Daktronics AF-3300-12-RGB/20-R - Manual (Page 11)

Louver: Black plastic shade positioned horizontally above each pixel row. The
louvers increase the level of contrast on the display face and direct LED light.
Mirror: A mirror display is the second display in a Primary-Mirror or Double-Face
configuration. The mirror display does not have a controller. All signal information
to the mirror is received though a signal interconnect cable from the primary.
Module: There are two types of modules in the AF-3300, 12 mm RGB and 20 mm
monochrome red. Each is individually removable from the front of the display.
Module Latch Assembly: This is a device utilizing a sliding retainer bar to hold the
module firmly to the display frame. There are two latches on the 12 mm modules
(refer to
Figure 3 ) and four latches on the 20 mm modules (refer to Figure 4 ). A 1 /
8
"
Hex wrench is used to turn the different latches.

Network: A network consists of multiple displays connected to each other. Up to
240 primary displays can exist on one network.
Pixel: A pixel is a single LED or cluster of LEDs. The number and color of the
LEDs depends on display application.
Power Supply: Converts AC line voltage from the load center to low DC voltage for
one or more module driver boards.
Primary: A primary display is a signal-faced unit or the first display in a Primary-
Mirror or Double-Face configuration. The communication and temperature sensor
input will be connected to this display. The light sensor is also internally mounted in
this display. An interconnect cable will transfer information from the primary to the
mirror display in the Double-Face configuration.
