Reference Drawings:
Components 8/16 Pos Power and Signal Entrance ............................... Drawing A-109114
Components 2/4 Pos Power and Signal Entrance ................................. Drawing A-125977
Route power and signal cables into the scoreboard from the rear. There are two knockouts for conduit
connection in the back. All wires connect to the entrance plate. Drawings A-109114 and A-125977
illustrate the two types of entrance panels.
To gain access to the entrance panel, open the access door or digit panel and remove the cover from the
entrance enclosure. Refer to Section 4 and the component locations drawings for the access location for
your scoreboard.
Connect the power and signal cables to the entrance panel as shown in Drawings A-109114 and
A-125977.
Connections Between Sections
There are several cables in the echo, or slave, sections of the scoreboard that must be connected to
a panel in the master section (refer to Section 4). Route these cables through the 2
1 /
2
" holes in the
mating sides of the various sections when mounting the scoreboard.
To gain access to the entrance panel, open the access door on the front of the scoreboard. Refer to
Section 4 for the location of the access door for the model of your scoreboard.
Pull the cables from the other sections and route them to the bottom of the interconnect panel.
Connect the plugs on the cables to the mating jacks in the interconnect panel. Match the numbers
on the plugs with the numbers on the jacks and insert.
Interconnect Panel Connections
Reference Drawing:
Interconnnect Panel Digit Designation ....................................... Drawing A-174754
All multi-section football and soccer scoreboards use an interconnect panel as a connection
between the digits of the top section and their corresponding driver. Because both drivers are
located in the bottom section, only the top section digits use an interconnect panel. See Figure 5 for
an illustration. For detailed digit designation and the resulting interconnect panel and then driver
designation refer to Drawing A-174754.
