The i320W Bidirectional NMEA Wi-Fi Interface is an upgraded version of the i300W. It provides a low cost method of setting up a wireless network on-board (802.11b/g/n), enabling you to stream your boat’s NMEA 0183 electronic data, such as AIS data, position, depth, wind, compass heading to your tablet, smartphone, PC, or Wi-Fi enabled chart-plotter.

Simple to set up, the i320W has 2 NMEA inputs which are multiplexed to a single high speed data output which transmits NMEA 0183 data over Wi-Fi and provides communication with any suitable NMEA devices. With 2 inputs, it can accept NMEA 0183 data at 4800 from
any GPS, Chartplotter or other navigation instruments or 38,400 baud input from any AIS receiver or transponder, so you only need one unit to collect and transmit all the navigation data of your boat via the wireless gateway.

For a vessel with a Chartplotter at the nav station, using the Comar i320W NMEA to Wi-Fi interface, the helmsman can view all the navigation data on deck via a suitable device, and for boats with the Chartplotter at the helm, it’s possible to check all the critical navigation data down below, making your boat’s data truly portable.

Compatible with all major charting applications, tested with:Navionics, Aqua Map, AFTrack, iSailor, NV Charts, OpenCPN
