NMEA Wifi Bridge

NMEA Wifi Bridge – Gateway – Transponder

UNIMAX NW-22 is a smart NMEA to Wifi bridge. It sends every NMEA message it receives to the WiFi devices it is connected to. You can see marine navigation information such as GPS, AIS in software applications. Compatible with many marine sofware applications.

It can simply be connected to many wireless devices such as PC and smartphone. Supports TCP and UDP protocols. NW-22 creates its own wifi network. You can connect to the device directly or connect it to another network.

NMEA input support 4800, 9600, 38400, 115200 baud rates. NMEA output transmits data at a constant rate (115200bps).

Also supports ethernet connection optionally.


To change the wifi bridge’s settings, you need any wifi enabled device with any web browser. IP address port number, TCP, UDP, SSID options can be easily setup via the web interface.
