5. Carefully lift the driver from the display and place it on a clean, flat surface.
6. Position a new driver over the screws and tighten the nuts.
7. Reconnect all power/signal connectors.
Note: The connectors are keyed and will attach in one way only. Do not attempt to
force the connections.
8. Ensure the driver is set to the correct address (refer to Setting the Driver Address).
9. Close and secure the digit panel, then power up and test the scoreboard to see if
changing the driver has resolved the problem.
Setting the Driver Address
Since the same LED drivers can be used for many scoreboard models, each driver must be set
to receive the correct signal input, or address, for the model being used. Addresses are set
through the S1 dip switch on the driver (Figure 24) using a pen or small, pointed object.
Refer to the specifications table in Section 2 to determine the correct address setting of the
driver(s) in a particular scoreboard model and see Drawing A-290261 in Appendix A for
addressing information for driver addresses 1 – 128.
Another method of setting the driver address using the J19 address plug is available. 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.
When using an address plug, it will not be possible to set the address with the S1 dip switch.
Multiple Drivers
Scoreboards with multiple drivers operate using a master/slave driver configuration. If it
appears as though only a certain group of digits on the scoreboard is not functioning, there
may be a problem with the slave driver(s) or the power/signal connection from the other
driver(s). Refer to Section 4.5 for more information about these connections.
5.8 Power Supplies
Scoreboards with 16-column driver enclosures require a dual 150 W power supply assembly.
All scoreboards with white digits (except FB-3010, MS-2918, & SO-2011) will also have at least
one 1000 W power supply in addition to, or in place of, the power supplies in the driver
enclosure. The 1000 W power supplies are located in a separate enclosure. If a certain group of
digits is not lighting up, the power supply they are all connected to may need to be replaced.
