Introduction 1-8
Signal Converter: The signal converter is a Daktronics supplied unit that converts the data from
RS232 to RS422. The signal converter is used in RS422 systems.
TCP/IP: The TCP/IP (Transmission Control Protocol/Internet Protocol) is a communications protocol
used for LANs.
TX LED: A TX LED is a LED on the serial converter that indicates the control PC is sending data to
the display.
Venus 1500: The Venus 1500 is a Daktronics designed, Windows-based software used to run the
displays.
1.6 Daktronics Nomenclature
To fully understand some Daktronics drawings, such as schematics, it is necessary to know how
various components are labeled in those drawings. You will find this information useful when trying to
communicate maintenance or troubleshooting efforts.
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??” 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.
• “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.
• “F-????” denotes a fuse.
• “T-????” denotes a transformer
• “PR-?????-?” denotes a specially ordered part.
