1.4 Component Identification
The following illustrations and definitions depict some of the more commonly
accessed Galaxy
®
display 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 display components.
Com Port: Connector on the back of the control computer. The COM port controls
the sign through a 9-pin serial connector.
Controller: The display’s controller is the “brains” of the display (refer to Figure 2 ).
The controller receives, translates, and activates the signal information from the
control computer to the appropriate pixels on the display.
Figure 2: Controller
Display Address: The display address is an identification number assigned to each
display of a network. It is set by rotating hex 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. One
driver mounts on the back of each 4x8 board of an 8x8 module.
Galaxy
® : Daktronics trademarked name for LED monochrome or tri-colored matrix
signs.
LED (light emitting diode): Low energy, high intensity lighting units.
