The ATC-2000WF Serial to Wi-Fi Adapter provides a gateway between marine wired devices such as chart plotter networks, AIS devices and marine radios, and wireless devices such as tablets and PCs. One the wired side, this adapter can be connected to serial RS232 devices using the DB9 serial port or NMEA RS422 devices using the terminal block. On the wireless side, users can connect mobile devices such as iPads or PCs by joining the adapter's wireless network and configuring the marine app's network setup for UDP on port 2000. Data is sent as serial NMEA 0183 sentences. Wireless devices are automatically assigned an IP address when they join the units Wi-Fi network using an integrated DHCP server.
Milltech Marine pre-programs these gateways for use in marine environments and to make the setup as easy as possible for most marine scenarios. The adapter is configured to serve up to seven wireless device connections using UDP, meaning you can have up to 7 phones, tablets, PCs all connected and using the wireless marine data simultaneously. The ATC-2000WF unit is fully programmable and can be reconfigured to join an existing Wi-Fi network or use different baud rates. The default wired baud rate is 38400.
The unit can be powered using the included AC adapter or 9-24 volt DC onboard power.
Here are some examples for how this device can be used onboard to send marine NMEA data to multiple wireless devices such as iPads, smartphones or PCs:
  • Send chart plotter data including GPS, depth and wind to wireless devices. For example, connect the two NMEA output wires from your chart plotter to position 3 and 4 on the ATC-2000WF terminal block, set the chart plotter NMEA output to 38400 baud and you're done.
  • Send GPS, AIS and DSC data from a Standard Horizon GX2200 to wireless devices. In this case simply connect the GX2200 brown wire to terminal block position 3 and the gray wire to position 4, set the GX2200 NMEA baud rate to 38400 and enable GPS sentences and you'll then stream AIS, GPS and DSC NMEA sentences to your mobile device.
  • Send AIS and GPS data from an AIS transponder that does not support wireless (e.g. AMEC CAMINO-101AMEC CAMINO-108 or Vesper WatchMate 850) to wireless devices. For example, to connect a CAMINO-101, simply use the included serial cable to connect the CAMINO-101 serial port to the serial port on the ATC-2000WF. That's it!
We have tested this device and can confirm it works well with Rose Point Coastal Explorer on Windows-based PCs, and iNavX, SEAiq and Nobeltec Timezero on iOS devices (iPhone and iPad). If you need to multiplex two marine devices (such as a chartplotter and an AIS system) into a single wireless data stream, consider the Comar NMEA-2-WIFI Convertor.

The installation went very well, I had a question on the baud rate of radio to adapter, it was answered promptly. The AIS targets appear on an overlay of the charts in iNavX, as described. As of now, we have not left the dock in Port Aransas, Texas, but we plan to in June for an extended cruise. It is refreshing to find a product that works as advertised. Thank You.

Installation was a piece of cake. installed in conjunction with the Standard Horizon Matrix AIS/GPS (GX2200) to show AIS targets on my Samsung Galaxy 10 tablet running Open CPN, works great!
