Overview
The Pathfinder transducer assembly contains the connectors with connector protective cap s, housing,
transducer ceramics, and electronics. The standard acoustic frequency is 600 kHz. See the Outline Instal-
lation Drawings for dimensions and weights.
The urethane face covers the transducer ceramics and provides a robust, flexible waterproof
seal. Avoid setting the transducer on bumpy surfaces that may leave an indentation in the
urethane or damage the urethane face, anodized finish, or paint.
The Pathfinder housing contains Electrostatic Sensitive Devices. Take accepted ESD
prevention measures before removing the housing.
The PWR/COMM cable connects the Pathfinder to the computer and external power supply.
When the cable is not connected, use the connector protective cap to protect the connector.

Inventory
The following DVL Kits are available:
•DVL Standalone: This provides you an option to purchase the DVL with only the necessary parts
to install it in your vehicle. This is especially adapted, once the first integration has been com-
pleted and therefore test cables and other accessories are no longer needed.
•DVL Development Package: The DVL Development Package is a complete package to integrate,
evaluate and use your PathFinder DVL. The DVL Development Package was designed to help you
start testing, configuring and integrating your new devices quickly.
•DVL Integration Kit:The DVL Integration Kit has been designed to save you both time and money
by speeding up the evaluation and the integration of our products into your vehicle.
•Field Service Kit: The Field Service kit has been designed to allow you to service, repair, and test
your DVL with the assumption that you do not have any kits already available.

Health & Environment Monitoring Sensors
Health and Environment Monitoring (HEM) Sensors monitor the health of the Pathfinder system.
•Leak Detection – Water leaking into a Pathfinder DVL can not only potentially destroy the DVL,
but also cause severe issues for the host vehicle that is carrying the DVL, such as loss of naviga-
tion ability. The Pathfinder detects water leaking into the system and reports it in the PD0, PD4,
PD5, and PD6 messages. The Pathfinder also supports the PC4 and PC5 user interactive test for
reporting the status of the leak sensors. There are two leak sensors; One is mounted at the back
of the transducer head and the other at the bottom of the electronic section (Leak Sensor B is
only available on the ROV Self-Contained version).
•Transducer Monitor – The Pathfinder monitors the transmit voltage and current of the transducer
and reports Transducer Impedance as a result. This information provides insight, in near real-
time, to the status of the transducer and alerts the user should problems arise. This data is re-
layed back to the user in the PD0 Bytes 76 and 77 and PD6 output data structure.
•Operating Time – The Pathfinder system records the total time of operation in minutes where
“operation” is defined as the time that the system ping loop is active (CS command has been
sent). The record of the total awake time has a maximum value of 33,554,432 minutes, which
corresponds to over 500,000 hours of operation. The value of the counter can be read as part of
the PS5 command. Although the time is stored in minutes, the operating time is reported in
hours with one decimal place.
Example PS5 output:

Operating time: 4327.5 hours
