CConnect 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 RS-232/RS-422 control. See chapter 3, Operation; chapter 4, Programmer’s Guide; and chapter 5, Matrix Software for details.

RS-232/RS-422 connection

e RS-232/RS-422 connector — Connect a host device, such as a computer, touch panel control, or RS-232 capable PDA to the switcher via this 9-pin D connector for serial RS-232/RS-422 control (figure 2-5).

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.

NThe 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 on page 3-33, 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 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.
