Introduction
1.5 Daktronics Nomenclature
Figure 4: Module Numbering Example – 24x80 Front
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.
A module is the building block of the display. Each
module measures 8 pixels high by 8 pixels wide. By
placing modules side-by-side and on top of one
another, Daktronics can design and build displays of
any size.

illustrates how Daktronics
numbers modules on a Galaxy

display.
Figure 5
breaks down the module numbering method.

In addition, various Daktronics drawings may
contain the following labeling formats:
•
“TB_ _” shows a termination block for
power or signal cable.
•
“F_ _” denotes a fuse.
•
“E_ _” signifies a grounding point.
•
“J_ _” stands for a power or signal jack.
•
“P_ _” represents a power or signal plug for the opposite jack.
Finally, drawings commonly have Daktronics part numbers. You can use those part
numbers when requesting replacement parts from Daktronics Customer Service.
Take note of the following part number formats:
•
“0P-_ _ _ _-_ _ _ _” gives the form of an individual circuit board, such as a
module driver.
• “
0A-_ _ _ _-_ _ _ _” represents an assembly, such as a circuit board and the
plate or bracket to which it mounts. A collection of circuit boards working
as a single unit may also carry an assembly label.
•
“W-_ _ _ _” indicates a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true of ribbon
cables.
Most circuit boards and components within this sign carry
a label that lists the part number of the unit. If the
Replacement Parts List in Section 4.17 does not list a
circuit board or assembly, use the label to order a
replacement.

illustrates a typical label. The part
number is in bold.
