In the scoreboard, the LED drivers perform the task of switching digits on and off.
Refer to
Drawing A-178197 . Each driver has up to 19 connectors providing power
and signal inputs to the circuit and outputs to the digits and indicators. The
connectors function as follows:
16-Column LED Driver
Connector No. Function
1 – 16 Output to digits and indicators
17 Power and signal input
18 Relay
19 Address
20 Protocol
Output connectors 1 through 16 each have nine pins. Pin 7 provides power (hot) to
the digit or indicators wired to that connector. The other eight pins provide switching
connections.
For the scoreboard to receive signal and function properly, the driver must be set to
the correct address. This address is set with jumper wires in a 12-pin plug which
mates with a jack on the driver.
Drawing A-134371 details the specifications for 16-
column drivers. Refer to Drawing A-115078 for a listing of the wire/pin connections
for driver addresses 1 – 128.
