1.4 Component Identification
The following illustrations and definitions depict some of the more commonly
accessed Galaxy

sign components. Because Daktronics occasionally alters standard
design to meet customer needs, the actual display design may vary slightly from the
illustrations below.
This is only a brief overview. Refer to
Section 4 for detailed information on
maintaining and troubleshooting various sign components.
Com Port:
The serial connector on the back of the control computer. The COM port
controls the sign through a 9 serial connector.
Controller: The display’s controller is 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.

Display Address:
The display address is an identification number assigned to each
display of a network. Rotating the address switches on the controller sets the display
address. 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:
The driver is a 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
module.
