Testing the Pathfinder System
To test the Pathfinder:
1. Interconnect the system as described in Setting Up the Pathfinder System.
2. Place the Pathfinder transducer in water (at least a few inches to cover the transducer face).
3. Apply power to the system.
4. Start the TRDI Toolz program (for help on using TRDI Toolz, see the TRDI Toolz Help file).
5. Click the Break button. The wakeup banner appears on the log file window.

6. At the “>” prompt in the communication window, enter the command CR1 then press the Enter
key. This will set the Pathfinder to the factory default settings.
7. At the “>” prompt in the communication window, enter the command CK then press the Enter
key. This will save the factory default setting.
8. At the “>” prompt in the communication window, enter the command PS0 then press the Enter
key. This will display the Pathfinder system configuration data.

9. At the “>” prompt in the communication window, enter the command PA then press the Enter
key. This will run the Pathfinder Pre-Deployment test.
Submerge the transducer face in a few inches of water. The PA test may fail in air. Only a
failure with the transducer in water is a relevant test.
This test may fail if the Pathfinder is exposed to electrical interference such as that from
other acoustic devices or SONARs or other electronic devices (i.e. cellphones, radios,
computers, TV’s, etc.). The test may also fail if the Pathfinder or its cable is exposed or
installed near potential sources of EMI’s such as high voltage lines like main engine cables,
galley equipment, winches, engine room equipment, cranes, high voltage lighting circuit, etc.
Interference from the mentioned sources may contaminate the Pathfinder’s data as well.
Oftentimes, a noisy (i.e. non-UPS) power supply may cause failures in this test as well.
