Platform sonar controller.

This controller is plugged into the Sonar 1 connector on the Lynx core. This con-
nector is not accessible from the payload bay, but does not need to be unplugged
for this procedure.

The controller will be at the very front of the payload bay, screwed into the pay-
load bay deck with two screws.
a. Unscrew the controller from the payload bay deck by removing two screws.
Retain the screws for mounting the replacement controller.
b. Unplug the larger cable from the sonar controller.
Be careful not to let the cable end slip into the chassis.
c. Unplug the eight sonar unit cables from the controller.
These are the smaller cables that go to the individual sonar units.
Make sure these are labeled and tied up, so they can't slip into the chassis.
d. Remove the controller from the payload bay, and replace it with the new one.
e. Connect the eight sonar unit cables to the new controller.
Ensure that the cable labels match the controller labels.
f. Plug the larger cable into the new controller.
g. Screw the new controller to the payload bay deck, using the two screws removed
from the old controller.
3. Reinstall the payload structure.
4. Dispose of the old controller according to local and national regulations concerning elec-
tronic components.
Light Discs
The two light disc assemblies and their controllers are single units, so replacing a controller
also replaces all of the lights on that side of the platform.
1. Remove the side cover, on the side that needs the light disc assembly replaced.
Refer to Removing and Installing Covers on page 93.
2. Unscrew the four screws holding the light disc PCA to the side cover.
Retain the screws and round cover for installing the new assembly.
3. Remove the light disc PCA.
4. Screw the new assembly and retained round cover to the side cover, using the screws
retained from the old assembly. The PCA is keyed so that it can only be installed in one
orientation.
5. Reinstall the side cover, connecting the cable to the new light disc PCA.
