NOTES: 1) Optional digital interfaces cannot be used in a Marquee Case/Power
Supply.2) See Appendix F, Optional Input Modules for a brief description of each
interface.
The most common method of controlling the projector is via one of its keypads. As
an alternative, you may wish to communicate using a PC or similar controller. Such a
device sends commands and receives feedback via serial links (2 types), 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 the remote keypad by cable to the
remote phono jack input at the back of the projector.

RS232 Serial Communications
From most computers, connect a standard RS232 serial communication cable
between the computer and the projector serial port labeled
connector is located on the input panel at the rear of the projector (Figure 2.28). In
the Communications menu, set the projector's baud rate (default = 115200) to match
that of the computer.
Figure 2.28. RS232 Serial Communications
Changing the baud rate is done in the projector's Communications submenu. See 3.7,
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 you
are unsure.
