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.

Figure 2: Module Numbering Example -- KE-1010-16240-2.1 Shown

A module is the building block of the display. Each module measures either 16 or 24

pixels high by 40 pixels wide. By placing modules side-by-side, a display of any

length can be designed and built. Individual modules can be easily removed from the

display if required

. Figure 2 illustrates how Daktronics numbers modules on a

DAKTicker display.

Figure 3 breaks

down the module numbering method.

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.

In addition, the following labeling

formats might be found on various

Daktronics drawings:

• “TB??” denotes a termination block for power or signal cable.

• “F??” denotes a fuse.

• “E??” denotes a grounding point.

• “J??” denotes a power or signal jack.

• “P??” denotes 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

shift card.

• “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.

• “W-_ _ _ _” represents a wire or cable. Cables may also carry the assembly

numbering format in certain circumstances. This is especially true of ribbon

cables.
