Appendix A: Serial Communication Cables
A.1 Serial Links to Projector
A.1.1 General Communications
A serial link of RS-232 or RS-422 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 RS-232 serial cable to the RS232 IN port
located on the side of the projection head. Or, for long-distance (>100 ft.) links with an RS-422-compatible PC or
controller, connect RS-422 cable to an RS422 port located on the side or rear panel of the projection head.
A.1.2 Software Downloads
Downloading new software to the projector requires RS-232 or RS-422 connected to the 9-pin connectors on the side
of the projector only—do not download using either of the 6-pin XLR RS-422 ports located at the rear of the projector.
NOTE: Using a rear RS-422 port (6-pin XLR) or Ethernet link for downloading new software to
the projector is not supported.
A.1.3 RS-422 Connections
Depending on your RS-422-compatible device or RS-232 – RS-444 converter, the cabling wiring can vary, and may
require a custom cable. There is no single standard pinout for RS-422.
