| ACOUSTIC MODEMS |
|
Teledyne Benthos underwater acoustic modems are used in worldwide subsea applications to transmit data wirelessly through the water. They are the only modems available in a combined modem/acoustic release configuration. Reduce expensive underwater cabling by making any subsea sensor a wireless sensor for shallow or deep water applications. Customer Integrated Electronics (CIE) available.
Modem applications include remote monitoring of oceanographic sensors, control of wellhead and pipeline valves, control of autonomous underwater vehicles (AUVs), and subsea networking. The ATM series acoustic telemetry modems are the most advanced, multi-path, noise tolerant, and cost efficient ever available. They are designed to meet both high data rate requirements and higher reliability, lower data rate requirements.

| ATM-900 Series Modems |
|
The Teledyne Benthos ATM-900 Series Acoustic Telemetry Modems are a major enhancement to previous modem lines offered. The new ATM-900 Series provides a long list of special purpose, flexible extensions supporting multiple capabilities beyond "just" underwater communications. These capabilities range from high capacity data logging, through updated data storage and user command line interfaces to real-time clock integration. Each surface unit can operate using cables from 2m to 200m with a mating transducer for each cable. Both directional and omnidirectional transducers are available.
