The control card (part number 400.100.1004)
coordinates and reports actions
within the Matrix-Hub. It provides the user interfaces, initiates connections
between cards, and stores macros and other connectivity shortcuts in memory.
There are two DB9 connectors on the control card; one is male, while the other is
female. The user may access the Matrix-Hub user interface through the female
connector (labeled “IN”); the male connector (labeled “OUT”) has not been
implemented yet.
The IN port baud rate for the control card’s serial port and other options are
changeable using DIP switches mounted on the surface of the control card. The
user may alter the settings by removing the card from the chassis and turning the
switches on or off according to the tables in Appendix A, Control Card Settings.
See section 8.0, User Interface and section 7.0, Electroluminescent Display for
more information on using the control card and its interfaces.
