3.2 Signal Connection
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.

J12 RC-50 Input
Other communication types are initially connected
as shown in the chart: J11 (Radio, RC-100 system)
and J12 (RC-50 receiver). These initial connections
are then routed to the J6 Input jack. Refer to
Drawings A-250728 for a complete listing of driver
connector functions and wiring pin numbers.
Signal Wiring
Signal wires are terminated with a telephone-type RJ14
connector. Route the cable from the jack in the j-box to J6 on the
host driver (Figure 9). Run another RJ14 connector from J8
(Output) to the next (client) display, connecting at J6 (Input).
Follow this sequence to all displays in the sign network.
Figure 9: Driver
Address Dip Switch Settings
Every driver, either host or client, must have a unique address.
The address is set by moving the individual toggle switches in
the eight-position dip switch case located on the driver (Figure
10). The dark area shows that the switch has been pushed down.
In the example, switches 2 and 4 are on.
Figure 10: Dip Switches
Addresses allow the user to set both line number (switches 1-3) and sign number (switches 4-
6) in as many as eight sign groups. All displays with the same line number will show the
same price.
Refer to Drawing B-256001 for an illustration of the client/host driver setups and for a chart
showing line number and sign number settings.
