Daktronics AF-3400-64-R,A - Manual (Page 12)

Louver: Black shade positioned horizontally above each pixel row. The louvers
increase the level of contrast on the display face and direct LED light.
Module: 64mm Galaxy
®
modules are 8 pixels high by 8 pixels wide. They consist of
the louver assembly, two 4x8 pixel boards, and two drivers (refer to Figure 3 ).

Network: Consists of multiple displays connected to each other.
Pixel: Cluster of LEDs. The number and color of the LEDs depends on display
application.
Pixel Board: The pixel board contains the LED clusters, which mount into the metal
face panel. A module driver is attached to the back of each 4x8 pixel board.
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 single-faced unit. The communication and
temperature input will be connected to this display. The light sensor is internally
mounted in this display. If two primary displays are used, the display signal and
temperature information is hardwired from display to display. Route the
interconnect cable through conduit when exposed to outdoor conditions.
1.5 Daktronics Nomenclature
To fully understand some Daktronics drawings, such as schematics, it is necessary to
know how those drawings label various components. This information is also useful
when trying to communicate maintenance or troubleshooting efforts.
