NOTES: 1) Optional digital interfaces cannot be used in a Marquee Case/Power
Supply. 2) Refer to Appendix D, Optional Input Modules for a brief description of
each interface.
As an alternative to the projector's keypad or remote, you may wish to communicate
with the projector using a PC or other controller. Such a device sends commands and
receives feedback via serial links (RS-232 and RS-422), Ethernet or GPIO
communications to the projector, all described below.
As desired, direct the projector's IR remote keypad towards the display screen or the
projector's IR sensors. Alternatively, connect a wired (tethered) version of the remote
to the 3.5mm RCA jack labeled as
response to a wired keypad must also be enabled in the Communications menu—
Refer to 3.6, Adjusting System Parameters and Advanced Controls for more
information.
There are two types of serial ports available on the projector: RS-232 and RS-422.
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 nine-pin DIN connectors labeled RS-232 IN and RS-232 OUT on the input
panel are dedicated to serial communication (see Figure 2.28). Using the appropriate
serial communication cables (refer to Appendix B) connect the controlling source,
such as a personal computer to the RS-232 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. (Figure 2.28) RS-422 is better suited
for serial communication over long distances then is RS-232 communication.
