Swapping the RS-232/RS-422 Port cable

2-7
The Matrix 200 can be controlled by a host system through an RS-232/RS-422
interface. The interface allows the user to write programs to configure and
automate the operation of the Matrix 200. This includes making changes
dynamically when commanded by the host controller and when informing the
host of the Matrix status. Certain important changes in status are reported to the
host automatically. For additional programming information, refer to Appendix B.
The RS-232/RS-422 connector is a standard 9-pin D subminiature female
receptacle with the following pin designations:

The RS-232/RS-422 baud rate is selectable from the Miscellaneous Menu, see
Chapter 4. The default protocol is 9600-baud, 8-bits, no parity, 1 stop bit, X-On/
X-Off.
The rear panel of the matrix has a single 9-pin connector labeled "RS-232". The
Main Controller board provides two connectors – one for RS-232 and the other
for RS-422. Each matrix ships with the cable connected to the RS-232 port on
the Main Controller board. If your system uses RS-422, you may change this
connection on the Main Controller board as shown below. See page 2-2 for
instructions on removing the Matrix 200 cover.
