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.
Since this shot clock set consists of two separate displays, hardwired systems require
two separate runs of data cable from the point of operation of the signs
─
one to each
display. In many cases, a third run of cable
will send the signal to the main scoreboard
display. Your hard-wired shot clock package
includes two junction boxes, which you
should permanently mount to provide a stable
point of termination for the data cables. The
idea is to connect the control console to
these junction boxes via a pair of patch
cables
─
typically 10-foot long patch cables
shipped with your shot clocks. So the
junction boxes will need to be mounted within
ten feet of the position where your
scoreboard operator will sit. In many gyms
the junction boxes are concealed inside a larger floor box. They 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 boxes 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 boxes. 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 damage the scoreboard system.
Each 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
data 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 data 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
