B620WS
Our most sophisticated 2W AIS class B transceiver with integrated Wi-Fi and antenna splitter
SKU Part Number：AMEC-B620WS-010
Overview
Superior Performance Guaranteed
Powered by AMEC’s 3rd-gen AIS engine, the B620 series unleashes superlative AIS performance, best-in-class receiving sensitivity of -111dBm and world’s lowest power consumption.
Integrated 802.11 b/g/n Wi-Fi
Built-in Wi-Fi supporting Client Mode and Access Point Mode to make your phone/pad a mobile charting device.
Integrated zero insertion loss antenna splitter
The built-in antenna splitter allows a single VHF antenna to be shared by both the AIS and VHF radio. The high-performance antenna splitter has zero insertion loss on reception path and ultra low loss on transmission path.
Interconnection Intelligence
B620WS incorporates NMEA 2000 to enable quick installation and interoperability with other bridge systems. Its dual NMEA 0183 ensures easy integration with legacy board devices. PC/Mac based navigation program can be connected to B620 through its USB port.
Built to Last
Robust from electrical to mechanical design, built to endure for years to come.
