Controller: The “brains” of the display. The controller receives, translates, and
activates the signal information from the control computer to the appropriate pixels
on the display accordingly.
Figure 2: Controller
Display Address: The display address is an identification number assigned to each
display of a network. The address is set using DIP switches on the controller. The
control software uses the address to locate and communicate with each display.
Displays that are on the same network
cannot have the same address.
Driver: Circuit board responsible for switching the intensity levels of the LEDs. The
driver is located inside the driver box and mounts on the back of the modules.
Fiber Optic: Technology that uses glass (or plastic) threads (fibers) to transmit data
from the controller to the display. A fiber optic cable consists of a bundle of glass
threads, each of which transmits messages modulated onto light waves.

: Daktronics trademarked name for LED monochrome or tri-colored matrix
signs.
Jumper: A jumper is a metal bridge that closes an electrical circuit. In most cases, it
consists of a black plastic plug (with metal wires inside) that fits over a pair of
protruding pins. By placing the jumper over a set of pins, the user can change the
board’s parameters.
Latch Access Fastener:
Device utilizing a rotating retainer bar to hold the module
firmly to the sign frame. There are two per module: one near the top center of the
module and another on the bottom center.
LED (light emitting diode): Low energy, high intensity lighting units.
Louver:
Black shade positioned horizontally above each pixel row. The louvers
increase the level of contrast on the sign face and direct LED light.
