Scoreboard Troubleshooting 27
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 19 ) 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.
5.6 Radio Connections
To determine the settings for radio connections between the scoreboard and control console:
1. Cycle power to the scoreboard.
2. After approximately seven seconds, the radio settings will be displayed. The first
values are the broadcast settings (“b1”), and the second are the channel settings
(“C1”). These values must match the settings within the console.
Note: If these settings do not appear, the radio receiver(s) may need to be
repaired/replaced.
To make sure the current radio settings match the receiver in the scoreboard, refer to the
operation manual of the particular control console being used (see
Section 1.4 ).
