CAUTION Connect the sleeve to ground (Gnd). Connecting the sleeve to a
negative (-) terminal will damage the audio output circuits.
By default, the audio output follows the video switch. Audio breakaway,
commanded via the front panel, under RS-232/422 control, or Windows-
based control program, allows you to select from any one of the audio input
sources. See chapter 3, Operation, chapter 4, Programmer’s Guide, and
chapter 5, Matrix Software for details.
RS-232/422 connection
6 Remote/RS-232/RS-422 port — Connect a host device, such as a computer or
touch panel control, to the CrossPoint Plus via this 9-pin D connector for
serial RS-232/RS-422 control (figure 2-6).

If desired, attach an MCP 1000 remote control panel master unit to the
switcher’s RS-232/RS-422 connector. You can also attach 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, part # 68-456-01, and the MKP
1000 User’s Manual, part # 68-355-01, for details.
See chapter 4, Programmer’s Guide, for definitions of the SIS commands and
chapter 5, Matrix Software, to install and use the control software.
The CrossPoint Plus Series Matrix Switchers are factory configured for
RS-232 control. To use the switcher under RS-422 control, an internal cable
must be moved. See appendix B for the procedure for shifting the cable.
