The A035 is a sophisticated 4×4 NMEA 0183, WiFi and USB multiplexer  with Seatalk¹ converter ,with an integrated voyage data recorder (VDR). This NMEA 0183 multiplexer is capable of recording the messages transmitted from every input device. All messages are stored within an integrated SD card and can be accessed simply by using an SD card reader.

Through advanced filtering and routing, the A035 NMEA enables controlled routing of data to specific outputs, blocking of excess data and overflow reduction. The four NMEA 0183 inputs together with one Seatalk1 inputs can be routed to any of the four NMEA 0183 outputs, providing a highly customisable network.

Technical Specifications & Features

The multiplexer combines up to 4 NMEA 0183 inputs and one Seatalk1 device. All these messages are then sent to 4 NMEA 0183 outputs, USB and WiFi interface.
