RS232 Serial Communications
From most computers, connect a
standard RS232 serial
communication cable between the
computer and the projector serial
port labeled
RS232 IN
—this 9-pin
connector is located on the input
panel on the side of the projector.
Then set the projector’s baud rate to
match that of the computer.
Changing the baud rate is done in
the projector’s Communications
submenu. See 3.8, Adjusting System
Parameters and Advanced Controls.
RS422 Serial Communications
Some computers can provide RS422 serial communications (often through a plug-in
adapter or external converter) rather than the more common RS232 standard. RS422
communication has differential “transmits-and-receives” and is generally better
suited for long distances than is RS232 communication. Note that RS422 is not
compatible with RS232—connecting a RS232-compatible PC to RS422 can damage
the equipment at either end. Consult the documentation provided with your PC if
your are unsure.
