Nomenclature 

 

 

 

Figure 5: Numbering Example - 24x80 Front 

 

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. 
 
A module is the building block of the 
Galaxy

®

 display. Each module measures 8 

pixels high by 16 pixels wide. By placing 
modules side-by-side and on top of one 
another, a display of any size can be 
designed and built. Individual modules can 
be easily removed from the display if 
required

Figure 5

 

above illustrates how 

Daktronics numbers modules on a Galaxy

®

 

display. 

Figure 6

 on the right

 

demonstrates 

the module numbering method. 

 

 

Figure 6: Module Numbering 

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

• 

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

• 

“F_ _” denotes a fuse. 

• 

“E_ _” signifies a grounding point. 

• 

“J_ _” indicates a power or signal jack.  

• 

“P_ _” identifies 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-_ _ _ _-_ _ _ _” shows an individual circuit 
board, such as the internal fiberboard. 

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

 

 

Figure 7: Typical Label 

• 

“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.
