Daktronics AE-3010-7.6-R,G,A - Manual (Page 15)

Introduction
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_ _” represents a termination block for power or signal cable.
• “F_ _” stands for a fuse.
• “E_ _” indicates a grounding point.
• “J_ _” symbolizes a power or signal jack.
• “P_ _” identifies 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 a driver
board.
• “0A-_ _ _ _-_ _ _ _” represents 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-_ _ _ _” shows a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true of ribbon
cables.
• “F-_ _ _ _” indicates a fuse.
Most circuit boards and components within this sign
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 4.7, use the label
to order a replacement. A typical label is shown in
Figure 7. The part number is in bold.
