1 Introduction

1.1 System Overview

The VR2 is a submersible, acoustic receiver capable of identifying VEMCO coded transmitters. The receiver
operates on a factory set frequency and can decode various combinations of sensor and pingers. The VR2
receiver consists of electronics and hydrophone housed in a cylindrical corrosion resistant case. Its features
include a Smart LED (light emitting diode), two megabytes of data storage, a resume study feature, and a
replaceable battery (a single Lithium cell ) .

The VR2 records the pinger identification code number, date and time of each detection. This information is
stored in the receiver’s memory for later ret r ieval using a VR PC interface and a PC computer r unning VUE
software.

NOTE: As of January 2007, the VR2PC software has been replaced with the VEMCO User
Environment (VUE) software. VUE software is available at www.vemco.com/downloads/.

1.2 VR2 Case

The VR2 receiver is housed in the black plast ic high pressure case. The case consists of an out er 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.

A crucial part of the VR2 is the hydrophone, located at the top of the receiver. The hydr ophone 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 detecting tags.

The VR2 case only needs to be opened when the battery must be installed or replaced.

When the VR2 is powered (see the Battery section), the Smart LED will emit three
quick flashes. After ten seconds, two long flashes will indicate that necessary
information was read from memory and the receiver is ready for initialization. The LED
will not flash again until the receiver has been in itialized. When the receiver has been
initialized (record mode), the LED emits two quick flashes every five seconds. A
received acoustic ping will be indicated with a short dim flash from the LED. A long
bright flash following a sequence (6-7) of short flashes indicates that a transmitter ID
code has been received and stored to memory. Two flashes every ten seconds from an initial ized receiver
indicates that the memory is full.

1.2.2 Communication Probe Receptacle

The VR2 receiver has a receptacle for the communication probe from the VR
PC computer interface. The receptacle, called the probe hole, is located on
the end-cap and is identified in the first photo on the previous page. The
probe hole is stepped to ensure that the communication probe is inserted
from only one direction. Remove any marine growth from the receptacle
before inserting the probe. Ensure that the probe is inserted until the O-ring
on the probe is fully seated.

VEMCO - VR2 Manual 3

2 Getting Started

The list below is designed for users who are familiar with VEMCO equipment. Please read the manual
completely before using the VR2 receiver.

1. Install VUE software on a computer (see section 3.1).

2. Setup sensor transmitter information in VUE software (see VUE softwar e manual). This does not

have to be performed before deployment.

3. Open VR2 case (see section 5.1.1).

4. Install battery in VR2 receiver (see section 5.1.3).

5. Inspect and clean O-rings (section 5.2).

6. Close the VR2 case (section 5.1.4).

7. Perform an air test (see section 2.1.1).

8. *Initialize VR2 to begin recording study (see section 3.5). This will also erase the data recorded

during the air test.

9. Remove communication probe from VR2 receiver.

10. Deploy VR2 receiver (see section 4).

11. Retrieve VR2 receiver.

12. Establish commu nication between VR2 and VUE (see section 3.3).

13. *Offload data f r om VR2 receiver (see section 3.4).

14. Remove communication probe from VR2 receiver.

15. If study is continuing, re-deploy VR2. If study is not continuing, remove battery to stop recording

(see section 5.1.2).

*CAUTION: Ensure that your PC clock time is accurate! The VR2 has an internal clock that will be

synchronized with the PC clock. At the time of Initialization or Study Start, the VR2 records the PC
clock time in its memory. When the study is finished and data is downloaded, the VUE software
records the VR2 start and end times alon g with the PC clock time in the VUE database. Users should
be aware that the VR2 end time will most likely be different from the PC clock time. If users wish to
time- correct transmitter detection times, then they must ensure that the PC clock time is accurate at
Initialization and Study End. If more than one computer is used to initialize the receivers and load
data, then make sure the PC clock time is accurate on all computers.

VEMCO - VR2 Manual 4

Receiver Control Window

2.1 Testing

Before deploying a VR2 receiver, we advise you conduct a test with a tag to verify that the VR2 is operating
properly. This test also creates a VRL file ( detection data file) containing all the configuration information
for this receiver – handy to keep as a record of the receiver’s configuration.

Tests should be performed in both air and water.

2.1.1 In-Air Test

The VR2 can detect coded pingers in air, but at a much reduced range (up to three
meters) compared to testing in water. Perform air tests away from electrical noise
sources such as motors, PC screens, or fluorescent lights. Before beginning th e test,
ensure the clock of the PC to be used is set to the correct time. Follow the steps
listed:

For VR2 receivers with firmware versions 1.01 or lower:

1. Open VUE software on your computer.

2. Insert the VR PC interface probe into the VR2.

3. Initialize a study and remove the prob e.

4. Activate a coded pinger transmitting o n the same frequency that the VR2 is set to receive (typically 69

kHz; refer to Transmitter Specifications manual for the pinger information). A VR100 receiver may be
used to audibly confirm when the pinger is transmitting.

5. Lay the VR2 receiver on its side with the transducer (pointed end) past the edge of a table.

6. Position the pinger up to 1 meter from the transducer.

7. Watch the LED on the VR2 receiver. The LED wil l flash briefly for each acoustic ping received. A long

bright flash occurs when the receiver has successfully recorded the ID.

8. After a few transmissions have been recorded, connect the VR2 to the VR PC interface and download the

data.

For VR2 receivers with firmware versions 1.02 or higher:

1. Open VUE software on your PC.

2. Insert the VR PC probe into the Probe Hole in the VR2.

3. When the receiver appears in the selectio n tree on the left

side of the window, double-click the receiver name to open
the Receiver Control Window.

4. Activate a coded pinger transmitting o n the same frequency

that the VR2 is set to receive (typically 69 kHz; refer to
Transmitter Specifications manual for the pinger
information). A VR100 receiver may be used to audibly
confirm when the pinger is transmitting.

5. Lay the VR2 receiver on its side with the transducer

(pointed end) past the edge of a table.

6. Position the pinger up to 1 meter from the transducer. Watch the LED on the VR2 receiver. The LED

will flash briefly for each acoustic pulse received. A long bright flash occurs when the receiver has
successfully recorded the ID memory.

Perform air tests
away from electrical
noise sources such
as motors, PC
screens, or
fluorescent lights.

VEMCO - VR2 Manual 5

7. Watch the LED on the VR2 receiver. The LED wil l flash briefly for each acoustic ping r eceived. A long

flash occurs when the receiver is writing information to the memory.

8. Verify that the “Detections” and “Pings” numbers in the Receiver Control Window are increasin g.

Stop recording and retrieve the stored data (see the VUE manual for details).

2.1.2 In-Water Test

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 VR2 receivers in the environment in which they are moored.

1. Initialize a study with your watch synchronized to the PC time.

2. Perform a Range Test. Details pertaining to Range Testing are found at www.vemco.com/customer-

service/?cs-tutorials.

3.4 Offload Data from VR2 Receiver

Select the radio button next to “Retrieve Data” in the VR2 Control Tasks list and then select “Next” to open
the “Retrieve receiver data” window ( shown at right).

“Automatically importing the VRL file into current
database” allows the data to be viewed immediately after
the data are recovered. For large data files, you may
choose to unselect this and import the data later. This will
speed up the offload process.

This option is provided to adjust the times to UTC. This is
only necessary if the receiver was initialized using the
VR2PC software. If the VR2 was initialized usin g the
VUE software, the times are already UTC and an
adjustment is not necessary.

To adjust the times to UTC, first click the “Adjust data
times to UTC” box. Select the correct offset based on the
difference between UTC and the receiver’s time. A
suggested offset is shown based on the PC clock and the
receiver’s clock. The PC UTC time is shown on the left and the receiver’s time is shown on the right. Set the
value in the “Offset to UTC” box to the hours that must be added or subtracted from the receiver’s time to
obtain the correct UTC time.

After the desired retrieval settings are made, the “Execute” button will begin t he process.

The data are stored in a VRL file which can b e imported later into this or another VUE database by using the
Import File feature explained in the VUE software manual.

VUE software allows you to communicate with up to seven receivers simultaneously. Since your PC can talk
to as many VR2 units as are connected to the PC, it is important that you ensure you are communicating with
the correct unit, particularly before initializing and erasing receiver memory files.

It is vital that the PC clock be
correctly set to your local
time, including time zone,

before the VR2 is initialized.

Initializing the VR2 will erase
the receiver’s memory.

Retrieve all detection logs
before the VR2 is initialized.

3.5 Initialize VR2 Receiver

Initializing a receiver clears the receiver logs, sets the receiver clock,
and stores configuration information into the receiver memory.
Initialization is required to put the VR2 receiver into record mode.

Select the radio button next to “Initialize Receiver” in the VR2 Control Tasks list and then select “Next” to
open the “VR2 Initialization” window (shown below).

The VR2 does not support the use of a separate Station (Location) Name stored into memory, however the
“Study Description Field “ can be used to include both a receiver name and location details.

A brief description or name of the study can be saved in the receiver’s memory and associated with the data.
This could be the location where the VR2 was deployed or the name of the study being conducted.

The receiver clock is to the PC clock and is used to time stamp the detections as they are stored in memory.
This is why it is vital that the PC clock be correct, including time zone, before the VR2 is initialized.

The initialization process clears the memory from the receiver,

NOTE: You will not be able to proceed un less Set Receiver Clock and Erase logged Data are both selected.

After the desired study description has been entered and Set

click the “Execute” button to begin the initialization process.

Once you have initialized a receiver and are ready for
deployment, it is wise to test with a transmitter and then to
offload (retrieve) the data. This will create a VRL file which
contains all the configuration information for this receiver.
This file can be read later if required to verify that the VR2

4 Deployment

How a VR2 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 VR2
receivers are explained here. The common method for attaching a VR2 to a mooring line is also given.

4.1 Deployment Facts/Tips

4.1.1 Mooring

VR2 receivers are moored in many configurations 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 VR2 should be positioned above
the floor such that it has an unobstructed “view” of tagged animals within their expected acoustic range.
Ensure the VR2’s hydrophone is unblocked (e.g. do not position an air filled buoy directly above the
hydrophone) and free of any significant biofouling. In high flow locations, you might conside r us ing hydr o
dynamically shaped buoys and low profile anchors.

For the best horizontal range, mount the VR2 r eceiver in a
vertical position. If the VR2 is deployed close to the bottom,
mount the VR2 with the hydrophone pointing up to the
surface. If the VR2 is deployed close to the surface in deep
water, you could position the VR2 so the hydrophone is
pointing down. Conduct range testing to determine the
optimum orientation.

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 VR2 receiver.

Receiver spacing is generally determined based on range testing and historical ac oustic data. Our position is
that you should try to space receivers such that you achieve good detection probability in most or all weather
conditions. It is not always necessary to have 100% coverage if you have several other 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 VR2 receiver. It can be used to cover the entire receiver case or
just the Probe Hole and does not leave a glue residue when it’s remo ved. Another option is to use an
antifouling paint, such as Interlux Micron CSC.

5.1 Battery Replacement

The VR2 receiver is housed in a black plastic high pressure case with an outer cylinder that is removed from
the receiver, revealing the internal casing protecting the electronics and allowing access to the D-cell Lithium
battery. The metal/PVC internal casing has an O-ring between the metal internal casing and the PVC battery
cup. This O-ring reduces vibration. It is not used for water protectio n. Do not grease this O-ring.

Replacing a battery in this VR2 requires four steps:

1. Opening the case (section 5.1.1)

2. Removing the battery (section 5.1.2)

3. Inserting the battery (section 5.1.3)

4. Closing the case (section 5.1.4)

5.1.1 Open the VR2 Case

electronics is not waterproof. Water, even
condensation from a humid environment, wi l l

Two steel rods are necessary to properly open and close the VR2 case. Every shipment of new VR2 receivers
includes a pair of steel rods.

1. Make sure there is absolutely no water on or near the VR2 case. Water, even in a small

quantity, can damage the VR2 internal circuits beyond repair. If the VR2 is attached to
a wet rope, remove the receiver from the rope before opening the case.

This also means that the electronics cannot b e exposed to a sudden change in
temperature and humidity which may cause condensation to develop on the
electronics.

with any water or the receiver will be damaged. For this reason, VEMCO recommends the
VR2 be opened in a controlled environment and not in the field or on the deck of a boat.

2. Place the VR2 on a clean, flat surface so the hydrophone (tapered end) is hanging

over the edge enough that the large hole is past the edge of the surface. DO NOT
let the receiver fall off the surface. TIP: A non-slip surface, such as a rubber mat,
helps keep the VR2 in place while opening it.

3. Insert one steel rod into the hole that runs through the diameter of the case near

the flat end of the VR2. Position it so most of the rod is on the left side of the
receiver as shown.

4. Place a hand on the back of the receiver to hold it in place. The back of the

receiver often “jumps” during Step 6 so be pre pared.

VEMCO - VR2 Manual 16

DO NOT impact the threads on the end-cap or they will dent

5. Insert the other steel rod into the hole in the Probe Hole on the end-cap

of the receiver and hold on to the rod – it will slide right through the hole
and potentially damage something below. Make sure the rod is fully
inserted into the hole or damage may occur to the Probe Hole.

6. Apply pressure to the rod in the Probe Hole to turn it in a counter-

clockwise direction when you are facing the hydrophone. The rod at the
back of the receiver acts as a brace while you apply pressure, but be
careful of it “jumping” off the flat surface.

7. Unscrew the hydrophone end from the main body.

8. Remove the steel rods from the VR2 case and set them aside.

9. Slide the end-cap and cylinder apart until the battery compartment has cleared

the cylinder. Be very careful not to damage the threads on the end-cap or the
VR2 won’t close and seal properly.

and prevent the VR2 case from closing. See section 8.2.1
for tips on thread care.

5.1.2 Remove Battery

1. Press the release lever on the battery connector and pull the connector apart. A

small and a small flat screw driver may help release the lever.

2. Press the back of the battery towards the body of the VR2 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 from

each other.

5. Remove the battery.

VEMCO - VR2 Manual 17

A desiccant pack has been included in the bottom of the VR2 to
reduce the occurrence of condensation
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.

5.1.3 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 cu p. 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 below 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 p inched in any way, especially between the

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

7. Connect the Tadiran TL-5930/F battery to the VR2 connector in the proper orientation.

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

5.1.4 Close VR2 Case

Before deploying or storing a VR2 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. Important information about
storing a VR2 is found in section 5.4.

1. Position the battery wire so it’s away f rom the end of

the battery cup.

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.

Improper care of the O-rings and their
mating surfaces can result in water
leaking into the receiver casing,
destroying the electronics.

6. Turn the end-cap in a counter-clockwise direction (when looking at the

hydrophone) with your hand until it becomes too hard to turn.

7. Place the VR2 on a clean, flat surface so the hydrophone is hanging over

the edge. DO NOT let the receiver fall off the surface.

8. Insert one steel rod into the hole that runs through the diameter of the case

near the flat end of the VR2.

9. Insert the other steel rod into the wider end of the Probe Hole on the end-

cap of the receiver. Make sure the rod is fully inserted or damage may
occur to the Probe Hole.

10. Place a hand on the back of the receiver to hold it in place.

11. Apply pressure to the rod in your hand to turn the end-cap in a clock-wise

direction when you are facing the hydrophone. The rod at the flat end of
the receiver acts as a brace while you apply pressure.

12. Continue moving the rod until the end-cap suddenly stops turning. DO

NOT continue to apply pressure on the rod or the receiver case will be
damaged. The gap between the end-cap and the outer cylinder will be
closed. Do not over tighten the end-cap or the receiver case will be damaged.

13. Remove the steel rods from the VR2 case.

14. Initialize the receiver (see section 3.5).

15. Deploy the VR2 receiver.

The VR2 must be initialized to

conduct a new study after the

battery has been replaced.

5.2 O-ring Care

O-rings located in the end-cap of the VR2 case are crucial to the watertight seal of the receiver. Each time a n
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 difference bet ween a successful study and a damaged receiver.

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 VR2 case could flood with water.

1. Use a lint-free cloth to grip two points on the O-ring with your thumb and finger, approximately 5 cm

apart. It’s best to start with the O-ring farthest from the case threads.

2. Pull your thumb and finger towards each other while maintaining your grip on the

O-ring. This requires pressure against the O-ring and should produce a loop of
exposed O-ring.

3. Grab the exposed O-ring and pull it away from the end cap, so it moves along the

body of the receiver.

4. Repeat Steps 1 -3 for the other O-ring.

5. Clean any O-ring grease on the plastic casing.

5.2.2 Clean O-ring Surfaces

The O-ring surfaces must be clear of all debris and dirt.
An O-ring surface is any surface the O-ring t ouches. The VR2 has three, the two grooves the O-ring s sit in

and the smooth area inside the Outer Cylinder that sits between the threads and the end of the cylinder.

It is vital that all O-ring surfaces are clean and damage free or water may work its way inside the case and
destroy the electronics within th e VR 2 receiver.

VEMCO - VR2 Manual 20

CAUTION: O-rings can stretch with cont i nued handling.

1. Use a lint-free cloth to clean the old grease and any debris from the O-rings and the O-ring surfaces. A

lint-free swab is very helpful for cleaning inside the grooves.

2. Inspect the O-ring surfaces for any scratches or debris – use a magnifying glass and a bright light.

Scratches in the O-ring groove would allow water to bypass the O-ring. If you find debris (dirt, dust,
hair, etc) inside a groove, then use a lint-free swab to remove it. If you find a scratch in any of the O-ring
surfaces, then contact our Support department.

3. Inspect the O-rings for debris and for any damag e. If there is any question

about the condition of an O-ring, we recommend it be replaced rather than
risk damage to the receiver and therefore your data. O-rings can be
purchased for VEMCO or locally. The replacement O-rings must be
PARKER #2-143 O-RING, 70 Bn NITRILE.

We advise that undamaged O-rings not be used
for more than three deployments.

4. Use your gloved fingers to evenly spread O-ring

grease (we suggest Molykote 55) over t he entire
surface of the O-ring until the O-ring is slippery
but doesn’t have clumps of grease on it. Too
much grease can cause an O-ring to “pop” out of
the groove while the case is being closed, giving
little protection from water entering the VR2.

5. While you have grease on your glove, spread a very thin layer of the grease –

enough to make the area appear shinny – around the O-ring surface on the
inside of the Outer Cylinder (the smooth area bet ween the threads and the end
of the case). You shouldn’t be able to see grease globs or streaks. This thin
layer of grease will make screwing the two pieces together again much easier
and will also help to create a better seal.

VEMCO - VR2 Manual 21

5.3 O-ring Installation

Now that the O-rings and O-ring surfaces are clean and prepared, we’re ready to install the new O-rings into
the case.

1. Slowly move one of the O-rings along the body of the VR2 to the end cap and

carefully lift it over the threads.

2. Push the O-ring into the first O-ring groove and check the circumference of

the receiver to make sure the entire O-ring is in the groove.

3. Slowly move the second O-ring over the VR2’s body, over the threads, and into the

remaining groove. Check that it’s entirely in the groove.

4. Clean any grease that may have gotten on the body of the receiver.

5. Place the receiver on a clean surface so the O-ri ngs remain debris and damage free.

5.4 Storage

Remove the battery from the receiver (section 5.1.2) to stop the VR2 from recording. This will prevent the
possibility of recording pings from noise sources during storage while saving battery life.

Be sure to store the VR2 in a safe location where the case will not be damaged. Also be sure th e temperature
of the receiver during storage does not exceed the operating temperature specified in section 9.3.

Do not initialize the VR2 prior to storage (data is not erased). Backup all offloaded data as soon as possible.

VEMCO - VR2 Manual 22

6 Additional Information

6.1 Flash Memory

The VR2 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 the date/time at which the detection was
recorded. The VR2 will not continue to record r eceived data once the memory is full. The memory is
capable of storing more than 300,000 valid detections. If a valid detection is received every 45 seconds it will
require approximately 156 days to fill the VR2 memory (see table below).

Time required to fill 2 MB memory based on various detection times.

6.2 Resume Study

After a VR2 Receiver has been initialized, it will continue to record data until the power is disconnected
(battery removed) except when it’s connected to the VR PC interface. When the VR PC interface’s probe is
inserted in the VR2 receiver, the study is stopped. Sixty seconds after the probe is removed from the receiver
the study will resume, unless the memory is full. This feature simplifies the process of downloading data
while in the field because receivers don’t need to be re-initialized before being re-deployed. If a study is
completed when the data is downloaded and the VR2 will not be deployed in the near future, remove the
battery from the receiver (see Battery secti on) to stop the receiver from recording.

6.3 Change VR PC Battery

To change the 9 volt battery in the VR PC computer interface:

1. Disconnect the serial cable between the VR PC and the computer.

2. Turn the interface case over and slide the b attery cover away from the case.

3. Remove the battery from the case and disconnect it.

4. Connect the replacement 9 volt alkaline battery,

5. Insert the battery into the case and replace the battery cover.

7 Common Questions

7.1 VUE related questions

7.1.1 What is initialization?

Initialization, which is also referred to as starting a study, is a vital step required to configure your receiver
correctly. A VR2 receiver will not detect tags until it is initialized. During initialization, you can also input
the station name (location) where the VR2 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 VR2 and will be
available during offload, regardless of whether you use the same computer or not.

Initialization also erases the receiver’s memory. Offload data from your receiver
before initializing it. When data is offloaded from a receiver, the VRL file created contains information about
how the receiver was initialized.

7.1.2 Why does VUE create two .vrl file types?

VR2 will not

detect tags until

it is initialized

When a VR2 is offloaded, VUE creates a detection file and an RLD data file. Both files have the “.vrl”
extension. VUE only imports the detection vrl file (e.g., VR2_2693_20120120_1.vrl or
VR2_2693_20120120_1.vrl ). The RLD data file (VR2180-RLD_2693_20120120_1.vrl or VR2­RLD_2693_20120120_1.vrl) is used by VEMCO for diagnostic purposes and should be archived in case it is
required by our Support Department. The RLD data files have the letters “RLD” in the filename.

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

displayed in VUE?

All detection data and events are stored i n the receiver in UTC (Coordinated Universal Ti me). 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. Exception: If a VR2 is initialized u sing older VRPC software the VR2 will likely store the local
time.

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 what ever display
format you choose the detection data is stored in UTC in the VUE database.

Export: All detection data is exported only in UTC unless specified otherwise in VUE by selecting OPTIONS
– 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 receiver s were most often
initialized with the current PC local ti me unless the PC local time was set to UTC. Please co ntact us if you

VEMCO - VR2 Manual 24

need assistance. Once these older files are imported into VUE, a new .vrl file will be created an d all
timestamps will be in UTC.

7.1.4 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 , Offl oad,
Export, Devices, and Other.

7.1.4.1 Display of location, units, and time

The Display tab in the Options window allows the user to select
the format of various display options.

7.1.4.2 Offload data settings

The Offload tab in the Options window allows the Receiver Offload Storage Folder location to be changed by
clicking the “Change” button and selecting a different storage location for the offloaded data files. The
default directory location is created in “…\My Documents\Vemco\VUE\ReceiverLogs\”

Also, the offloaded file format can be chosen f r om the choices listed: VRL files only, VRL fi les and CSV
files, or VRL files and legacy VR2 files.

7.1.4.3 CSV file settings

The format of the CSV files created in VUE can be changed from the default format to either the Version 1.0
format or to a custom format in the Export tab of the Options window.

7.1.4.4 Other settings

The Other tab in the Options window allows the last database that was launched in VUE t o be automatically
open the next time VUE is opened. Also, th e default options settings and the hidden dialogs can be restored
to their default settings.

VEMCO - VR2 Manual 25

7.2 VR2 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 k nowledge 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/hyd r ophone. Typically areas that have clear wat er , 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-VR2 range test could yield a range of 300-400 m and a V16-VR2 test could yield ranges of
800-1200 m. There are some exceptions where high power 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 testing to det ermine appropriate receiver spacing. F or 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 VR2 battery last?

, but only use the results as

The VR2 receiver will typically last 15 months on a single Tadiran lithium battery (model TL-5930/F). TIP:
Write the installation date on the battery so you know how long the battery has been in use. We recommend
changing the battery within 12 months.

7.2.3 Does receiver orientation matter?

Generally, in most cases we recommend that a VR2 should be orientated with the hydrophone 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 recommend that you
perform range tests using both orientations.

7.2.4 At low tide my VR2 receiver will be exposed to d irect sunlight, does

this matter?

The VR2 receiver has a recommended op er ating temperature of between -5 to 40°C. If ther e is a chance that
your receiver will exceed either of these temperatures please consider another location for the receiver. Keep
in mind that direct sunlight on the black case can cause the receiver’s internal temperatu r e to be much higher
than the ambient temperature.

VEMCO - VR2 Manual 26

8 Troubleshooting

8.1 VUE related troubleshooting

8.1.1 I cannot connect to my VR2 receiver

First, confirm that the 9 Volt battery in the VR PC does not need to be replaced. If this was no t the problem,
then confirm that the VR PC is connected to the correct Com port on the PC. Also, it’s possible that the
probe on the VR PC is not inserted far enough into the Probe Hole on the VR2. If you are still unable to
communicate with the unit, please conta ct VEMCO to receive RMA information and send the unit back to
VEMCO for assessment/repair.

8.1.2 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 repo r t. Then we’ll contact the tag
owners for all the valid detections and request that they contact you directly . Pl ease indicate if you are
willing to release your email address.

8.2 VR2 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 VR2 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 hig h pressure and the Release Valve was unabl e to open and equalize
the pressures, then some water and compressed air may still be in the case when it is return ed to the surface.
This can be identified by its increased weight and a sloshing sound when the case is moved. The VR2 case
will also be very difficult to open, if at all possible. If you are suspicious there is compressed air in the

VEMCO - VR2 Manual 27

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 wi th 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 sl owly 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. Contact VEMCO for further instructions.

When the pressure has been released from the VR 2 case, carefully unscrew the end-cap from the outer
cylinder (section 5.1.1). Use fresh water to rinse the internal parts of the VR2 while avoiding skin contact
with any battery electrolyte that may have escaped from the battery.

Do not attempt to re-use the VR2 receiver after water has been inside the case. The internal casing protecting
the electronics is not waterproof and the electronics will be destroyed by contact with water.
