Junction Boxes and Data Cable
If your scoreboard package includes the ScoreLink wireless communication system,
your work is done here. Skip to the next section.
The following material assumes the use of a single run of cable to send data to all four
faces of a center-hung scoreboard. It is possible to treat each face independently, but
this material sticks to the basics. Let your
scoreboard sales rep know if you have
special requirements.
Your hard-wired scoreboard package
includes a junction box, which you should
permanently mount to provide a stable point
of termination for the data cable. The idea is
to connect the control console to this junction
box via a ten-foot patch cable. So the
junction box will need to be mounted within
ten feet of the position where your
scoreboard operator will sit. In many gyms
the junction box is concealed inside a larger floor box. The box can be flush mounted
on a wall, externally mounted on bleachers, or positioned anywhere else that is
convenient. Choose a location that is protected so that the junction box and cables are
not likely to be stepped on, tripped over, or have liquid (or anything else) spilled on
them.
It is also important to label your junction box. The connectors used for scoreboard data
look very much like the type used in some audio systems. Plugging audio devices into
a scoreboard data line can often damage the scoreboard.
The junction box ships with a length of cable
soldered to the stereo socket and tucked
inside the box. There should be no need to
solder cable to this socket during the
installation. Instead, splice the wires from the
cable to the pigtail inside the junction box,
matching colors. The wires in the pigtail are
22 AWG, and the cable should use the same
size conductors. The installer must provide
wire nuts, crimp splices, or other means to
connect the wires.
The splice point should stay inside the
junction box. That is, you want to feed the long run of cable into the box rather than
pulling the pigtail out. Electro-Mech provides a strain relief on one side of the junction
box to secure the cable. You may choose to connect conduit directly to the junction
