Convert Elfin EW10 NMEA Navigation Data to Wireless Signal Effortlessly

Pretty neat, huh?! Here's an effortless guide to turn your AIS equipment and other NMEA 0183 devices into a Wi-Fi marvel! Our budget-friendly Elfin EW10, similar to the HF2211, is the star of the show. This industrial converter lets you view real-time navigation info on your tablet or smartphone using apps like Navionics, OpenCPN, and more.

Let's dive in!

What's the Scoop with Elfin EW10?

Elfin EW10 is a Wi-Fi-to-serial module that turns UART (RS-232/TTL) serial data into Wi-Fi using TCP or UDP protocols. It works well with 3.3V to 5V logic levels, often used in marine electronics, and typically costs around €6-10.

Getting to Know NMEA 0183 Interface

NMEA 0183 is a serial protocol that usually runs at 4800 or 38400 baud (modern devices). It uses RS-422 differential signals, but many devices or adapters provide simple TTL serial. Be sure to examine your source device's output voltage and levels; the EW10 accepts TTL serial (3.3V or 5V).

What's on the Shopping List?

| Component | Purpose | Approximate Cost ||-----------|---------|------------------|| Elfin EW10 module | Serial to Wi-Fi conversion | ~€6-10 || Level shifter (optional) | If NMEA output is RS-422 or RS-232 | €1-3 || Power supply | 5V DC (USB) or 3.3V regulated | Existing or €1-2 || Wires/connectors | For serial wiring | Negligible |

Getting Down to Business: Wiring Setup

https://amzn.to/41NQ7KD On AliExpress:

  1. Power the Elfin EW10: Connect the 5V supply to module’s VCC, and GND to common ground.
  2. Connect NMEA 0183 TX to EW10 RX: Typically, NMEA 0183 output is labeled TX (transmit). Connect NMEA TX to EW10 RX pin.
  3. Connect EW10 TX to NMEA RX (optional): For bidirectional communication.
  4. Check voltage levels: Good practice to double-check voltage levels match. If differential, use a converter like MAX485 to TTL before EW10. If RS-232 (±12V), use a MAX232 chip to convert to TTL, not direct wiring.

Confirm the Elfin EW10 Module's Configuration

  1. Power on the EW10.
  2. Connect to its default Wi-Fi access point. The module creates an AP (e.g., SSID: ). Use a PC or smartphone to connect.
  3. Access configuration page: Open a browser at (default IP).
  4. Log In: Default credentials usually .
  5. Set Serial Parameters: Adjust baud rate, data bits, stop bits, and parity to match your NMEA source.
  6. Set Wi-Fi Mode: Choose between AP or Station mode (connect to existing Wi-Fi).
  7. Network Protocol: Select TCP Server mode or UDP broadcast, depending on your preference.
  8. Save and reboot the module.

Time to Connect Your Marine Device (like AMEC Camino, Em-Trak, or Matsutec HA-102)

  1. Learn the Wi-Fi NMEA data input method from your device's manual.
  2. Enter the IP address of the EW10 module and port number configured.
  3. Connect your device's Wi-Fi to the EW10 AP if the module is in AP mode, or to the same Wi-Fi network as EW10 if it's in Station mode.
  4. Configure the marine device to receive NMEA data from TCP or UDP, based on EW10 module setting.

Let's Test It Out!

  • Use a serial terminal on your PC to query the NMEA data stream.
  • Utilize smartphone apps (NMEA Wi-Fi tools) to connect to the module and verify NMEA sentences.
  • Check wiring for correct levels; no direct RS-232 to EW10.
  • Confirm baud rates and protocols match on both ends.

And voila! You've successfully transformed your NMEA 0183 signals into Wi-Fi. Enjoy navigating with your marine devices like never before!

Stay tuned for more tips on power supply, security, and potential firmware updates. Don't hesitate to ask for help with sourcing components or wiring diagrams tailored for your specific marine device. Happy sailing!
