Scoreboard Troubleshooting 19
When troubleshooting driver problems, four red LEDs labeled DS1, DS2, DS5, and DS8 in
provide the following diagnostic information:
LED Function Operation Summary
DS1
Radio/
RS-232 RX Blinking
or off DS1 will be blinking when the driver is receiving radio signal
and off when there is no signal.
DS2 Status Blinking
DS2 will be blinking at one second intervals to indicate the
driver is running.
DS5 Signal RX
Blinking
or off DS5 will be blinking when the driver is receiving current loop
signal and off when there is no signal.
DS8 Power Steady on DS8 will be on and steady to indicate the driver has power.
Note: While it is necessary to have the scoreboard powered on to check the LED driver
status indicators, always disconnect scoreboard power before servicing.
Replacing a Driver
1. Open the digit panel or scoreboard face panel as described in Section 4.2.
2. Remove the metal cover of the driver enclosure to expose the driver components.
3. Disconnect all connectors from the driver by squeezing together the locking tabs and
pulling the connectors free. It may be helpful to label the cables to know which cable
goes to which connector when reattaching the driver.
4. Remove the screws or nuts securing the driver to the inside of the enclosure.
5. Carefully lift the driver from the scoreboard 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 Section 3.7).
9. Close and secure the digit panel, then power up and test the scoreboard to see if
changing the driver has resolved the problem.
4.5 Radio Connections
If a radio receiver needs to be installed, refer to Drawing A-305509. To determine the settings
for radio connections between the scoreboard and control console:
1. Power off any radio-equipped consoles in the area.
2. Cycle power to the scoreboard, and watch for the radio settings. These settings
appear in different locations based on the scoreboard layout, but typically in the first
four digits of a standard lane module.
 When using the All Sport 5000 controller, the scoreboard will display “bX CY”
where X is the Broadcast group number and Y is the Channel number. The
default is b1C1.
Note: If these settings do not appear, the radio receiver may need to be repaired/replaced.
