NMEA 2000 Ethernet Gateway - YDEN-02

YDEN-02 Ethernet Gateway

The Gateway connects navigation PCs and laptops to NMEA 2000 over Ethernet, Garmin Marine Network, Raymarine SeaTalk HS and RayNet, Furuno NavNet, or NMEA OneNet, and allows bridging of NMEA 2000 networks.

The Gateway is equipped with a standard Ethernet RJ45 connector, and you may need a proprietary adapter to connect it with your vessel's network; direct connection to PC with standard computer cable is also supported.

The Device provides NMEA 0183 and NMEA 2000 data streams using TCP and/or UDP protocols, and has a bi-directional converter between NMEA 0183 and NMEA 2000. This allows viewing of navigational data including AIS as well as managing NMEA equipment including autopilot from virtually all marine software, e.g. OpenCPN (NMEA 0183 only) and Expedition 10 (both NMEA 0183 and NMEA 2000 protocols are supported). The Gateway has three data servers (TCP/UDP), which allows tailored settings for different applications.

The Web Gauges page of the built-in web site allows managing of a digital switching equipment and real time viewing of vessel data using a web browser on PC, laptop, tablet or smartphone; no internet connection or app installation is required. If you have access to your boat Ethernet network over the internet, Web Gauges are a ready solution to monitor and manage your vessel.

The built-in web site also allows configuration of the Gateway and updating of the firmware, it also allows viewing NMEA 0183 and NMEA 2000 data streams right from a web browser for diagnostics. The Gateway automatically records your track with weather, depth and other data (the same as Wi-Fi Router) to the internal memory (up to 12000 points). These data can be saved from the internal web site to GPX (for Garmin MapSource, Google Earth or other cartographic applications) or CSV (spreadsheet) files.

Moreover, you do not need to install applications to view realtime vessel data. We added colorful, web-based gauges to built-in administrative web site, and now you can view wind, engines and fuel rate, pressure of oil, coolant and fuel, tanks and batteries (or using circular gauges), course, speed, depth and other data right from a browser. You can customize any page's layout and its sets of data bars. You can even watch NMEA logs! Save on apps, save on additional instrument displays and monitor your boat from your sofa with a smartphone! No internet connection is required and it is free. See this guide to learn more about the built-in web gauges.

If the Gateway has an internet connection, it can automatically upload recorded data to Cloud Services. Cloud Services allows easy access to your tracks from home and lets you share your position with family and friends. To learn more about Cloud Services, visit: https://cloud.yachtd.com/

Features of the Gateway:

  • can be configured for static IP address, or to obtain an IP automatically, or work as a DHCP server;
  • is compatible with 10 Mb/s, 100 Mb/s and 1000 Mb/s Ethernet networks;
  • provides high-voltage galvanic isolation between NMEA 2000 and Ethernet interfaces;
  • support mDNS and Bonjour protocols for easy discovery in the network;
  • powered from NMEA 2000, low power consumption (less than 50 mA);
  • pair of Gateways can bridge two NMEA 2000 segments over Ethernet.

The Ethernet Gateway is supplied with a connector compatible with Raymarine SeaTalk NG or NMEA 2000 Micro Male connector (see the picture below). For other networks, an adaptor cable may be required. The device model is shown on the case.

 Note that Ethernet cable is not supplied with the Gateway, for direct connection with a PC or Garmin Marine Network, a regular RJ45 Male-Male Cat 5e/6 cable is required (can be purchased in any computer store). For Raymarine RayNet, use cables with Raymarine part numbers A62360, A80151, A80159; for Raymarine SeaTalk HS use cables with part numbers E55049, E55050, E55051.
