Replacing a Driver
If the driver status indicators do not appear to be working correctly, it may be necessary
to replace the driver.
1� Open the control enclosure by removing the 6 screws and swinging the door open.
2� Disconnect all plugs from the driver by squeezing together the locking tabs and
pulling the connectors free. It may be helpful to label the cables or take a picture to
know which plug goes to which jack when connecting the replacement driver.
3� Remove the 4 nuts securing the driver to the control enclosure door.
4� Carefully lift the driver from the enclosure and place it on a clean, at surface.
5� Position a new driver over the screws and tighten the nuts.
6� Reconnect all plugs to their mating jacks on the driver. The connectors are keyed
and will attach in one way only. Do not force the connections.
7� Ensure the new driver is set to the correct address and switch settings. This will be the
same as the old driver being replaced. Refer to Setting the Driver Address (p�10)
and Switch Settings (p�10).
8� Close and secure the enclosure door, then power up and test the display to verify the
issue has been resolved.
Setting the Driver Address
Since the same LED drivers can be used for many display
models, each driver must be set to receive the correct signal
input, or address, for the model in which it is being used.
This address is set with jumper wires in a 12-pin plug which mates
with jack J1 on the driver. Refer to Figure 5. After replacing the
driver in the control enclosure, be sure to use an Address 1 plug
in jack J1. In most cases, the same plug can be reused from the
driver that was replaced; otherwise, one may be ordered from
Daktronics (part # 0A-1150-0122).
