Daktronics Galaxy AF-3220 - Manual (Page 29)

Glossary 25
Glossary:
3220: The series name of the display, for example Galaxy AF-3220
Controller: The “brains” of the display. The controller receives signal communication from the computer and sends
the appropriate information to the modules. Messages and schedules may also be stored on the controller.
Display Address: An identification number assigned to each display of a network. The control software uses the
address to locate and communicate with each display. Displays that are on the same network must have different
addresses.
Driver/LED Board: The components of a module. This board is responsible for the on/off and intensity levels of the
LEDs.
Galaxy ® : The name given to Daktronics LED matrix displays that can be monochrome, tri-color, or RGB.
Light Emitting Diode (LED): A low energy, high intensity lighting unit.
Mirror: The second display in a two-face configuration. The mirror display does not have a controller so it displays
an exact copy of the information on the primary display. All signal information to the mirror is received through an
interconnect cable from the primary display.
Module: The board containing the LEDs and driver. Galaxy®AF-3220 34 mm modules are 8 pixels high by 16 pixels
wide. Each is individually removable from the front panel of the display.
Network: Multiple displays connected to each other. As many as 240 primary displays can exist on one network.
Pixel: A cluster of LEDs acting as one unit on the module. The number of LEDs in a pixel will depend on display
application.
Primary: A single-face unit or the first display in a primary-mirror (2V) configuration. The communication signal,
light sensor and temperature sensor will be connected to this display. An interconnect cable transfers information
from the primary display to the mirror display so that it shows exactly the same information.
Venus ® 1500 software: Name of Daktronics software that is used on the control computer to communicate with
these displays. This software can create messages and send them to the displays, schedule messages, and perform
diagnostics. The Venus
® 1500 software manual is included on the installation disk.
