RS-232 Serial Communications
From most computers, connect a standard RS-232
serial communication cable between the computer, and
the projector serial port labeled
RS232 IN
. This 9-pin
connector is located on the side Input panel 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
Configuration > Communications
secondary menu.
Refer to
Section 3.8 Adjusting System Parameters and
Advanced Controls
.
RS-422 Serial Communications
Some computers can provide RS-422 serial
communications (often through a plug-in adapter or
external converter) rather than the more common RS-
232 standard. RS-422 communication has differential
"transmits-and-receives", and is generally better suited
for long distances than is RS-232 communication.
NOTE:
RS-422 is not compatible with RS-232-
connecting an RS-232-compatible PC to RS-422
can damage the equipment at either end.
Consult the documentation provided with your
PC if you are unsure.
Changing the baud rate is done in the projector's
Configuration > Communications
secondary menu.
Refer to
Section 3.8 Adjusting System Parameters and
Advanced Controls
.
