1.5  Daktronics Nomenclature  

To fully understand some Daktronics 
drawings, such as schematics, it is 
necessary to know how various 
components are labeled in those 
drawings. This information is also 
useful when trying to communicate 
maintenance or troubleshooting efforts. 

Introduction 

1-5

 

 
A module is the building block of the 
Galaxy sign. Each module measures 16 
pixels high by 16 pixels wide. By placing modules side-by-
side and on top of one another a sign of any size can be 
designed and built. Individual modules can be easily 
removed from the sign if required. 

Figure 4 

above

 

illustrates how Daktronics numbers modules on a Galaxy 
sign. 

Figure 5 

on the right

 

breaks down the module 

numbering method. 

 

Figure 4: 

Module Numbering Example – 24x80 Front

 

 

The label “A” on a drawing typically denotes an assembly. 
An assembly can be a single circuit board or a collection of 
components that function together, usually mounted on a single plate or in a single enclosure. 
Assemblies are divided into two types: those that route signal and those that route power.

Module Numbering

 

 
In addition, the following labeling formats might be found on various Daktronics drawings: 
 

· 

“TB_ _” indicates a termination block for power or signal cable. 

· 

“F_ _” signifies a fuse. 

· 

“E_ _” stands for a grounding point. 

· 

“J_ _” represents a power or signal jack.  

· 

“P_ _” symbolizes a power or signal plug for the opposite jack. 

 
Finally, Daktronics part numbers are commonly found on drawings. Those part numbers can be used 
when requesting replacement parts from Daktronics Customer Service. Take note of the following part 
number formats: 
 

· 

“0P-_ _ _ _-_ _ _ _” designates an individual circuit board, such as a line receiver. 

· 

“0A-_ _ _ _-_ _ _ _” indicates an assembly, such as a circuit board and the plate or bracket to 
which it is mounted. A collection of circuit boards working as a single unit may also carry an 
assembly label. 

0P-1195-0001
SN:           6343
05/19/99  REV.1

 

Figure 6: 

Typical Label

 

· 

“W-_ _ _ _” denotes a wire or cable. Cables may also carry the 
assembly numbering format in certain circumstances. This is 
especially true of ribbon cables. 

· 

“F-_ _ _ _” specifies a fuse. 

 
 
 
Most circuit boards and components within this sign carry a label that lists the part number of the unit. 
If a circuit board or assembly is not listed in the replacement parts list in 

Section 4

, use the label to 

order a replacement. A typical label is shown in 

Figure 6 

above. The part number is in bold.
