Installing an RJ Connector
Installing an RJ connector on the end of the conductor cable is a
simple task when the correct tools are used. The RJ crimping tool
(Daktronics part number TH-1033) performs two separate steps.
First, use the crimping tool to strip the outer insulation from the inner
wires. This does not result in bare wires since only the gray outer
jacket is removed. After correct stripping, the wire will appear as
shown in
Figure 15 on the right.
The crimping tool is then used to crimp the RJ connector onto the cable. The RJ connector is locked
into a special socket in the tool. The stripped wire is inserted into the RJ connector. Finally, the tool is
squeezed like a pliers to crimp the connector onto the wire. This completes the installation of an RJ
connector onto
the wire.

Daktronics does not include the conduit. Refer to the appropriate shop drawing for your display size
located in
Appendix B for approximate locations for power and signal conduit. Separate conduit must
be used to route:

Power

Signal IN wires

Signal OUT wires (if signal is required for another display)
Knockout holes for ½" conduit are located at the bottom right (rear view) of the back of the display
(refer to
Shop Drawings located in Appendix B ).
For displays with more than one face, signal and temperature sensor wiring between displays can be
routed through the same conduit.
3.5 Preparing for Power/Signal Connection
1. Punch or use 7/8" (0.875) holes for the desired ½" conduit openings. Be careful that none of
the internal components are damaged . Attach the conduit.
2. Remove the bottom left two modules (AX01 and AX02) to expose the power enclosure and
signal panel. To do this, use a nut driver or

one-quarter turn. Turn the top latch clockwise and the bottom latch counter-clockwise. Lift
each module away from the display; reach behind it and disconnect all power and signal
connections.
3. Locate the controller and power termination box for these displays in the Component Layout
Diagram .
4. The controller receives the incoming signal and relays it to the individual modules.
5. Route power to the display through a fused disconnect switch capable of opening all
ungrounded power conductors. Install this disconnect within the line of sight of any personnel
