VFC-3000 Controller
The 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 display and sends it to the display’s modules via the
distribution board. The modules activate the appropriate pixels to form the message.
The VFC-3000 controller also monitors local sensors (display-based sensors) like temperature,
light level, and door detection. The VFC-3000 controller interprets sensor data for display
control and diagnostic functions, such as adjusting the display’s intensity for current lighting
conditions.
Auxiliary Control Panel (Optional)
The auxiliary control panel (ACP) complements the VFC-3000 controller by providing a
secondary control interface panel at the DMS site. The ACP allows a maintenance technician
to perform diagnostics while working in one location without having to access the VFC-3000
controller in another location. This improves safety and reduces maintenance time.
1.4 Display Peripherals
A peripheral is a display component configured through the VFC-3000 controller. Peripherals
include sensors, power supplies, low voltage distribution boards (LVDB), fans, and heaters.
