Daktronics AF-3180-64-R,A - Manual (Page 8)

Figure 1 below illustrates Daktronics drawing label. The lower-right corner of the
drawing contains the drawing number. The manual identifies the drawings by listing
the last set of digits and the letter preceding them. In the example below, the manual
refers to the drawing as Drawing A-69945. Appendix A contains all reference
drawings.
Figure 1: Drawing Label
This manual shows all references to drawing numbers, appendices, figures, or other
manuals in bold typeface, as shown below:
“Refer to Drawing A-69945 in Appendix A for the power supply location.”
Additionally, the manual lists drawings referenced in a particular section at the
beginning of that section as seen in the following example:

Daktronics builds displays for long life and that require little maintenance. However,
from time to time, certain sign components need replacing. The Replacement Parts
List in Section 4.13 provides the names and numbers of components that may need
to be replaced during the life of the sign. Most sign components have a white label
that lists the part number. The component part number is in the following format:
0P-_ _ _ _-_ _ _ _ (circuit board) or 0A-_ _ _ _-_ _ _ _ (multi-component assembly).
Following the Replacement Parts List is the Exchange and Repair and Return
Programs in Section 4.14. Refer to these instructions if any sign component needs
replacement or repair.
1.2 Network Concepts
The concept of using LED displays as cost effective, high impact method of
communication is rapidly growing throughout many industries and businesses. The
reasons for this growth are many, but the need for additional features and complexity
of multiple display installations has emerged. Daktronics display systems have been
designed to meet those needs.
The common thread to most client requests is a means of programming and
controlling a group of displays from a central control point. Daktronics responded by
developing a powerful system of interconnecting and controlling displays. Great care
has been taken to design products that will satisfy a wide variety of installations.
Some of the design goals of these systems include the following:
• Easy transfer of messages
• The ability to tell a display or group of displays in the network which
message should run
• The ability to determine the status of any display on the network
• The ability to control multiple display technologies on the same network
