GAMP 183

An advanced Wi-Fi Multiplexer able to handle the NMEA0183 protocol and to transmit data via wired directly to your mobile devices

Connect the onboard instruments all together, AIS, GPS, chartplotter, automatic pilot, and visualize the useful data in real time, on smartphones, tablets, pc and esa Watch.


Connect together all the onboard instruments with the NMEA0183 protocol, visualize the data on the mobile devices or on the wired instruments (displays, chartplotters, PCs).

With onboard Wi-Fi signal is it possible to use all your favorite navigation software on your devices.

GAMP is a router multiplexer access point NMEA: it is compatible with the most common nautical apps for Smartphone and tablet. The GAMP NMEA0183 can record the navigation data of your sailing sessions giving you the possibility to analyze them later.

GAMP0183 supports AIS and NMEA signals up to 115200 baud. 
The multiplexer’s configuration and management software enables users to select wanted sentences, manages gates priority, defines various baud rates and selects the perfect filter for sentences, for a complete versatility and calibration of the on-board instrumentation network. Connect through Wi-Fi up to 4 devices simultaneously.
