Serial ports

c
Primary and Secondary RS-232/RS-422 ports — For systems consisting of
a single switcher or for BME 0 on a multi-BME system, connect host devices
(such as computers or touch panel control systems) or MCP 1000 remote
control panels (see the MCP 1000 Remote Control Panel User Guide) to the
Primary and Secondary RS-232/RS-422 ports (figure 2-4). These 9-pin D
connectors provide for serial RS-232/RS-422 control of the matrix switcher.
Figure 2-5 shows how to wire the connectors.
Both ports are connected to both controller circuit cards; a redundant
controller is not required to use the Secondary RS-232/RS-422 port.

After the BMEs have been virtualized, the system can be controlled through
this connection using the PC or other host system that can generate the proper
commands.
The Matrix 12800 Switchers are factory configured for RS-232 control. To use
the switcher under RS-422 control, you must change an internal DIP switch.
See chapter 6,
The default communications rate is 9600 baud. Baud rates of 19.2, 38.4, and
115 are also available. See chapter 6,
If equipped with a redundant controller, the primary and redundant controllers
must be configured for the same communications protocol and transfer rates.
