Pacific Crest Introduces New Advanced Data Link for Remote Communications

HOUSTON – Pacific Crest, a Trimble company, today introduced the new ADL Sentry, a UHF radio for remote communications. It is an advanced, high-speed, data radio modem built to survive the demanding environments of remote sensing and environmental monitoring. The ADL Sentry joins the growing Advanced Data Link (ADL) product line that includes the ADL Foundation, a transceiver OEM modem board; the ADL RXO, a receive-only OEM board; and the ADL Vantage, a 4-Watt programmable UHF radio for survey applications.

The announcement was made today at the Offshore Technology Conference 2010.

“With the ADL Sentry, we have added a key component to our innovative line of digital radios that delivers new levels of quality, reliability and flexibility for data communications,” said Dale Hermann, director of marketing and sales for Pacific Crest. “Interoperability with existing equipment and greater functionality will allow our customers to rapidly and cost-effectively deploy the ADL Sentry into their applications.”

The ADL Sentry is a sophisticated 0.1-4.0 Watt radio modem that utilizes Pacific Crest’s next generation ADL technology. It is backward compatible with existing Pacific Crest, Trimble and other products.  Using metal construction, the ADL Sentry resists impacts and electromagnetic interference.  With an IP67 rating, it is completely sealed against dust and can survive immersion in up to a meter of water for approximately 30 minutes to withstand harsh weather and demanding outdoor conditions. The ADL Sentry is ideal for remote sensing, machine control, and environmental monitoring applications.

The ADL Sentry is available in two 40 MHz frequency bands (390-430 and 430-470 MHz) to cover the entire commercial UHF band without sacrificing radio performance. It also allows the user to select from available channel tables in either 12.5 or 25 kHz channel bandwidth. With its high over-the-air link rate and next generation RF design, the ADL Sentry offers higher bit rates to easily handle large data packets and configuration control commands on the same channel.

The ADL Sentry and a full range of antenna, power, mounting and cabling accessories are currently available through Pacific Crest’s international network of authorized dealers.
