Page 7: Components
Components Modules A module is a replaceable unit consisting of a display panel with clusters of LEDs, called pixels. The pixels display messages on the display. Refer to Figure 2. Each module contains drive electronics that receive data packets from the distribution board and lights the appropriate pixels at the correct dimming level. -
Page 8: Panelboard
Panelboard The panelboard is a circuit breaker box that distributes incoming power to the display components that require AC power. Surge Suppressor The parallel surge suppressor protects the display from current spikes. Relays Relays are solid-state switches in which the electrical current applied across one port or terminal controls electrical currents for another terminal, such as a beacon, heater, or fan. -

Traffic Cabinet Mounting Ground Mount Secure the traffic cabinet to a concrete pad using anchor bolts. Daktronics recommends using " stainless steel anchor bolts. When anchoring the traffic cabinet to the concrete pad, make sure the bottom of the cabinet allows for water drainage. Do not seal the cabinet to the concrete pad as this prevents water from draining properly. -
Page 13: Electrical Installation
Electrical Installation Getting Started Daktronics recommends that a separate circuit be run to the electronic display(s) to isolate it and prevent any issues that could be caused by line voltage fluctuations or high frequency noise on the power line caused by other types of equipment. A separate circuit also makes display maintenance and troubleshooting easier. -
