SI-TEX Next-Gen AIS Modules

SI-TEX Marine Electronics has added 3 new AIS Modules to its line-up for 2012. The new Metadata AIS Module line includes a Dual Channel AIS Receiver, a Class B AIS Transceiver, and an AIS Antenna Splitter. All are housed in a compact (5.5” x 3.9” x 1.9”) module that is IPx7 waterproof-rated, allowing them to be mounted virtually anywhere on a boat.

The Metadata Dual Channel AIS Receiver module features the next-generation Rmax AIS technology, with fast processing to maximize reception range and ensure that all incoming AIS messages are received and fully decoded in real time. This overcomes performance issues experienced with earlier AIS systems in real-world marine situations. The advantages of Rmax technology will become even more important as the number of AIS-equipped vessels increases in the future. Designed for plug-and-play integration with chartplotters, radars, onboard PCs and other marine electronics, the Metadata Dual Channel AIS Receiver has built-in NMEA 0183 and NMEA 2000 interfaces, as well as a USB interface that can be used to power the device.

The Metadata AIS family also includes a Class B AIS Transceiver for sending and receiving AIS signals. It features an Rmax Class B engine that provides maximum range and efficient real-time AIS message processing for all message types. The transceiver features an internal 50-channel GPS “smart antenna”, eliminating the need for an external GPS antenna in many installations.

Rounding out the line is the Metadata AIS Zero Loss Antenna Splitter, which allows for the full use of VHF communications and AIS send/receive with a single antenna. The splitter was developed specifically for use with Class B AIS transceivers, providing optimum AIS and VHF radio performance in all situations. Built-in safety features such as Clear Call Routing (CCR) ensure VHF radio emergency call priority—and continued full-performance operation, even if the vessel’s power should fail. The Zero Loss Antenna Splitter is designed for easy integration with other marine electronics, and can be used to receive FM broadcasts.
