Multiple Driver Connections
Some models in the single-section outdoor scoreboard line require multiple drivers, and
those models are configured to operate with a master/slave driver system. Master and slave
drivers function identically, but slave units lack the power termination block and signal
surge suppression card. The two drivers have been designed to simply plug into one another
via an interconnect harness, the slave receiving power and redriven signal from the master
driver enclosure. Larger boards can add as many driver slaves as they require.
All driver interconnect harnesses are factory-installed. No additional connection is necessary.
(The harness emerges from the bottom of the master driver enclosure, and the J42 jack from
the master is connected to the slave’s P43 plug.) Likewise, signal cables from drivers to digits
have also been factory-installed and no additional connection is necessary.
Refer to the scoreboard drawings to determine driver location and other model-specific
information not listed in this manual.
