Definitions of Terms
Controller: The “brains” of the display. The controller receives signal communication from the
computer and sends the appropriate information to the MLC. 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: The LEDs are mounted directly onto the module. This board is also responsible
for the on/off and intensity levels of the LEDs.
GalaxyPro
® : Daktronics trademarked name for LED RGB matrix displays.
LED (light emitting diode): A low energy, high intensity lighting unit.
Louver: Black plastic ledge positioned horizontally above each pixel row. The louvers block sunlight,
thus increasing the level of 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 GalaxyPro
® modules are 8 pixels high by 8 pixels wide. Each is individually
removable from the front of the display.
Multi-line Controller (MLC): a component that distributes signal from the controller or another MLC
to a number of modules.
Network: Consists of multiple displays connected to each other. As many as 240 primary displays
can exist on one network.
Pixel: A cluster of red, green, and blue LEDs.
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: Name given to the software on the control computer that is used to create messages and
send them to the displays. The Venus 1500 manual is included on the installation disk.
