See Programming Guide, beginning on page 89, for definitions of the SIS commands
(serial commands to control the switcher via this connector) and Matrix Software,
beginning on page 110, for details on how to install and use the control software.
NOTE: 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 rear panel RS-232/RS-422 port protocol and
baud rate on page 77, to configure the RS-232/RS-422 port from the front
panel.
If desired, connect an MKP 2000 or MKP 3000 remote control panel to the
RS-232/RS-422 connector on the switcher. See the MKP 2000 Remote Control Panel
User Guide or the MKP 3000 Remote Control Panel User Guide for details.
