CAUTION
Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative
(-) terminal will damage the audio output circuits.
The volume level for each output can be individually set via the front panel or
Ethernet or RS-232/RS-422 control. See chapter 3, Operation, chapter 4,
Programmer’s Guide, chapter 5, Switcher Software, and chapter 6, HTML
Operation for details.

See chapter 4, Programmer’s Guide, for definitions of the SIS commands (serial
commands 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 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 configure the RS-232/RS-422 port from the front panel.
