Introduction
1.1
System Overview
The VR2AR / VR2AR-X (Receiver, Transmitter, and Acoustic Release) is a submersible,
single-channel acoustic receiver capable of transmitting its assigned ID code, identifying
other VEMCO coded transmitters in the area, acoustically communicating with a VR100-
200 receiver, and separating from its mooring after an acoustic command. The receiver
operates on a factory set frequency of 69 kHz.
The VR2AR is housed in a corrosion resistant cylindrical plastic high pressure case. The case
incorporates an integral hydrophone at one end of the case and a replaceable mooring lug at
the other end. The VR2AR has the ability to:
Detect VEMCO 69kHz coded tags
Store detections and events within internal memory
Transmit an ID code at a user chosen rate (select transmitting options to choose from)
Communicate with VUE software through a Bluetooth connection
Quickly and reliably release from its mooring lug (typically within one minute)
Easily re-arm the release mechanism
Allow easy attachment of floatation to exterior casing for buoyancy
Respond to a VR100-200 without entering a specific serial number or location
Communicate additional status information to the VR100-200 and make changes to select receiver and
transmitter operations while deployed, such as power settings
Report release status, arm the release, and activate the release through the VR100-200 acoustic
communication
Report range and depth information as the unit is rising to the surface
The VR2AR communicates to the surface through our VR100-200 active tracking receiver. It is compatible
with all VR100-200 models sold since January 2013. Customers will require a new transponding hydrophone
to attach to the VR100 to communicate with either the VR2AR or the VR2Tx. VR2AR
receiver information that can be accessed through the VR100-200 includes:
Unit health
Number of detections
Programmable watch table
Tilt, depth and temperature
Battery life and memory usage
Receiver range which will aid in locating the VR2AR
Built in Transmitter configuration allowing users to change the power setting as
well as enable and disable the transmitter
The release mechanism is a mooring lug that is controlled by a DC motor using a titanium shaft.
The exterior of the mooring lug shaft is copper to reduce bio-fouling.
Some common uses for VR2AR receivers are:
•
Monitoring fish movements using acoustic gates across shorelines
•
VEMCO Positioning System (VPS) arrays to track animals within a specific area
