1 Introduction

1.1 System Overview

The VR2W is a submersible, single-channel acoustic receiver capable of identifying VEMCO
coded transmitters. The receiver operates on a factory set frequency of either 69 kHz or 180
kHz. VR2W receivers can decode uniquely coded pingers and sensor transmitters that operate
on the same frequency as the VR2W.

The VR2W is housed in a corrosion resistant cylindrical plastic high pressure case, an d
incorporates an integral hydrophone at the tapered end of the case. The VR2W features include
Bluetooth® wireless technology, a Smart LED, 16 megabytes of data storage, record mode, and
a replaceable battery (single Lithium cell).

The VR2W records the tag code number, the date/time of valid detections, and sensor data if the
tag received is equipped with a sensor. This information is stored in the VR2W memory until it
is downloaded from the receiver using Bluetooth wireless communication and a PC running
VUE software.

Some common uses for VR2W receivers are:

• Monitoring fish movements using acoustic gates across shorelines

• VEMCO Positioning System (VPS ) arrays to trac k animals within a specific area

Visible External Differences:

1.2 VR2W Case

The VR2W receiver is housed in the black plastic high pressure case. The case consists of an outer cylinder
that is removed to install the D-cell Lithium battery, and the endcap which houses the hydrophone and
connects to the plastic internal casing. When the outer cylinder is removed, the internal casing protecting the
electronics can be seen. There are two types of internal casing, the older metal/PVC casing and the current
plastic casing. This manual focuses on the current case type; instructions for the older case are found in the
appendix (section 9.1).

A crucial part of the VR2W is the hydrophone, located at the top of the receiver. The hydrophone is similar
to a microphone – it “listens” for sounds and transfers them to the electronics inside the receiver. Be very
careful not to bump the hydrophone or damage may occur that may prevent the receiver from detect ing tags.

The VR2W is only capable of listening to one frequency so that frequency must be selected at the time of
ordering. The frequency chosen is based on the coded tags that will be used and can be either 69 kHz or 180
kHz. The frequency is reflected in the name of the r eceiver, the VR2W-69kHz or the VR2W-180kHz.

Externally there are physical differences between the VR2W-69kHz and the VR2W-180kHz which make it
easier to identify the operating frequency at a glance. The VR2W-180kHz has a smaller hydrophone than the
VR2W-69kHz, and the identification band around the middle of the VR2W-180kHz receiver has green text
while the VR2W-69kHz has blue text. The dimensions of the two cases are slightly different – diag rams are
found in section 6.5.

The cases operate in the same manor so they’ll be
described simply as a VR2W in this manual.

2 Getting Started

Before the VR2W can begin recording detections, it must be powered. VR2W receivers are either shipped
with the D-cell Lithium battery inside the case but not connected to the receiver, or with no battery inside the
case. In either case, the VR2W case must be opened to power the receiver.

2.1 Open the VR2W Case

Two steel rods are necessary to properly open and close the VR2W case. Every shipment of new VR2W
receivers includes a pair of steel rods.

The procedure for opening a VR2W case is th e same
regardless of the operating frequency of the receiver.

om the rope before opening the case.

This also means the electronics cannot be exposed to a sudden change
in temperature and humidity that will cause condensation to develop on
the electronics and destroy the receiver.

It is vitally important that the electronics insi de the receiver case do not come in contact
with any water or the receiver will be damaged. For this reason, VEMCO recommends the
VR2W be opened in a controlled environment and not in the field or on the deck of a boat.

2.3 Close the VR2W Case

Before deploying or storing a VR2W receiver, the case
must be properly closed and sealed to prevent damage to
the electronics. Even humidity in the air can, over time,
cause damage to the electronics so it’s very important to
keep the case sealed, with a functioning desiccant pack
inside, as much as possible. Important information about storing a VR2W is found in section 5.3.

2.4 Testing

Before deploying a VR2W, it is wise to test it with a tag to verify that it is
operating properly. This test also creates a VRL file containing all the
configuration information for this receiver – handy to keep as a record of
the receiver’s configuration.

Tests can, and should, be done in both air and water.

2.4.1 In-Air Test

The VR2W can detect coded pingers in air, but at a much reduced range compared to their r ange capabilities
in water. Perform air tests away from electrical noise sources such as motors, PC screens, or fluorescent
lights.

To perform an in-air test, follow the steps below.

1. Activate the Bluetooth feature on the VR2W (section 3.2

2. Establish communication between the VR2W and VUE software (section 3.3).

3. Begin a Study. Section 3.4.1 has the details of how to begin a study, also known as initializing a

receiver.

4. Disconnect the wireless communication with the VR2W (click the red box with

the “X” in the receiver ribbon

5. Activate a tag that operates on the same fr equency that the VR2W operates and

place it near the hydrophone. For 69 kHz equipment, place the tag less than 30
cm (12”) away from the VR2W-69kHz hydrophone; for 180 kHz, place the tags
less than 8 cm (3”) from the VR2W-180kHz hydrophone. Position the tag so the
side of the tag is facing the side of the VR2W hydrophone.

6. Wait while the VR2W records the tag(s) near it. You can watch the flash patterns

as the tag is detected and the data is stored in memory. Each faint flash of the
Status Light (LED) is a received ping and a long, bring flash is a stored detection.
If the flash patterns are different, compare i t to the Status Light Meanings
(section 6.2).

7. Communicate

number of detections and pings received listed in the receiver status information.

8. Offload the data that was collected dur ing the test (section 3.5), creating a VRL file.

9. View the data to verify that the data was stored and retrieved without problems. Instructions for

viewing data are found in the VUE manual.

chart

Tests performed in water are almost iden tical to the in-air test explained above. The only difference is that
the tags should be positioned farther from the receivers – 5 meters is suggested. In-water tests are often
performed to establish an ideal range for the VR2W receivers in the environment in which they are moored.

3 Communication

The VR2W uses Bluetooth communication between the receiver and the VUE software. This feature
dramatically increases data offload speed compared to the cabled communication of the retired VR2 receiver.
For example, to offload 2 MB of data requires 3.3 minutes for the VR2W to accomplish but it would have
taken the VR2 more than 75 minutes. A comparison table is located in section 6.1.2 for more information.

Bluetooth is still a relatively new standard and we have observed that not all
Bluetooth devices are created equally or work reliably. To ensure successful

operation with the VEMCO VR2W, we provide our users with a Bluetooth
USB adapter in the VR2W Communications Package that we are confident
will provide reliable functionality.

3.1 Install VUE software

VUE software is used to communicate with the VR2W family of receivers, allowing studies to be setup and
data to be offloaded. The software requires Windows XP SP2, Windows VISTA, Windows 7, or W indows 8.

The Bluetooth USB adapter is required for operatio n with the VR2W receivers because they use Bluetooth
communication. Others receivers may no t use Bluetooth communication and therefore would not need the
USB adapter.

3.2 Activate Wireless feature

The Bluetooth feature in a VR2W receiver must be activated before the VUE software will be able to f ind and
connect to the VR2W. Activation requ ires a sp ecially designed Communications Key (also referred to as
“Comm Key”).

The Communications Key is a stepped cylin der made of black plastic material. A strong magnet is contained
in the smaller end of the Comm Key and should be kept away from any magn etically sensitive materials. An
orange float is attached to the Com Key case for e asier handling and locating of the key. This key functions
with other VEMCO receivers that use a Comm Key, such as the VR4-UWM.

The Communication Key contains a
strong magnet. Do not put it near
magnet-sensitive materials, such as
CRT computer monitors or magnetic
stripes, as they could be seriously
damaged.

3.4 Record mode

The default operating mode of the VR2W is to record received pings and detections, even while connected to
VUE software. The VR2W enters Record Mode when any of the following events occur:

 The battery is installed
 A stu dy is started in the VUE software
 Bluetooth communication is closed while recording is paused

Bluetooth communication can close when any of the following events occur:

 The VR2W has received no communication from VUE for 10 minutes
 Th e R eceiver Tab in VUE software is closed by the user
 VUE closes communication automatically af ter 30 minutes of inactivity from the user (unless the

VUE option is disabled)

These events were chosen so that a VR2W receiver would always be deployed in Record Mode. The only
way a VR2W wouldn’t be in Record Mode is if the memory was full or the battery was removed (see section

5.1).

3.4.1 Start a Study

Setting up a study allows you to enter information in the VR2W that will aid you in
identifying its deployment location and even a description of the study, such as the
study’s title or other information. This information is stored in the VR2W and offloaded
with the data. It can be very useful when data is being organized in the VUE software.

After data has been collected by a VR2W, either during testing while in air or while in the water, that data
must be offloaded to be accessed and viewed. Data can only be offloaded from a VR2W recei ver while it is
in communication with the VUE software through Bluetooth®. Follow the steps below to offload data.

If a database is open in VUE when data is about to be offloaded, an additional dialog box appears asking if
the offloaded data should be imported directly into the open database. If “NO” is selected, then the file(s)
will be saved to the directory and in the format selected in the Offload tab of the Options window (see VUE
manual for details) and will not be imported to the database. The created file
choices are:

• VRL files only

• VRL files and CSV file

3.5.1 Disconnect communication with receiver

Click the “Close View” button (red box with white X) to disconnect the communication between
the VR2W and the VUE software. A window will appear to confirm that you want to close the
VR2 View window.

When the communication is disconnected, the VR2W resumes recording with the last study that was
initialized. Ending communication does not re-initialize the receiver.

3.5.2 Update Firmware

Firmware refers to the internal software that operates a VR2W receiver. It is not to be confused with VUE,
the PC software used to communicate wit h the receiver. Firmware updates are rare and wi ll occur to either
deal with a hardware change or occasionally for a significant addition to functionality. VUE 2.0.10 and
greater has the ability to alert you if there is a new f irmware update (feature can be disabl ed in the “Releases”
tab of the Options window).

3.5.2.1 Update Firmware Using Automated Notification

If when you establish communication with the VR2W (see section 3.3) you receive a message indicating
VUE has detected there is a firmware updat e, then use the instructions below to upd ate your firmware. To
learn what caused the firmware upgrade, use t he “Click here to see more” option in the not ice window.

4 Deployment

How a VR2W is deployed is driven by the environment it is being deployed in and the type of study being
performed. Some important points to keep in mind when designing a deployment plan for your VR2W
receivers are explained here. The common method for attaching a VR2W to a mooring line is also given,
along with the dimensions of the VR2W cases.

4.1 Deployment Facts/Tips

4.1.1 Mooring

VR2W receivers are moored in many confi gurations often reflecting the bathymetry and
oceanographic/weather conditions. A simple mooring design generally works well. However, in rougher
conditions, heavier weights and mooring lines are usually required. If a bottom mooring is desired, the VR2W
should be positioned above the floor such that it has an unobstructed “view” of tagged animals within their
expected acoustic range. Ensure the VR2W’s hydrophone is unblocked (e.g. do not position an air filled buoy
directly above the hydrophone) and free of any biofouling. In high flow locations, you may consider using
hydro dynamically shaped buoys and low profile anchors.

For the best horizontal range, mount the VR2W receiver in a
vertical position. If the VR2W is deployed close to the
bottom of the water, mount the VR2W with the hydrophone
pointing up to the surface. If the VR2W is deployed close to
the surface of the water, then position the VR2W so the
hydrophone is pointing down.

4.1.2 Spacing

CAUTION: The hydrophone must

be kept free of mooring lines
and obstructions. Objects

around the hydrophone will
adversely affect the detection
range of the VR2W receiver.

Receiver spacing is generally determined based on range testing and historical acoustic data. Our position is
that you should try to space receivers such that you achieve good detection probabi lity in most or all weather
conditions. It is not always necessary to have 100% coverage if you have several o ther locations where you
know the animals will be passing through. However, if you wish to accurately quantify the passing of
animals through receiver locations then you should strive for 100% detection
probability. Typical spacing is usually between 100 and 1,000 meters.

4.1.3 Biofouling

Some customers use a rubber shrink tape, such as DAFLEX ST250 Cold Shrink Tape, available from Digikey
(W211-ND), to prevent biofouling on the VR2W receiver. It can be used to cover the entire receiver case or
just the Comm Key Hole and does not leave a glue residue when it’s removed. Another option is to use an
antifouling paint, such as Interlux Micron CSC.

5 Maintenance

5.1 Battery Replacement

Replacing a battery in the VR2W requires four basic steps:

1. Opening the case (section 2.1)

2. Removing the battery

3. Inserting the battery (section 2.2)

4. Closing the case (section 2.3)

Most of these topics were covered when we first setup the receiver. The only remaining topic to cover is how
to disconnect and remove the battery.

5.2 O-ring Care

O-rings located in the end-cap of the VR2W case are crucial to the watertight seal of the receiver. Each time
an O-ring is disturbed, for any reason, it must be checked before the unit is sealed again. Something as
simple as a stray hair could be the differen ce between a successful study and a damaged r eceiver.

Just as the O-rings are vital to a good seal, so are the O-ring surfaces. These surfaces hold the O-ring in
position and must also be clean and damage free or the VR2W case could flood with water.

5.2.1 Remove O-rings

The O-rings must be removed from their grooves to allow the
O-rings and the grooves to be inspected and cleaned. Don’t use a
sharp object, which may damage the groove surface, when
removing the O-rings.

5.3 Storage

When a receiver will not be deployed for an extended period of time, remove the battery from the receiver
(section 5.1.1) to stop the VR2W from recording. This will prevent the possibility of recording pings from
noise sources during storage and also saves battery life.

Be sure to store the VR2W in a safe location where the case will not be damaged. Also be sure the
temperature of the receiver during sto r age does not exceed the operating temperatur e specified in section 9.4.

It is strongly suggested that the VR2W is not initialized prior to storage (data is not erased) and a backup of
all offloaded data is made immediately.

VEMCO - VR2W Manual 30

* Exceeds battery life of the VR2W-180kHz receiver

** Exceeds battery life of both the VR2W-69kHz and the VR2W-180kHz receivers

6 Additional Information

6.1 Flash Memory

The VR2W receiver uses a non-volatile Flash Memory (memory that can retain stored information even when
not powered) to store valid detections of coded transmitters and th e date/time at which the detection was
recorded. The VR2W will not continue to record received data once the memory is full.

A VR2W receiver contains either 8 MB or 16 MB of
memory depending on when it was manufactured. To
know the memory capacity of your receiver,
communicate with the receiver and check the
“Memory Size” value in the receiver information.

6.1.1 Time required to fill memory

A VR2W receiver with 8MB of memory is capable of storing more than 0.8 million valid detections while the
16 MB model can store more than 1.6 million detections. How long it takes to fill the memory depends on
how frequently the data is received. For example, if a valid detection is received every 20 seconds then it will
require approximately 365 days to fill the 16 MB VR2W memory. It will take less time if the detections are
received more frequently, as illustrated in the table below.

6.1.2 Time required to offload memory

The time required to offload the data from a VR2W depends on how much data is stored in the memory.
Table 6-2 below lists the approximate times required to offload data from a VR2W based on the amount of
data stored in memory. These times are approximations only – actual offload times can vary on a number of
factors, including the distance between the receiver and PC, the number of connected Bluetooth devices, and
any obstacles between the receiver and the PC th at can cause interference. Offload times can also vary if a
Vemco-supplied Bluetooth dongle is not being used (i.e. built-in Bluetooth radios in laptops).

6.3 Set Local options

The local options feature (icon shown at right) allows you to change which suppressed pop-up queries
are visible. This feature is only enabled on the ribbon if there are queries that have been suppressed.
To enable a query, select “Always Ask” and that query will be enabled the next time that feature is
used. For example, if “Confirm before closing VR2W” is selected, then a query will open the next
time a VR2W is closed.

Changing an action is also possible in the Control Setting window,
without enabling the query. For example, i f “No” was selected when
the “Import offloaded files into database” was disabled and you now
want to import the data without being queried each time, then click the
drop-down menu next to the answer and select “Yes” f r om the list.

Be sure to select “OK” to apply the changes.

6.4 Battery

The VR2W receiver is powered by a single “D” size 3.6 Volt Lithium battery with a
connector attached – the Tadiran TL-5930/F. Specifications for the Tadiran battery are
found in section 9.4 (Appendix). Other battery options, including a non-dangerous goods
battery option, are available directly from VEMCO. Contact VEMCO if you are
interested in more information on th ese alternatives.

An important feature of the approved lithium batteries is their voltage discharge
characteristics. These batteries provide a consistent voltage for most of the life of the
battery, as demonstrated with the blue line in the graph below. This characteristic allows the receiver to
operate at the necessary voltage levels longer than a battery with a more gradual vo ltage fall-off. This can be
seen by comparing when the blue and green l ines in the graph below cross the red “cut-off voltage” line.

As the graph illustrates, the battery voltage reported by a receiver may be at the correct level for proper
operation even when the battery is close to the end of its life. The voltage value reported by a VR2W
indicates the battery is at the proper voltage at the moment but does not give any indication of the remaining
life of the battery. For that reason, we suggest you write the date on the battery when it i s installed in the
receiver.

7 Common Questions

7.1 VUE related questions

7.1.1 How/when do I change my receiver code map?

Receivers must be configured with a Code M ap that defines which type of tags the receiver can detect. Check

www.vemco.com

Changing a receiver map is not done often and should be done with careful
attention. Setting up a receiver with an incorrect map may result in no detection
data, which would not be discovered until you retrieve the receiver and offload
your data.

When a receiver is configured with a new map, t he data logs are automatically
erased as they are no longer valid in th e presence of a different code map. Please
offload stored data prior to installing a new code map.

Detailed instructions on configuring your receiver with a new code map are located in section 6.6.

7.1.2 What is initialization?

for details on currently supported Code Maps and choosing the proper map for your study.

Setting up a receiver

with an incorrect map

may result in no

detection data.

Initialization, which is also referred to as starting a study, is an important step required to configure your
receiver correctly. During initialization, you can input the station name (location) where the VR2W will be
deployed and set the receiver clock based on your computer clock. The receiver
clock is always updated based on your PC clock during the initialization process.
This information will be resident with the VR2W and will be available during
offload, regardless of whether you use the same computer or not. Initialization
also erases the receiver log files so be sure to offload data from your receiver
before initializing it. When data is offloaded from a receiver, the VRL file
created contains information abou t how the receiver was initialized.

If a VR2W receiver is deployed without being initialized, the receiver will detect tags but the receiver will not
necessarily have the correct clock setting or map configuration required for proper data detection.

Offload your data first!
Initializing a receiver will

ERASE all data!

7.1.3 Why does VUE create two .vrl file types?

When a VR2W is offloaded, VUE creates a detecti on file and an RLD data file. Both files have the “.vrl”
extension. VUE only imports the detection vrl file (e.g., VR2W180_300000_20120120_1.vrl or
VR2W_300000_20120120_1.vrl ). The RLD data file (VR2W180-RLD_300000_20120120_1.vrl or VR2W­RLD_300000_20120120_1.vrl) is used by VEMCO for diagnostic purposes and should be archived in case it
is required by our Support Department. The RL D data files have the letters “RLD” in the filename.

VEMCO - VR2W Manual 39

7.1.4 What Date/Time format is my data stored in the receiver and

displayed in VUE?

All detection data and events are stored in the receiver in UTC (Coordinated Universal Time). UTC time is
calculated by your PC and stored in your receiver during initialization. Provided your computer time and the
Time Zone settings are correct and match, i.e. your computer time is correct for the time zone you have
selected, then your detection data will be stored in the correct UTC format at the time of initialization and
data offload.

In VUE, your data is also stored in UTC format in the database. You can choose to display your detections in
UTC, your local time or in a different time zone. I t is important to know that regardless of whatever display
format you choose VUE maintains the detection data in UTC.

Export: All detection data is exported only in UTC unless specified otherwise in VUE by selecting OP TIONS
– EXPORT – CUSTOM

Important: If you are importing detection data from an older format detection file (e.g., VR2*.000) you must
specify the time zone offset used when the receiver was initialized. Earlier VR2 receiv er s were most often
initialized with the current PC local ti me unless the PC local time was set to UTC. Please contact us if you
need assistance. Once these older files are imported into VUE, a new .vrl file will be created and all
timestamps will be in UTC.

7.1.5 What does the “Hide this (window) in future” mean?

There are a number of pop-up windows that appear while using the VUE software. These windows are
wonderful when you’re just learning the software or when you’ve been away from it for an extended period
of time, but they can be very annoying when you’re in the middle of a big
study. A number of these pop-up windows have a selection box in the bottom
left corner that say something along the lines of “Hide this alert in future.”
Selecting this option means that this window will not appear the next time the
task is performed. The pop-up windows can be returned by altering the local
options or selecting “Restore All Hidd en Dialogs” in the Options window (see
section 6.3). All hidden dialogs are restored automatically if one week elapses withou t VUE being opened.

7.1.6 How do I open the Options window?

The Options window is accessed by selecting the VUE menu
(circled in picture at right) and clicking the “Options” button at
the bottom of the menu box (see arrow in picture at right). The
Options window contains the following tabs: Display, Offlo ad,
Export, Devices, and Other. These are described in detail in the
VUE manual.

VEMCO - VR2W Manual 40

7.2 VR2W related questions

7.2.1 How much detection range can I expect from my tags and receivers?

Detection range depends on so many factors that it is difficult to estimate without knowledge of the
environment and prior experience with telemetry. Range depends on transmission power, signal absorption,
line of sight, reflection/refraction, multipath and environmental noise (man-made & natural), and the
receiving quality of the receiver/hydrophone. Typically areas that have clear water, sand or silt flat bottoms
and low current exhibit the greatest ranges. Conversely, areas with turbid water, complex rocky bottom
topography and high current exhibit low ranges. In all cases, extreme weather events and periods of high
wind (waves) may significantly reduce r ange.

In most cases greater transmission power output (dB) results in greater range. For example, in good
conditions a V7-VR2W range test could yi eld a range of 300-400 m and a V16-VR2W test could yield ranges
of 800-1200 m. There are some exceptions where high po wer and a reflective and low noise environment
may cause detection breakdowns.

Please try our range calculator at www.vemco.com/customer-service/?cs-tutorials
a guide. One should always perform range test ing to determine appropriate receiver spacing. For the
enthusiast who wants to learn more about sound propagation try the widely accepted reference on underwater
sound by Urick (1983). (Urick, Robert J. Principles of Underwater Sound, 3rd Edition. New York. McGraw­Hill, 1983.).

7.2.2 How long will my VR2W battery last?

, but only use the results as

The VR2W-69kHz receiver will typically last 15 months on a single Tadiran lithium battery (model TL­5930/F). The VR2W-180kHz receiver will last 8 months on a single Tadiran lithium battery.

TIP: Write the installation date on the battery so you know how long the battery has been in use.

7.2.3 Does receiver orientation matter?

Generally, in most cases we recommend that a VR2W should be orientated with the hy drophone looking
upwards. This is typically because receivers are commonly moored closer to the seafloor than the surface. In
some situations it may be beneficial to mount the receiver with the hydrophone pointing towards the sea floor.
If a receiver is mounted near the surface or a considerable distance from the sea floor and if the researcher is
monitoring benthic creatures a bottom looking receiver may perform better because your tagged animals will
not be in a shadow zone (under the receiv er ) . If receiver orientation is a concern we recommen d that you
perform range tests using both orientations.

7.2.4 At low tide my VR2W receiver will be exposed to direct sunlight,

does this matter?

The VR2W receiver has a recommended operating temperature of between -5 to 40°C. If t here is a chance
that your receiver will exceed either o f these temperatures please consider anot her location for the receiver.
Keep in mind that direct sunlight on the black case can cause the receiver’s inter nal temperature to be much
higher than the ambient temperature.

8 Troubleshooting

8.1 VUE related troubleshooting

8.1.1 Bluetooth Troubleshooting

VUE will display a Bluetooth® logo in the bottom right hand corner of the main VUE window when the
Bluetooth® adapter is detected and functional. If it is not detected, a red X will appear over the logo, as

shown in the sample on the right below.

Here are some things to check if VUE does no t detect a Bluetooth® adapter:

1. Is the VEMCO-supplied Bluetooth® adapter installed in a functional USB 2.0 High-Speed port on your

PC? If nothing happens when the adapter is plugged in, try a different USB port. VUE may work with
other adapters; however it is designed primarily for the adapters supplied by VEMCO.

2. Are you running the latest version of VUE? The model of VEMCO-supplied Bluetooth® adapter may

change from time to time. Updating to the latest version of VUE is the best way to ensure compatibility.
See the VUE Software section at www.vemco.com/downloads/

3. Are incompatible drivers installed? Th e Bluetooth® adapter must be configured to use drivers supplied

by Microsoft. These drivers are installed automatically in Windows 7 or manually through VUE in
Windows XP and Windows Vista. Do not install drivers from any other source. The drivers distributed
by the original manufacturer of the Bluetooth® adapter may not be compatible with VUE. If you
previously installed the Bluetooth® software, it must be removed before installing the Microsoft d r ivers.

To install the Microsoft drivers in Windows XP or Windows Vista, use the Install Bluetooth® Drivers
tool located under "Tools" in the VUE menu (shown below on left). You will require administrator
access to the PC to install the device driver.

If no compatible adapter is found, your Bluetooth® adapter or USB port is not functional.

for the latest download.

the PC to install the device driver.

VEMCO - VR2W Manual 42

4. Is the BTH.INF file missing? This driver info r mat ion file is a standard part of the Windows system,

however some computer manufacturers rename or delete it to force customers to use a particular set of
Bluetooth® drivers. This file should be located at C:\windows\inf\BTH.INF. If it is not present, then it
may have been renamed to C:\windows\inf\BTH.BAK. Simply rename this file by replacing .BAK with
.INF and rerun the VUE driver installation.

5. Remove the Bluetooth adapter and re-insert it. When laptops go into sleep mode and then re-awakened,

the connection between VUE and Bluetooth is not re-established. The Blue LED on your Bluetooth
adapter will flash when connected to VUE.

6. Windows occasionally keeps Bluetooth Devices op en in the Control Panel which interrupts VUE

communication. Open the Control Panel. If your Control Panel is set to Classic View, select Bluetooth
Devices. If your Control Panel is set to Category View, select Network & Internet Connections category,
then Bluetooth Devices. If a VR2W is listed there, highlight it, remove it and try communicating to VUE
again.

7. Though quite rare, laptops with an internal Bluetooth adapter can sometimes interfere with the VEMCO-

supplied Bluetooth USB adapter. If this is the case, you have to disable your laptop’s onboard Bluetooth
adapter under the Windows’ Device Manager. You will require administrator access to your laptop in
order to disable devices.

To access the Device Manager when the Control Panel is in Classic View, select System, then Har dware,
then Device Managers and then Bluetooth Radios. To access the Device Manager when the Control Panel
is in Category View, select Performance & M aintenance, then System, then Hardware, then Device
Managers and finally Bluetooth Radios.

Highlight any radio devices other than VEMCO devices and select Disable under the Action menu. Do
not disable the Microsoft Bluetooth Enumerator. Remove the VEMCO Bluetooth adapter from the
USB port and reinsert it. Only the VEMCO Adapter and Microsoft Bluetooth Enumerator should appear
under Bluetooth Radios (all others must be disabled). Bluetooth Device (Personal Area Network) #3 and
Bluetooth Device (RFCOMM Protocol TDI) #3 will appear under Network adapters.

8.1.2 I cannot connect to my VR2W receiver

First confirm that your Bluetooth connection between VUE and your VR2W receiver is functional. If this
Bluetooth connection is functioning correctly, try replacing the VR2W battery in the VR2W with a new

battery. If you are still unable to communicate with the unit, please contact VEMCO to receive RMA
information and send the unit back to VEMCO for assessment/repair.

8.1.3 These detected ID’s don’t belong to me

We would be very pleased to help connect you with th e owners of any unknown IDs. Please send a list of the
unknown ID’s and all associated receive r .vrl files to the VEMCO support team. VEMCO will first review
the data to identify false detections and provide you with a false detection report. Then we’ll contact the tag
owners for all the valid detections and request that they contact you directly. Please indicate if you are
willing to release your email address.

VEMCO - VR2W Manual 43

8.2 VR2W case related troubleshooting

8.2.1 The threads have been damaged

It’s very important that the threads on the end-cap are not dented or the outer cylinder will not thread onto the
end-cap properly. If the threads on the end -cap are slightly dented, use a sharp knife, such as an X-Acto
knife, to remove the deformed plastic until the sides of the thread are smooth and below the normal line of the
thread. It is important that there is nothing sticking out of the thread to damage the thread on the outer
cylinder or prevent the case from closing.

8.2.2 I think the case might be pressurized

When handled correctly, the VR2W pressure case and seal have a static depth rating of 500 meters (730 psi).
If the receiver experiences a pressure greater than this, then water may enter the case. NOTE: Physical
shocks to the receiver, such as bumping into a solid object, when it is at any depth can result in a considerably
higher pressure on the casing than just the depth pressure. Also, if the O-rings or their mating surfaces are
dirty or damaged, then water may enter the receiver case.

If water enters the receiver case under high pressure and the Release Valve was unable to open and equalize
the pressures, then some water and compressed air may still be in the case when it is returned to the surface.
This can be identified by its increased weight and a sloshing sound when the case is moved. The VR2W case
will also be very difficult to open, if at all possible. If you are suspicious there is compress ed air in the
receiver case, then check for air or water leaking from seam in the case where the end-cap and outer cylinder
meet.

To check for... then...

water leakage

air leakage

dry the seam completely and watch for drops of water around
the seam

spread soapy water around the seam and watch for bubbles
indicating air escaping

If air and/or water are found leaking from the receiver case, do not attempt to remove the end-cap. Instead,
place the receiver in a safe place and cover it with a protective layer of towels, tarpaulins, etc. until the

leaking stops. If water is still in the case after t he air and/or water have finished leaking from the
case, then attempt to open the case with the steel rod kit. If it will open, do so very slowly to allow
the compressed air to escape. If the case will n ot open using the steel rods, then it is under a greater
pressure than will allow the case to open. C ontact VEMCO for further instructions.

When the pressure has been released from the VR 2W case, carefully unscrew the end-cap from the outer
cylinder (section 2.1). Use fresh water to rinse the internal parts of the VR2W while avoiding skin contact
with any battery electrolyte that may have escaped from the battery.

Do not attempt to re-use the VR2W receiver after water has been insid e the case. The internal casing
protecting the electronics is not waterproof and the electronics have been destroyed by contact with water.

9.1 VR2W Metal/PVC Casing

The VR2W receiver is housed in a black pl astic high pressure case as shown in the photo below. The outer
cylinder is removed from the receiver to inst all the D-cell Lithium battery, revealing the internal casing
protecting the electronics. The older b lack VR2W receivers have a metal/PVC internal casing, which is
explained in this document. The metal/PVC internal casing has an O-ring between the metal internal casing
and the PVC battery cup to reduce vibration and is not used for water protection. Do not grease this O-ring.

The procedure for opening a black VR2W is th e same regardless of the type of internal casing so we will
begin with an open VR2W, shown below. Details on how to open the receiver are found in section 2.1.

2. Press the back of the battery towards the body of the VR2W until the battery is not

pressing against the O-ring. There is a spring at the other end of the battery cup so
the battery will move.

3. Slip the O-ring from its groove as shown in the photo. The O-ring’s purpose is to

hold the battery from sliding out the end of the battery cup.

4. Slide the O-ring along the battery’s connector wires so they are separated f r om

each other.

5. Tip the VR2W so the battery slides out of the battery cup.

Desiccant pack in place

Hand tightening the case

A desiccant pack has been included in the bottom of the VR2W to reduce the occurrence of
condensation in the VR2W. This pack should remain in the receiver case during storage and
deployment.

We recommend that you replace the desiccant pack with each deployment and with each
battery replacement cycle.

More information on the availability and usage of these packs is located

Insert Battery

1. Remove the O-ring from the groove in the battery cup if it hasn’t already

been removed.

2. Slide the wire-free end of the new battery into the battery cup. The

connector wires should stick out the battery cup.

3. Thread the connector wires through the O-ring.

4. Press on the battery until the end of the battery is b elow the O-ring

groove.

5. Squeeze the O-ring into an oval shape and push it into the groove in the

battery cup as shown in the photo. Do not grease this O-ring.

6. Make sure the connector wires are not pinched in any way, especially between the

O-ring and the battery or case. Pinched wires c an break internally and disrupt power
to the receiver.

7. Connect the Tadiran TL-5930/F battery to the VR2W connector in the proper

orientation. The two connector halves should lock together with a little click.

Close the VR2W Case

The procedure for closing the VR2W with metal/PVC internal casing is very similar to the procedure with a
plastic internal casing. The only difference is the placement of the desiccant pack . That difference is covered
here but the rest of the steps required to close t he case are found in section 2.3.

1. Position the battery wire so it’s away from the end of the batter y cup as shown in the photo (at right).

2. Hold the receiver’s inner casing so the hydrophone is pointing down.

3. Place a new desiccant pack on top of the battery compartment and fold the ends of the pack over onto

itself.

4. Fold the battery wires over so they are lying on top of the desiccant pack. This is important to protect the

wires from being pinched inside the tube.

5. Slide the cylinder down over the inner casing until the first threads are inside the outer cylinder.

6. Turn the end-cap in a counter-clockwise direction with your hand until it becomes too hard to turn.
