junction box, in which case the strain relief will not be needed. The junction box is
designed to accept 3/4-inch conduit fittings.
We recommend running data cable in conduit from the junction boxes to the shot clock
displays
─
especially where the cable would otherwise be exposed. You should never
run data cable in the same conduit as power cable. Having more than one run of
scoreboard data cable in a single conduit is perfectly fine.
One more warning about data cable: Never split or branch the cable. The current loop
signal we use to transmit data to the scoreboard and shot clock displays will behave
unpredictably if it is divided between two destinations. There are other options for
getting synchronized data to two locations, including daisy chaining
─
which will be
discussed below. If your facility calls for a more complicated cabling plan, it is best to
work out the details with your scoreboard sales rep prior to installation.
Stereo Plug
At each shot clock display, data enters the cabinet through a port located along the top.
The illustration below is a view of the top of the cabinet showing the standard location of
the ports.
There are two common methods for bringing the last few feet of data cable to one of the
shot clock displays. One method involves installing a junction box on the wall or other
structure near the display. From here you can run a patch cable to the shot clock's data
input port. The standard scoreboard package does not include extra junction boxes and
patch cables for this type of cable routing.
However, the materials are readily available
from Electro-Mech.
The other method uses the right-angle stereo
plug assembly, which is provided with all hard-
wired indoor scoreboard packages. In the case
of shot clocks, there will be two plug assemblies
to terminate the two cable runs required. The
assembly consists of the main plug body, an
insulating sleeve, and a cover.
