Page 9: Components
Section 2: Components 2.1 Modules A module is a replaceable unit consisting of a display panel with clusters of LEDs, called pixels, and a driver board. The pixels show messages on the display face. Refer to Figure 2. Each module contains drive electronics that receive data packets from the distribution board and light the appropriate pixels at the correct dimming level. -
Page 10: Control Panel
Control Panel The control panel is located on the right side of the display. Figure 4 shows what components make up the control panel. These components use information received from the VFC-3000 controller to operate the display. Figure 4: Control Panel 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. -
Page 11: Can I/O Board
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. -
Page 12: Bottom Sensor
Bottom Sensor The bottom light sensor is located on the bottom-right of the display. It detects the light intensity below the display. Left-End Sensor (Optional) The left-end sensor measures the internal temperature. The sensor transmits these measurements to the CAN distribution board, and the VFC-3000 controller adjusts LED intensity to protect the LEDs from overheating. -
Page 13: Beacon(S) (Optional)
2.10 Beacon(s) (Optional) Beacons are turned on and off independently from the rest of the sign by the CAN I/O board. The CAN I/O board interfaces with the beacon control panel (BCP), located on the rear wall. A power supply and DC relays are located within the BCP. Beacons are used only during certain messages, such as emergencies or warnings, as an extra measure of alert. -
Page 14: Cabinet Heater (Optional)
Cabinet Heater (Optional) If equipped, the heater fan is located at the bottom of the traffic cabinet. The fan, thermostat, and heater regulate the temperature within the traffic cabinet; ensuring internal components operate at ideal temperatures. UPS (Optional) A UPS contains batteries and an inverter. If the utility AC power fails, the UPS powers the VFC-3000 controller and communication equipment for a limited amount of time. -
Page 15: Mechanical Installation
The eyebolts are designed to carry only the weight of the display cabinet. Do not lift the mounting structure or other additional weight. Do not permanently support the display with the eyebolts. Contact Daktronics with additional questions about display lifting. Figure 5: Correctly Lifting the Display 3.2 Setting the Display on the Ground... -
