Introduction 5
1.6 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.
A module is the building block of the Galaxy display. Each
module measures 8 pixels high by 8 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 3 above illustrates how Daktronics
numbers modules on a Galaxy display. Figure 4 on the
right breaks down the module numbering method.
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-_ _ _ _-_ _ _ _” denotes an individual circuit board, such as the internal fiberboard.

“0A-_ _ _ _-_ _ _ _” denotes 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-_ _ _ _” denotes 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 display 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 5 below. The part number
is in bold.
