Theory of Operation
The Daktronics VFC-3000 controller is the communication hub for DMS management; it
is located in the display or in the traffic cabinet. The central controller creates messages
and transmits them to the VFC-3000 controller for storage. Upon request from the central
controller or the front panel interface, the VFC-3000 controller locates the message
to play and sends it to the display’s modules via the distribution board. The modules
activate the appropriate pixels to form the message.
