Daktronics AB-1600-1.5,2.5 - Manual (Page 12)

Introduction 1-6
Single-Face Display: A single-sided, independent display, as seen in Figure 9.
Starburst Display: Refers to one of the two types of
displays available (SunSpot is the other). Starburst color
displays use blue, red, green and white lenses. These lenses,
combined with the proper display controller, can create 16
color or 16.7 million color images on a display. Starburst is
a registered trademark of Daktronics.
Sunspot Display: A monochrome display capable of 64
shades of gray when used with the proper display controller.
Sunspot is a registered trademark of Daktronics.
Temperature Sensor: A device mounted separately from the display that reports temperature
information to a controller for processing and display. Refer to ED-9489 and Drawing A-79767
in Appendix C for temperature sensor installation information.
Line Receiver Definitions
The following definitions are specific to displays
with line receivers.
Line Receiver: Sometimes called a serial line
interface, a line receiver receives signal from the
controller computer through fiber optic cable and
routes it to the display through vertical shift boards.
A line receiver is capable of producing
monochrome or 16 color images. Figure 10 shows
a line receiver.
Vertical Shift Board: The vertical shift board is a
circuit board mounted to the back of the left-most
(front view) lampbank in each row of modules. It
routes data from the line receiver both down the row
and to the vertical shift board below it. Figure 11
shows a vertical shift board.
Data Distributor Definitions
The following definitions are specific to displays with data
distributors.
Column Director: This circuit board directs the flow of data
coming from the data distributor to the proper line controller(s)
through RJ45 cable. It is part of the interface for 16.7 million-
color and 64 shades of gray technology.
Data Distributor: The data distributor is a display controller
that consists of a receiver board and output cards. The number of
output cards can range from 2 to 10, depending on the size of the
