Only a qualified individual should terminate power and signal cable within this
Daktronics display.
The Daktronics engineering staff must approve any changes made to the display. Before
altering the display, submit detailed drawings for the proposed modifications to the
Daktronics engineering staff for evaluation and approval or the warranty will be rendered null
and void.
3.1 Common Connectors in the Display
The power and signal connections in the displays use many different types of
connectors. Take special care when disengaging any connector so as not to damage
the connector, the cable, or the circuit board.
When pulling a connector plug from a jack, do not pull on the wire or cable; pull on
the jack itself. Pulling on the wires may damage the connector.
The following information presents some common connectors
encountered during display installation and maintenance.
Figure 9: Ribbon
Cable Connector
1. Ribbon Cable Connectors:
Figure 9 illustrates a typical ribbon connector. To disconnect the
ribbon cable, push the plastic clips on the sides of the jack to
unlock and remove the cable.
Before replacing a ribbon cable connector, spray it with DeoxIT
™
contact cleaner to remove any foreign matter that may cause
signal problems. In addition, apply a generous amount of
CaiLube
™ protector paste to the plug before inserting it into the
jack. This paste will protect both the plug and the jack from
corrosion.
Figure 10: Termination
Block
2. Termination Blocks:
Termination blocks are usually used to connect internal power
and signal wires to wires of the same type coming into the
display from an external source. Power wires need to have one-
half inch of insulation stripped from the end of the wire prior to
termination. Tighten all screws firmly to ensure a good
electrical connection. Refer to
Figure 10 .
