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:

Pin	RS-232	Description	RS-422	Description
1	–	not used	Tx(-)	Transmit Data (-)
2	Tx	Transmit Data	Tx(+)	Transmit Data (+)
3	Rx	Receive Data	Rx(+)	Receive Data (+)
4	–	not used	Rx(-)	Receive Data (-)
5	Gnd	Signal Ground	Gnd	Ground
6	–	not used	–	not used
7	–	not used	–	not used
8	–	not used	–	not used
9	–	not used	–	not used

The protocol is 9600 baud, 8-bit, 1 stop bit, no parity and no Flow control.

Details for programming the Matrix 6400 Audio Switcher from a Host system connected to the RS-232/RS-422 port are covered in this chapter.
