Introduction 3
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:

‘‘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. (Not all possible formats
are listed here.)

‘‘0P- _ _ _ _- _ _ _ _’’ denotes an individual circuit board, such as a driver
board.

‘‘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 for
ribbon cables.

‘‘F- _ _ _ _ ’’ denotes a fuse.

‘‘T- _ _ _ _ ’’ denotes a transformer.

‘‘PR- _ _ _ _ _ - _’’ denotes a specially ordered part.
