WHS 3000 Series
Wireless Hydrophone System

A Family of MAP-Coded Submersible Acoustic
Receivers / Dataloggers
and RF Wireless Options

Lotek WHS 3000 Series products represent a set of modularized underwater datalogging hydrophones and surface communication components that can be combined in various ways to create completely autonomous and/or remotely accessible solutions for acoustic fish transmitter monitoring and position tracking.

Each system is based on Lotek field proven MAP (CDMA) coding technology and designed to exceed the limits of conventional acoustic aquatic animal tracking and monitoring. This includes identification of multiple individuals in acoustically high noise / high multipath environments while providing an efficient transmission channel for sensor tag data, such as an animal's activity, depth and/or temperature.

• Unattended, self contained underwater data logging of Lotek MAP coded acoustic tags – support for 76 or 200 kHz frequency
• Compatible and complementary with field proven mobile surface tracking Lotek receivers such as the MAP 600 RT.
• Lotek MAP system feature support for tracking hundreds of active transmitters with high broadcast rates at the same time and location.
• System feature support for the discrimination of thousands of individual ID’s on a single acoustic frequency.
• High signal discernability and reliability in acoustically noisy environments.
• Transmission of physiological / environmental data, e.g., motion, pressure and/or temperature, from multiple transmitters occupying the same spatial and temporal coverage area.
• User defined operating scheduler for optimized data collection and longevity
• Small size and weight of WHS 3050 allows handling by one person during deployment and retrieval
• Wet mateable plug for data access, configuration and control
• IEEE RS422 interface for extended cable line data transfers of 100+ meters
• User upgradeable operating system firmware
• Standalone visual pulsed light feedback of active tag detections

Each WHS 3000 Series datalogger consists of the following components:

HARDWARE

• WHS 3050/3150 acoustic MAP data logger with integrated hydrophone
• RS-422 Serial communication cable (requires USB to RS-422 converter for use with conventional PC I/O hardware)
• User upgradeable 256 M Byte internal SD flash data protection
• User replaceable alkaline battery pack
• Heavy duty mooring bracket with attachment hardware
• User manual

SOFTWARE

MapHost (ver. 4.0 or higher)
User access to WHS 3050/3150 functions is provided through MapHost software via a standard serial interface (USB recommended).

MapHost is a Windows^® 95/98/ME/NT/2000/XP compatible software application which has been designed to provide PC interface support (system configuration and operation) to users of the WHS 3050/3150 MAP datalogger acoustic coded receiver. It includes serial communication services, configuration file management, streamed data capture and an interactive virtual control panel (VCP).

Active datalogging and sleep periods are set by the MapHost Scheduler to optimize system memory and available battery power.

BioMAP
Data processing tools, database management and graphical display services for data are provided by BioMAP software.

BioMAP is a comprehensive software environment for processing and managing data from acoustic or radio telemetry studies of animal behavior and/or ecology. While ultimately providing a framework for the handling of data from a number of instrument platforms, BioMAP has been configured to permit the efficient storing of data generated by Lotek's MAP acoustic receiver family. Stored data may then be classified, filtered and viewed using any one of a range of optional database tools available within BioMAP. The data structures employed by BioMAP are hierarchically ordered. This permits the concurrent use of multiple databases, each supporting multiple data sets and permitting unique processing strategies.

Additional BioMAP Features
BioMAP offers extensive data management tools to enable a user to:

• Organize logged data collected by the receiver
• Provide management of information concerning animals, tags and the environments
• Allow the database to be queried with different levels of sophistication using SQL scripts (optional)
• Provide interface to third party utilities such as GIS and other computational packages

¹ BioMAP software module(s) supplied will depend upon MAP 600 system architecture selected to meet application requirements.

• Direct connect data transfer via RS422 cable & option for underwater to surface access
• Flash memory backup (Lotek service accessible)
