See chapter 4, Programmer’s Guide, for definitions of the SIS commands (serial
commands that you can use to control the switcher via this connector) and
chapter 5, Matrix Software for details on how to install and use the control
software.
The switcher can support either RS-232 or RS-422 serial communication
protocol, and operate at 9600, 19200, 38400, or 115200 baud rates.
See Selecting the RS-232/RS-422 protocol and baud rate in chapter 3,
Operation, to configure the RS-232/RS-422 port from the front panel.
If desired, connect an MCP 1000 remote control panel master unit to the
switcher’s RS-232/RS-422 connector. You can also connect an MKP 1000
remote keypad or MCP 1000 slave unit to the MCP 1000 master unit. Refer to
the MCP 1000 Remote Control Panel User’s Manual and the MKP 1000 User’s
Manual for details.
