Daktronics FB-2006 Generation III Stackable LED Scoreboard - Manual (Page 33)

Maintenance and Troubleshooting 27
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. Refer to Drawing A-115078 for a listing of the
wire/pin connections for driver addresses 1 – 128.
Replacing a Driver
Drivers are typically mounted inside the scoreboard and immediately behind a digit,
but location and mounting varies with the model of the scoreboard. Refer to the
component locations drawings at the beginning of this section for the location of
your scoreboard driver. All scoreboards in this manual are front-accessible.
Each driver is enclosed with a power supply and signal terminal block. Before a
failed driver can be reached, the enclosure must be accessed.
Follow the steps below to remove a driver.
1. Open the digit panel or scoreboard face panel as described in Section 5.2.
2. Remove the cover from the driver enclosure.
3. Disconnect all connectors from the driver. Release each connector by
squeezing together the locking tabs as you pull the connector free.

Note: When reconnecting, remember that these are keyed connectors
and will attach in one way only. Do not attempt to force the connections.
4. Remove the screws, nuts, or wing nuts securing the driver to the inside of
the enclosure. Refer to Figure 5.
5. Carefully lift the driver from the display and place it on a clean, flat surface.
