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
1-8
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.
above illustrates how Daktronics numbers modules on a
Galaxy
®
display.
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
. The part number is in
bold.
