3.2 Signal Connection
To connect signal, it is necessary to access the driver inside the display cabinet. The driver is
attached to a small panel between the left and center digits (
). Open the small panel
by turning the latch access fasteners counterclockwise.

LED Drivers
In the display, the LED driver performs the task of
switching digits on and off. One driver at each sign
installation is designated as the “host driver.” This
driver receives its signal directly from the controller
on the Signal In connector J6. The Signal Out
connector J8 is used to connect to “client drivers,”
the drivers in other displays in this network.
