OneRain Announces Release of Contrail Field Decoder Software Version 1.4

LONGMONT, COLORADO, December 18, 2017 – OneRain Incorporated today announced a new release of software for its Field Decoder Solutions. Contrail® Field Decoder software and associated StormLink® IQ Receiver and StormLink RF Receiver products are used by flood warning managers and field maintenance personnel for on-site trouble-shooting, radio frequency verification, and performance testing of their hydrological monitoring networks.

Optimum network design and the peak performance of gauging stations are critical for the reliable delivery of data in real time flood-warning monitoring systems. OneRain’s Field Decoder Solutions enable best field practices and testing techniques with the ability to receive and decode radio communication signals at a site directly into a laptop. Field staff can readily test and verify that gauge sites and configurations are correct.

This latest version of Contrail Field Decoder Software includes several performance improvements and user interface enhancements:

  • A new “Settings” page which configures frequency and other settings
  • Collector connections! A one-click configuration to temporarily stream ALERT2 over a network to Contrail or other loggers for testing
  • An overhaul to the “Readings” Tab
  • Performance improvements everywhere, especially when viewing many messages at once
  • Disabled debug logging; decreases disk space usage

Announcing OneRain ALERT/ALERT2 Field Decoder Solutions for Hydrologic Networks

In the News May 2016: OneRain’s new ALERT/ALERT2 Field Decoder Solutions created quite a stir when introduced at the recent 2016 ALERT Users Group Conference—the year’s largest gathering of flood warning professionals in the U.S. OneRain’s StormLink™ IQ Receiver has the capability to receive and decode signals from 25 MHz to 1750 MHz, which covers the hydrologic radio frequency bands.

For those operating hydrology networks, OneRain’s Field Decoder Solutions allow in-the-field analyses of gauge data messages for trouble-shooting, verification, and optimizing gauge network performance for ALERT/ALERT2 flood early warning systems and field instrumentation maintenance operations.

The StormLink IQ Receiver is a simple low cost mobile solution for receiving and decoding field sites. The small USB-type device plugs into a laptop and, with OneRain’s Contrail® Field Decoder Software interface, users can easily change between frequencies and receive and decode ALERT2™ radio signals directly on their laptop.

StormLink® Field IQ Receiver and Software

The company also announced their rugged StormLink RF Receiver—a radio-based ALERT2 receiver with controls that allow users to switch frequencies and receive/decode either ALERT or ALERT2 messages. The StormLink RF Receiver will be upgradable to a 2-way transceiver which will allow it to transmit and receive ALERT or ALERT2 for testing repeaters and two-way sites such as those used by flasher or siren systems.

“Feedback has been very positive”, says James Logan, OneRain’s CEO. “OneRain has made a lot of progress developing and implementing the support for ALERT and ALERT2 with this radio technology. We plan on adding the capability to simultaneously decode multiple frequencies and multiple protocols, so an agency that is going through the transition from ALERT to ALERT2 can see all of their messages as they go through the network.”

OneRain’s Field Decoder Solutions are available in bundled software and hardware packages.
