Introduction

1
The Fathom software has been developed to aid in preparing your HR2 receivers for deployment, retrieving data from your HR2 receivers, and in visualizing and exporting data from your HR2, VR2W, VR2AR, VR2Tx, and VR4-UWM receivers when your study is complete.
Fathom software key features
l Initializing, configuring and uploading data from VEMCO HR2 Receivers
l Viewing live detection data in real time (great for testing and troubleshooting)
l Integrated easy-to-search help (for both the Fathom software and the HR2 Receiver)
l Export receiver data to CSV format for inspection and manipulation in a program of your choice
The HR2 Receiver
The new, feature-rich HR2 (High Residence)receiver is an excellent choice for tracking many fish with higher accuracy than ever before using our smallest fish tags (V4, V5, and V9). The High Residence telemetry system was designed specifically to allow researchers to monitor or position many tagged animals with sub-meter accuracy. The HR2 receiver detects both PPM1(VEMCO's traditional coding system) and HR2(VEMCO's new High Residence coding system) transmissions from 180 kHz tags (transmitters).

1
Pulse Position Modulation (PPM) is a signal modulation technique that allows computers to share data by measuring the time each
data packet takes to reach the computer (transmitter to receiver).
2
High Residence (HR) is a VEMCO technology that allows for the reliable detection of hundreds of animals in a particular location at one time. Each transmitter carries a unique ID and can be programmed to transmit as quickly as once per second while keeping transmission collision rates to a minimum. HR transmitters can also be programmed with traditional PPM coding, and are thus compatible with both VEMCO HR2 receivers and 180 kHz VR2Ws.

HR2 Receiver User Guide

1.1 HR2 Receiver - Overview

The 180kHz HR2 Receiver is a submersible and autonomous or cabled receiver capable of decoding two different methods of transmitting IDs to satisfy different study design objectives. To remain compatible with VR2W receivers, the HR2 can detect tags transmitting our traditional PPM (pulse position modulation) and the new HR transmissions at the same time.
This means that you can use the HR2 with your existing VR2W-180 receivers in collaboration with other researchers in a large scale monitoring network or you can use HR2 receivers to set up a small scale positioning experiment. HR2s are currently being used to monitor and position migrating salmon in rivers, eels migrating to sea and non­native predator impacts on native fish.
Common uses for HR2 receivers
l Monitoring hundreds of fish moving quickly through acoustic gates
l Ultra-fine scale positioning for behavioural studies including fish passage,
spawning, and habitat selection
l High residence studies of hundreds of tagged animals
l Frequent and precise positioning of fish (i.e. sub-meter every second depending on
tag transmission rate)
l Monitoring migration survival
l Monitoring predator and prey behavior
Advantages
l The HR system provides highest possible resolution data (high spatial resolution for
positioning studies (~1m) and frequent animal positions (of the order of seconds)
l Autonomously deployed HR receivers can easily be moved to different areas
l Add as many tagged animals to the system as desired without affecting the frequency with which
positions are calculated
l Connect a cable to any receiver at any time to view detections in real time
l Compatible with VR2W-180 kHz receivers; detects two transmission systems simultaneously
(PPM & HR) to support high residence and long term monitoring studies
l Communicate diagnostic information (for example, receiver health, tilt, ambient noise level,
temperature, detection counts) to a surface VR100-200 through a transponding link
l Detects VEMCO’s family of high frequency tags (weighing 0.42g to 2.0g) making it ideal for
juvenile to large fish (20g+ weight)
Transponding
Rather than employing a diver to check your receivers, you can communicate with the receivers remotely from the surface to learn about their status (tilt, battery level, number of detections, and number of detections of IDs of interest). Having transponding capability adds tremendous value in numerous scenarios including VPS studies, range testing and knowing if fish have passed a receiver gate.
The HR2 communicates to the surface through our VR100-200 active tracking receiver. It is compatible with all VR100-200 models sold since January 2013.

1.2 HR2 Case and Parts

The HR2 receiver is housed in a corrosion resistant black plastic high pressure case. The case consists of two main parts:
l the end cap which houses the hydrophone and internal battery tray that holds the battery, and
l an outer cylinder that is unscrewed to install the lithium or alkaline battery pack.
The HR2 is shipped closed, with the battery installed and connected. It is shipped with a dummy plug connected to the communications port on the bottom of the receiver.
The only time the case needs to be opened is when replacing the battery or preparing the unit for long-
term storage (6 months or more).
IMPORTANT: The receiver is NOT ready to record data yet, as it is shipped in Suspend Mode.
Your first task is to connect it to a computer and the Fathom software and place it in Record Mode. For more information, see "Getting Started", on page15.
Figure 1-1: HR2 Receiver with external Dummy Plug installed
WARNING: The HR2 pressure case and seal have a maximum static depth rating of 300 meters (440 psi). 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 and water may enter the HR2 case.
If the O-rings or their mating surfaces are dirty or damaged, then water may also enter the case. If you are suspicious that water has entered the case, then follow the suggestions in "I Think The Case
Might Be Pressurized", on page176.

l the main cable (black) which connects to the receiver, and
l the interface box with USB cable (white) that connects to the computer.
Figure 1-4: VEMCO High Speed Offload Cable

1.3.1 Communication Cable Information

Make note of the following capabilities and limitations in the use of the HSOCcable:
l The HSOC is powered by a PC USB port or USB bus that can provide 500 milliamps. It can
offload data from an HR2 receiver that has an expired internal battery or if the battery has been removed.
l The HSOC should not be used with a USB bus that does not have 500 mA available (e.g. USB
bus not powered externally).
l If the internal battery is dead/missing, and you plug in the HSOC, you’ll have to wait for the HR2
receiver to boot before you can "talk" to it.
l The HSOC supports data transfer rates up to 12 million bits per second (12Mbps). Speed is
reduced if used with cables greater than 10m in length.

HR2 Receiver User Guide

1.4 Operation Modes

The HR2 receiver has two operating modes: Suspend and Record Mode.

1.4.1 Suspend Mode

Suspend Mode is a low power state used when the HR2 is being shipped or in storage for an extended period of time. When in Suspend Mode, the receiver will not detect transmitters.
NOTE:In Suspend Mode, the status LED does not flash.
For details on how to place the HR2 in Suspend mode using the Fathom software, see "Suspend Mode
(not recording)", on page73.
CAUTION: The HR2 is shipped in Suspend mode, with the internal battery connected. Always put the receiver in Record mode (start a study) before deployment.

1.4.2 Record Mode

During testing and deployment, using the Record Mode allows the receiver to detect transmitters and record tag information. Because the receiver is shipped and stored in Suspend Mode, it must be put in Record Mode before it can detect tags.
NOTE: In Record Mode, the receiver Status LED will flash 2 quick red flashes every 5 seconds.
For information about entering Record Mode using Fathom, see "Record Mode", on page66.

2.6 Establishing Communication

To establish communication with an HR2 receiver from within the Fathom software, perform the following steps.
Step 1 - Fathom attempts to detect connected receivers
After launching Fathom, the Receiver Communications window appears.
Available COM ports are automatically displayed.
When a VEMCO cable is detected, Fathom displays it as a COM port and automatically initiates a scan for devices connected to the cable.
While Fathom is scanning for receivers, the
Scan for Devices button is temporarily
unavailable for use. The device scan may take up to 6 seconds.
Step 2 - When a receiver is detected
When an HR2 receiver is detected, it is displayed as shown here.
24
Step 3 - If no receiver is detected
When no receiver is detected, a receiver icon will not be displayed and you must manually initiate the connection.
l Click the Scan for Devices button to
rescan for receivers (top left).
l If you are using a COM port for
connection on the computer, click a COM port and select HR2 from the box that pops up, to establish receiver communication on that port.
If you are not sure which COM port the receiver cable is connected to, unplug the cable and watch which COM port disappears from the COM Ports display. Plug the cable back in and attempt to connect to the receiver using the identified COM port.
2.6 Establishing Communication
l If you are unable to connect to the
receiver, disconnect the cable from the computer, then the receiver, then reconnect to receiver and computer and try this again.
If you still are unable to connect to the receiver, consult our Customer Service
website.
Step 4 - Displaying additional information
Additional information about the receiver can be displayed by hovering over the receiver’s icon with the mouse. Available information includes the Cable ID number, and the Communication Port used.
25

2.8 Testing the Receiver

2.8 Testing the Receiver
Before deploying an HR2 Receiver, we recommend that you conduct in-air tests with one or more tags to:
1. Familiarize yourself with operating Fathom software and HR2 receivers. The air test will allow you to go through the process of connecting to an HR2, activating a tag and using Fathom to conduct a new study and upload data, etc.
2. Test your tags and receivers before implanting tags into your fish. If any problems arise we would like to know beforehand, rather than on the day you are conducting surgery and releasing fish or deploying receivers.
IMPORTANT: Handle 180 kHz tags with care. Do not squeeze the tags. Avoid using metal forceps.
Do not shock the tags with instruments that carry static charge.
If you drop a tag on a hard surface you should test the tag to see if it still functions and you should
record it in your notebook (ID code & Serial Number). Our tags have a medically inert coating of Parylene. If you scratch the tag you might damage the coating.
Tests can, and should, be done in both air (see "In-Air Test", below), and water (see "In-Water Test",
on the next page).

2.8.1 In-Air Test

The HR2 can detect coded tags and communicate with a VR100-200 in air but does so at a much reduced range compared to its range capabilities when it is in water.
IMPORTANT: Perform in-air tests away from electrical noise sources such as motors, PC screens, or fluorescent lights.
To perform an in-air test
Acoustic high frequency signals do not transmit well through air. To conduct the test the tag or tags need to be touching or very close to the HR2 hydrophone (millimeters, see image).
1. Connect receiver to computer (see "Connecting an HR2 Receiver to a
computer", on page18).
2. Launch Fathom software (see "Launch Fathom", on page20).
3. Establish communication with receiver (see "Establishing Communication",
on page24).
4. Ensure receiver's built-in transmitter is ON (see "HR2 Transmitter Tab", on page44).
5. Start a study (see "Starting a Study", on page67).
6. Select the Live Detections tab.
7. Activate your 180 kHz tag(s) and place it less than 2.5 cm (1”) away from the HR2 hydrophone (tip) so the side of the tag is facing the side of the hydrophone.
29
HR2 Receiver User Guide
8. Observe the tag transmissions in the Live Detection Monitor display. You should see either HR (A170-1802-XXXX) or PPM (A180-1702-XXXX) or both transmission types.
You should also see detections of the receiver's on-board transmitter, transmitting as programmed in Step4. You can also watch the LED flash patterns as the tag is detected and the data are stored in memory:
a. When activated, a transmitter transmits 10 IDs quickly over approx. 10-15 seconds
and then the tag enters its programming cycle that was setup between you and VEMCO at the date of order.
b. Each quick red flash of the Status Light is a received PPM ping.
c. A long, bright red flash is a stored PPM detection.
d. Blue flashes indicate HR detections.
e. During this test you can also confirm that the on-board Sync tag is transmitting as
programmed in Fathom.
f. If the flash patterns are different, compare it to the Status Light Flashes chart
(see "Status Light Flashes", on page165).
9. Take a quick look at the number of detections and pings received listed in the receiver Status information on the Status tab, or select the Live Detections or Live Tiles tab to see live ping information.
10. Offload the data that was collected during the test, creating a data file (see
"Offloading Data", on page70).
11. Export the offloaded data to a CSV file (see "Exporting Data", on page95) and view the data to verify that the data was stored and retrieved without problems.
12. If you do not plan to deploy your receivers right away (within a day or two), place the receiver in Suspend Mode (see "Suspend Mode (not recording)", on page73). To start recording at deployment time, bring the receiver out of Suspend Mode by starting a new study (see "Starting a Study", on page67).
This simple test confirms that the receiver is working properly, a tag is decoded properly, and it confirms that your tag is functioning as intended.

2.8.2 In-Water Test

Tests performed in water are almost identical to the in-air test. The only difference is that the equipment does not need to be as close in water as it does in air.
For example, the tag could be positioned 5 meters from the receiver for testing purposes. In-water tests are often performed to establish an ideal range for the HR2 receivers in the environment in which they are moored. Details of conducting a Range Test are found at our Customer website.
30
2.8 Testing the Receiver
To perform an in-water test
You can do this test in a bucket or tank or in a larger body of water.
NOTE: Water testing can a bit trickier than air testing because in small spaces the signals might distort due to reflections and reverberation. In this case you might need to try and move the tags and receivers to different locations. If conducting the test in a small bucket try moving the tags around. Place your tags in a mesh bag or hold the tag underwater with your hands. If in a large body of water be careful not to drop your tags. You might need scuba to recover the tags!
Sometimes you might need to try different configurations to ensure that you can successfully decode the tag or tags. Stay away from hard surfaces, concrete, rocks, etc., when testing.

3.3 Live Tiles Tab

3.3 Live Tiles Tab
The Live Tiles Tab displays summary data (as tiles) about incoming detections of each transmitter, in real time. It allows quick and easy visualization of the detection frequency of test tags or animal tags within range of the connected receiver, as well as the detection frequency of neighbouring receivers' synctags. This feature is particularly useful when range testing or testing a VPS setup.
Figure 3-4: Live Tiles Tab

3.3.1 Understanding The Live Tiles Display

The Live Tiles display is divided into two sections: one for HR detections and one for PPM detections.
NOTE:You can select which Quality level of detections to display (see "Live
Tiles and Live Detection Filter Options", on the previous page).
Figure 3-5: Sample Tile information
The information displayed on each tile is as follows:
l First line: Transmitter ID.
l Second line, before the comma: The total number of detections of the ID since connecting to the
receiver, or since clearing the Live Tile display.
l Second line, after the comma: The average time between detections, in seconds. This number
can be used along with the transmitter delay to calculate a rough estimate of the percentage of transmissions that are being detected.
l Third line: The amount of time (in hh:mm:ss) since the last detection of the ID.
39
Tile colour example Rule description
Grey - First/initial detection (HR detection example), needs a
second detection to be validated.
A tile will remain grey until a second detection of the same ID occurs. The second detection must be logged within the time threshold specified under Tile Settings (see "Live Tiles Display Settings",
below), or the detection will be considered false and the tile will
disappear.
Green - Second detection (HR detection example), detection is val­idated.
If a second detection of the ID does occur within the specified time threshold, the tile will turn green to indicate that detections of that ID are coming in at the expected rate.
Once a tile has turned green, it will remain in the display window until the tile is closed (by clicking on the red "X" in the top right corner of the tile) or the Clear Tiles button is clicked.
A tile will remain green as long as detections of that ID continue to come in within the time threshold specified under Tile Settings.
Orange - Detection (PPM detection example) exceeding the time threshold limit.
If the time threshold is reached without a new detection coming in, the tile will turn orange to indicate that the detection rate of the ID is lower than expected.
Red - Subsequent detections (PPM detection example) exceeding the time threshold limit.
If the detection frequency continues to miss the time threshold, the tile will turn red.
HR2 Receiver User Guide
Upon first detection of a given ID, a grey tile will appear in the appropriate section (HR or PPM).
The tiles are automatically colour-coded, according to the following set of rules:

3.3.2 Live Tiles Display Settings

The Live Tiles display can be filtered to limit clutter on the screen in situations where many tags are within detection range at once. You may therefore want to focus exclusively on a subset of tags.
The time thresholds of the display can also be configured to suit the programming of your particular tags.
To view only HR detections or only PPM detections, collapse the section that you are not interested in by clicking on the up/down arrow to the left of the HR or PPM section header.

Transmitter Profile options
Click the down arrow to display the options, and then select one for the receiver to use.
NOTE: Sync Tag is the default transmit profile and is recommended at all times when not conducting range testing.
Sync Tag (HR 25-35s, PPM 270-330s)
This setting transmits with a random delay between 25 and 35 seconds for HR coding, and 270 and 330 seconds for PPM coding.
Use the Sync Tag setting if you are preparing your receivers for a longer-term deployment.
l If you are conducting a positioning (VPS) study, Sync Tag detections will be used to
synchronize your receivers' clocks and facilitate accurate position calculation.
l If you are not conducting a VPS study, use the Sync Tag setting to have your transmitter
act as a control or sentinel tag. In this case, you may use detections of the transmitter on neighbouring receivers as a means of monitoring ongoing acoustic conditions.
45
HR2 Receiver User Guide
Range Test Random (HR 4-6s, PPM 25-35s)
This setting transmits with a random delay between 4 and 6 seconds for HR coding, and 25 and 35 seconds for PPM coding.
Use this setting when performing range tests using more than one transmitter, or when using a single transmitter in areas where tagged animals are present. The random delay setting will help to reduce the likelihood of transmission collisions in these cases.
Range Test Fixed (HR 5-5s, PPM 30-30s)
This setting transmits with a fixed delay of 5 seconds for HR coding and 30 seconds for PPM coding.
Use this setting only when performing range tests using a single transmitter, and when there are no tagged animals known to be in the area. The fixed delay setting means that transmission collisions are likely to occur if other transmitters are within range of your receivers at the same time.
IMPORTANT: Range Test Random and Range Test Fixed transmit profiles should only be used for purposes of short term testing. For long term deployment, remember to change the transmit profile back to the default (sync tag) setting.

Updating the Firmware (manually)
Firmware (FW) is a program that is stored permanently in a device, such as an HR2 receiver. It is not to be confused with Fathom, the PC software used to communicate with the receiver. Firmware updates are rare and will occur to either complete a hardware change or occasionally for a significant addition to functionality.
NOTE: HR2 receiver firmware can only be updated when connected to Fathom.
IMPORTANT: Ensure that all data are offloaded from the receiver before performing a firmware
update.
Normally, you would perform an firmware update after receiving an automatic firmware update notification (see "Automatic Firmware Updates and Notifications", on page168). If you decided to perform the update later (and canceled the operation), you would be using this procedure to complete the update.
55

Deploying an HR2 Receiver

How an HR2 receiver 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 HR2 receivers are explained here. The common method for attaching a HR2 to a mooring line is also given.

5.1 Case External Dimensions

The HR2 receiver's case dimensions can be useful when designing a mooring plan or mooring equipment. The dimensions, in inches, are shown in the drawings below.
Figure 5-1: HR2 Case Dimensions
76

5.2 Deployment Facts and Tips

5.2 Deployment Facts and Tips
Before deployment, read these carefully to maximize the performance of your HR2 receivers.

5.2.1 Mooring

HR2 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 HR2 should be positioned above the floor such that it has an unobstructed “view” of tagged animals within their expected acoustic range. Ensure the HR2’s hydrophone is unblocked (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 HR2 receiver in a vertical position. Always mount the HR2 with the hydrophone pointing up to the surface, for better acoustic communication with the VR100.
CAUTION: The hydrophone must be kept free of mooring lines and obstructions. Objects around the hydrophone will adversely affect the detection range of the HR2 receiver.

5.2.2 Spacing

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 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 every receiver location then you should strive for 100% detection probability. Typical spacing is usually between 100 and 300 meters.
REFERENCE: See the Gate Design tutorial on our website.
Receiver spacing guidelines for VPS studies differ from gate studies because complete overlap of detection ranges is required for successful fine-scale positioning. For more information on estimating appropriate receiver spacing for your study, please refer to the VEMCO Range Test Software Manual, from our website, and make sure to conduct tests as described in "Testing the Receiver", on
page29.

5.2.3 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 HR2 receiver. It can be used to cover the receiver body (do NOT cover the hydrophone) and does not leave a glue residue when removed. Another option is to use an antifouling paint, such as Interlux Micron CSC.
NOTE:Keep the hydrophone uncovered to prevent acoustic dampening.
CAUTION: The Status Light is also a pressure relief valve. Never cover the Status Light/Release Valve. The release valve must be able to pop open if needed and must not be blocked by tape or
paint.
77
HR2 Receiver User Guide

5.3 Mooring Line Attachment

The common method used to attach a HR2 receiver to a mooring line is to use five cable ties (zip tie or tie-wrap) with the following characteristics:
l Non-reusable lashing cable ties
l 388 mm (15.25") long
l 7.5 mm (0.3") wide
l UV protected
l 120 lbs tensile strength
l mooring line
l 3/8" minimum diameter nylon rope
A set of five cable ties is shipped with each new HR2 receiver and more may be purchased from VEMCO (product number HWE 507450).
Follow the instructions listed below to attach the HR2 receiver to the rope used as the mooring line.
Step 1 - Attach locations
Identify the location on the rope where the bottom of the HR2 receiver will be attached.
(VR2Tx example shown)
Step 2 - Twist rope
Twist the rope so the strands of the rope separate from each other and an opening in the rope is seen. This is referred to as opening the “warp in the rope”.
Step 3 - Slide cable tie through
Slide one of the cable ties through the center of the rope and the Attachment Hole.
(VR2Tx example shown)
78
Step 4 - Latch and tighten
Latch and tighten the cable tie so the head of the cable tie is next to the rope.
(VR2Tx example shown)
Step 5 - Slide, latch and tighten
Open the warp in the rope again and slide another cable tie through rope so it lines up with the bottom half of the lower groove around the body of the HR2. Tighten the cable tie so the tie’s head is next to the rope.
(VR2Tx example shown)
5.3 Mooring Line Attachment
Step 6 - Slide, latch and tighten
Wrap a third cable tie around the HR2 receiver and the rope so the cable tie occupies the top half of the lower groove in the HR2 body. The bottom half of the groove is already occupied by the cable tie from Step 5 Latch the cable tie so the head of the cable tie is over the rope.
(VR2Tx example shown)
Step 7 - Slide, latch and tighten
Open the warp in the rope next to the groove closest to the hydrophone and slide another cable tie through rope so it lines up with the top half of that groove. Tighten the cable tie so the tie’s head is next to the rope.
79
HR2 Receiver User Guide
Step 8 - Slide, latch and tighten
Wrap a fifth cable tie around the HR2 receiver and the rope so the cable tie occupies the bottom half of the groove used in Step 7. Latch the cable tie so the head of the cable tie is over the rope.
Step 9 - Trim off excess
Trim the cable ties so there is no excess cable tie material and no sharp edges.
Figure 5-2: Sample mooring line attachment (VR2Txshown)
WARNING: Cut the cable ties when removing a HR2 from the mooring line. DO NOT re-use cable
ties. Use only new cable ties when deploying a HR2 receiver.

5.4 External Cable

5.4 External Cable
The HR2 Receiver uses an external cable to connect to other devices. VEMCO has successfully used cable with the following specifications:
l 2 Twisted Pair - 18 AWG stranded tinned copper (STC); 0.070” PP insulated; Individual foil
shield, Drain (Twisted Pair coloring scheme: Pair 1: Green/White; Pair 2: Red/Black)
l Overall Copper Braided Shield (80% coverage)
l Black polyurethane jacket to an overall outer diameter of approximately 0.290”
l Two jacketed Kevlar 49 strength members with breaking strength of 350 lbs each
l UV stabilized
l SubConn MCIL8F connector on HR2 end
There could be variations on these cable specifications based on individual customer needs. VEMCO should be consulted when designing specific cabling solutions.

Diagnostic Information (HR2, VR2Tx, VR2AR, and VR4-UWM receivers only)
l (A)Noise Samples (dB or mV) - Noise values are plotted relative to the primary y-axis. You can
access the noise level at any time along the series by moving the cursor over the location on the plot where you want to see details. Date and Time are also displayed. Noise readings are not available for VR4-UWM receivers.
l (B)Tilt and Temperature - Tilt and temperature values are plotted relative to the secondary y-
axis. Select which value you would like to display using the Tilt, Temperature, or None options at the top right of the plot. You can access tilt or temperature values at any time along the series by moving the cursor over the location on the plot where you want to see details. This information appears along with the Noise Sample and Date and Time described above. Temperature is not available for VR4-UWM receivers.
l (C)Resizable - This section is resizable in height internally, using click and drag up or down
action with the resizing grab handle, between the graphs.

6.1.4 Data Visualizer Filter Options

The Data Visualizer Filter Options provide choices for filtering detections based on the source of the detection (HR2 VR2Tx, and VR2AR receivers only). You may view self-detections (detections of a receiver’s own built-in transmitter) only, external detections (all detections except those of the receiver’s own built-in transmitter) only, or detections from both sources. The default option is both sources.
To select a filter option
At the right of the Data Visualizer window, click the current filter option. The Filter Options box appears, and displays the available options. Select the source to set the options and return to the Data Visualizer window.

6.1.5 Using The Range Selector Tool

The Range Selector tool allows you to select a range of dates/time to view in the graphs in the Selection section. A shorter range provides more detail, a longer range provides a longer overview.
