capability. The voltage levels of this signal can damage incompatible equipment.
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 longer distances than RS232 communication. NOTE: RS422 is
NOT compatible with RS232. Connecting an RS232, compatible PC to RS422 can damage the equipment at
either end.
The 9-pin RS422 connector is located on the back panel of Christie ACT, refer to Figure 2-17. When using the
port, ensure that the baud rate matches that of your RS422 controlling device. Refer to
