature provided with your equipment
before connecting. Connecting to the RS-422
port with incompatible equipment could
damage your projector.
