The TNMC controller, located on the rear-access panel, receives signal directly from
the control console and sends data to the modules. Refer to the signal summary in
Section 6.3 for more information and to Drawing A-257029 for the location of the
controller board in the TNMC. The controller itself is detailed in Drawing A-
166216 , and Figure 12 below illustrates a typical controller assembly. The card and
transformer are mounted to a tray, which in turn is mounted to the back panel of the
TNMC cabinet.
Note: That connectors J25 and J26 control Home and Guest display. When the
ribbon cable is plugged is plugged into J25, the TNMC sends home team
information to the matrix display. In the opposite message center, the signal cable
would be plugged into the J26 connector, and guest information would be displayed.
(Switching the cables reverses the information each message center receives.)
J19 is the connector for the address plug. The address setting for TNMCs will
always be 221. (There may be other settings if the TNMCs are used to display
messages other than team names.)
Diagnostic LEDs
Reference Drawing:

There are seven diagnostic LEDs located on the TNMC controller, six indicating
when the controller is receiving signal, and the seventh indicating power status. Four
of the LEDs, those indicating CAN and RS-232 signal functions, are not used with
the TNMC controller.
