COASTAL ACOUSTIC TRANSPONDER FEATURES • Easy maintenance • Small lightweight package • Full transponder capability • 2 years on alkaline batteries • Secure command coding • Tilt / no tilt indications The Coastal Acoustic Transponder (CAT) is ideal for deployments in coastal environments. The acoustic command structure is the same as that used in all of our underwater acoustic releases and transponders and is unsurpassed in multi-path environments. The CAT has been designed for use as an underwater instrument location and positioning aid. They have applications as part of the recovery system on oceanographic moorings and platforms. The precision, high output power and commandable CAT - end cap with zinc anode transponder feature make these instruments ideal for use with positioning systems in difficult acoustic environments. The CAT utilizes EdgeTech’s field proven Binary Acoustic Command System (BACS) code structure. The BACS coding structure provides 12,000 possible secure command codes. Each transponder is factory programmed with its own unique command set which includes transponder ENABLE, DISABLE. Whenever the instrument receives a command it responds with a status reply message which indicates the orientation of the instrument (tilted or not tilted). The transponder function can be turned on or off with the ENABLE and DISABLE commands. When disabled the transponder will not reply when interrogated. This ensures that the unit will not interfere with nearby instruments and that no battery energy is wasted replying to interrogate signals meant for other systems.
