8.3 Glossary
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 for use when desired.
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: A component mounted directly onto the module. This board is
responsible for the on/off and intensity levels of the LEDs.
Galaxy
® : Name is 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.
Louver: A black plastic ledge positioned horizontally above each pixel row. The louvers
block sunlight, thus increasing the contrast on the display face.
Mirror: The second display in a two-sided 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: 34 mm Galaxy
® modules are 8 pixels high by 8 pixels wide. Each is individually
removable from the front of the display.
Network: Consists of multiple displays connected to each other. As many as 240 primary
displays can exist on one network.
Pixel: A single LED or cluster of LEDs. The number and color of the LEDs will depend on
display application.
Primary: A single-faced 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.
The information from these components will be relayed from the primary display to the
mirror display so that it shows exactly the same information. An inter-connect cable will
transfer this information from the primary to the mirror display in this configuration.
Venus 1500: The name given to Daktronics software that is used on the control computer to
create messages and send them to the displays. The Venus 1500 manual is included on the
installation disk.
