Serial Communications Port
___ The Matrix Wideband Video Switcher is normally configured for RS-232 control.
4-1
If the Matrix Wideband Video 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 Wideband Video Switcher is shown in Figure
4-1.A (top BME = Matrix 3200 Wideband Video Switcher, bottom BME = Matrix
6400 Wideband Video Switcher).
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 5-1.
The RS-232/422 connector on the Matrix Wideband Video Switcher is a 9-pin
D female with the following pin assignments:
