1.2 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 useful when
trying to communicate maintenance or troubleshooting efforts.
The label “A” on a drawing item 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.
In addition, the following labeling formats might be found on various Daktronics drawings:
ƒ
“TB _ _” denotes a termination block for power or signal cable.
ƒ “F _ _” denotes a fuse.
ƒ “E _ _” denotes a grounding point.
ƒ “J _ _” denotes a power or signal jack.
ƒ “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 Call Center. Take
note of the following part number formats. (Not all possible formats are listed here).
ƒ
“0P- _ _ _ _- _ _ _ _” denotes an individual circuit board, such as a driver board.
ƒ “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.
ƒ “W- _ _ _ _ ” denotes a wire or cable. Cables may also carry the assembly numbering
format in certain circumstances. This is especially true for ribbon cables.
ƒ “F- _ _ _ _ ” denotes a fuse.
ƒ “T- _ _ _ _ ” denotes a transformer.
ƒ “PR- _ _ _ _ _ - _” denotes a specially ordered part.
ƒ “M- _ _ _ ” denotes a metal part, and “0M-_ _ _ _ _ _” typically denotes a fabricated
metal assembly.
