Serial Communications Port

If the Matrix 6400 Audio Switcher is the Master BME (BME #0), its RS-232/RS-422 connector may be connected to the serial port output of a Host device such as a computer or control panel. Software control of the switcher is made possible by this connection. A Host serial port connection to the RS-232/RS-422 connector of a Matrix 6400 Audio Switcher is shown in Figure 4-1.A.

The Matrix 6400 Audio Switcher is normally configured for RS-232 control. If it is to be used with an RS-422 device, an internal cable must be moved. The procedure for moving the cable begins on Page 5-2.

The RS-232/422 connector on the Matrix 6400 Audio Switcher is a 9-pin

D female with the following pin assignments:
