commands to control the switcher via this connector) and chapter 5, Matrix
Software, for details on how to install and use the control software.
N The switcher can support either the 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 confi gure the RS-232/RS-422 port from the front panel.
If desired, connect an MKP 2000 or MKP 3000 remote control panel to the
switcher’s RS-232/RS-422 connector. Refer to the MKP 2000 Remote Control
Panel User’s Manual and the MKP 3000 User’s Manual for details.
