In addition, various Daktronics drawings may contain the following labeling formats:
•
“TB_ _” shows a termination block for power or signal cable.

“F_ _” denotes a fuse.
•
“E_ _” signifies a grounding point.
•
“J_ _” stands for a power or signal jack.

Finally, drawings commonly have Daktronics part numbers. You can use those part
numbers when requesting replacement parts from Daktronics Customer Service.
Take note of the following part number formats:
•
“0P-_ _ _ _-_ _ _ _” gives the form of an individual circuit board, such as a
module driver.
•
“0A-_ _ _ _-_ _ _ _” represents an assembly, such as a circuit board and the
plate or bracket to which it mounts. A collection of circuit boards working
as a single unit may also carry an assembly label.
•
“W-_ _ _ _” indicates a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true of ribbon
cables.
•
“F-_ _ _ _” signifies a fuse.
Most circuit boards and components within this sign carry a label that lists the part
number of the unit. If the
Replacement Parts List in Section 4.13 does not list a
circuit board or assembly, use the label to order a replacement.
