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.
