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, flat 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).
