APPENDIX B
Serial Communications Cables
A serial link of RS232 or RS422 enables ASCII communication with the projector so that it
can be controlled remotely from a PC or other controller. From a PC, connect a standard
9-wire RS232 serial cable to the RS232 IN port. Or, for long-distance (>100 ft.) links with
an RS422-compatible PC or controller, connect RS422 cable to the RS422 port.
