Components
2.3 Control Panel
The control panel is located in the right
side of the display.
components make up the control panel.
These components use information
received from the VFC-3000 controller to
operate the display.
CAN Distribution Board
The CAN distribution board receives high-
speed serial data from the VFC-3000
controller through a fiber-optic or Cat-5
cable. It then distributes the signal to the
appropriate modules and sensors. The
CAN distribution board receives
diagnostic data from the modules,
temperature sensors, light sensors, LVDBs,
and CAN I/O board and transmits the
data to the VFC-3000 controller.
The distribution board uses a protocol that
routes signal to each horizontal line of the display. With this protocol, signal failure to one
module in a horizontal line does not affect other LED modules in that line.
CAN I/O Board
The CAN I/O board is an input/output interface that also monitors the status of the power
supplies, door open sensors, control beacons, fans, and heaters.
DC / DC Converter Board
The DC / DC converter board converts the 24 VDC output of the power supplies to 9 VDC.
The power is then used by the light and temperature sensors, CAN distribution board, CAN
I/O board, sensors, and LVDBs within the display.
2.4 Panelboard
The panelboard is a circuit breaker box that distributes incoming power to the fans, DC / DC
converter, and outlets.
2.5 Surge Suppressor
The parallel surge suppressor protects the display from current spikes.
