Serial Communications Port
If the Matrix 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 Video Switcher is shown in Figure 4-1.A.
___ The Matrix Video 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 5-1.
The RS-232/422 connector on the Matrix Video Switcher is a 9-pin D female with
the following pin assignments:
