APPENDIX
Matrix Switch Communication Protocol
The RS-232/RS-485 communications are half-duplex with variable byte
count packets. For RS-232, the matrix switch operates as a DCE device
and therefore can be connected using a straight cable to a DTE device
such as a computer. The RS-232 connector is a DB-9 female. For RS-485, a
discrete wiring connector is provided for custom connection to any
RS-485 equipment. For full details on connecting to the matrix switch refer
to the User Manual.
