Introduction
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
lInitializing, configuring and uploading data from VEMCO HR2 Receivers
lViewing live detection data in real time (great for testing and troubleshooting)
lIntegrated easy-to-search help (for both the Fathom software and the HR2 Receiver)
lExport 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).

1Pulse 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).
2High 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.
