NMEA0183 Wi-Fi Gateway
Bringing Instrument data into your apps
Get GPS, AIS and other data from your instruments into your apps and software, and send data out to your chart plotter or autopilot.
The device sends and receives NMEA0183 data, the industry standard for many years, and still output by most newer instruments that use NMEA2000. All valid NMEA0183 sentences are supported. It will run at speeds from 4800bps (standard NMEA) to 38400bps (for AIS). The NMEA port is fully opto-isolated in both directions, and will tolerate inadvertent connections to the boat’s power supply.
Supports simultaneous UDP and TCP connections. For a simple installation the device can act as a wireless Access Point (AP) that you connect your devices to, or if you have a router on board the device can be a client to the router. When acting as an AP, it also acts as a DHCP Server for easy setup of your phone or tablet.
We have designed the device for maximum compatibility with your apps, with both TCP and UDP support, and the ability to change IP addresses and port numbers to match your app’s needs. This means that it will work with virtually all apps that use NMEA0183 over Wi-Fi.
Designed for boats in mind, it will run off a 12V or 24V DC supply, and tolerate voltages from 7 to 32V. Power consumption is just 70mA. It has reverse polarity protection, and an internal self-resetting fuse.
Standard WEP/WPA/WPA2 Wi-Fi security is used to keep your network secure, and the configuration pages are also password protected.
LEDs on the front panel tell you exactly what is going on. For configuration, just use the QR code to open your web browser, or type in the IP address, and you are led through the setup and configuration.
