Protective Coating Inspection
For more protection, the case and the transducer assembly are first anodized per MIL-A-8625, Type III,
Class 2, Nickel Acetate Seal. Do not damage the surface coatings when handling the Pathfinder.
Inspect the housing, and transducer assemblies for corrosion, scratches, cracks, abrasions, exposed metal
(silver-colored aluminum). Be critical in your judgment; the useful life of the Pathfinder depends on it.
If there is any damage to the anodizing near the edges of the urethane transducer face or the
connectors, DO NOT DEPLOY THE PATHFINDER. Please contact TRDI Support Team for advice.
Long Term Maintenance Items
The O-Rings and desiccant should be replaced every two years. Firmware updates may be done when
needed.
Before opening the system, order the 757BK6087-00 Kit, Field Service, ROV Pathfinder or
757BK6089-00 Kit, Field Service, OEM Pathfinder. These maintenance kits includes all of the
hardware, O-rings, and desiccant required to seal the system.
Instructions on how to open and close the housing are included with the ROV field service kit.
Updating the DVL Firmware
To update the Pathfinder DVL firmware:
1. Connect the serial cable and apply power as described in Connecting to the Pathfinder.
2. Run the Pathfinder_XX-xx.exe file, where XX-xx is the firmware version. This is a self-extracting
zip file that contains all the files needed for the firmware upload. You can specify a location to
where the files will be extracted. If no location is specified, the files will be extracted to the current
folder.
3. The default serial-port in the firmware download batch file is COM1. If the Pathfinder is con-
nected to another serial-port, edit the Pathfinder.bat file. Open Pathfinder.bat file with Notepad
®
and change the setting to the serial port number; e.g. to 6 if the Pathfinder is connected to COM6.
Save the file, and then close.
4. Double-click on the Pathfinder.bat file. This will start the firmware upload process.
