8.4 Definitions of Terms
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.
LED (Light Emitting Diode): 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 inter-connect
cable from the primary display.
Module: The board containing the LEDs and driver. Galaxy
® AF-3200 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 will transfer the information from
the primary display to the mirror display so that it shows exactly the same
information.
Venus 1500: Name given to 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 manual is included on the installation disk.
