  • Page 9: Nmea 0183 Basics

    II. NMEA 0183 Basics The default baud rate of a NMEA 0183 interface is 4800 baud. High-speed interfaces are 38400 baud and were designed especially for AIS, but usually chart plotters and instrument displays allow any data (not only AIS) on a high-speed port. On a chart plotter, port baud rate a.k.a. speed can be configured in the NMEA 0183 interface settings.
  • Page 10 Voltage on the TX− line (dotted on Figure 2.b) changes from 0 to 5V, and connecting this line to ground line can cause a short circuit. The correct connection schemes are shown in Figure 3. Figure 3. Connection of NMEA 0183 devices — 10 —...

  • Page 11: Device Installation And Connection

    III. Device Installation and Connection The Device requires no maintenance. When deciding where to install the Device, choose a dry mounting location. Despite the fact that the Gateway case is waterproof, the terminals are open and fluids can enter the Device and/or cause a short circuit. Do not place the Device where it can be flooded by water, get wet in the rain or be sprayed with any other fluids.
  • Page 12 Warning! Incorrect wiring may damage the Device and/or connected equipment ports! The Gateway is supplied with NMEA 0183 Ports configured for 4800 baud. If your NMEA 0183 equipment has a different baud rate, configure the corresponding Gateway Port baud rate before connecting to NMEA 0183 equipment (see Section IX.1).

    • Port LED, flash #2: RX errors. Green, if any data was received and all data was received without errors. NMEA 0183 sentences contain a checksum, so any transmission error will be detected. • Port LED, flash #3: data sent. Green, if data was sent to this Port. As RS-422 does not support confirmation of reception, this signal does not mean that data was received by any Listener.
  • Page 14 • Port LED, flash #4: TX overflow. Green, if data was sent without overflow. In case of a red signal, you should increase the Port baud rate (if possible) or filter our unnecessary data, because the selected baud rate is not enough to send all the data. This signal will also be red if flash #3 is red. With the factory settings, the Status LED should flash GREEN-GREEN-RED-RED after the power on;...

  • Page 15: Wi-Fi Settings

    V. Wi-Fi Settings The Device Wi-Fi module can operate in either Access Point mode — creates its own Wi-Fi network (factory default) or in Client mode — connected to an existing Wi-Fi network. To configure the Gateway, you will need a Wi-Fi-capable device such as a laptop or smartphone with a web browser. The Gateway's internal web server has limited capabilities, and it is not advisable to have multiple devices accessing it simultaneously.
  • Page 16 Note that the Device allows you to select from all available 2.4 GHz channels, from 1 to 13. As of 2024 in North America you are allowed to use only channels 1–11. EU, Australia and Japan has no such limitation. Check local laws and regulations with regard to restrictions on the use of Wi-Fi channels.
  • Page 17 In Wi-Fi Client mode, the Device connects to an existing Wi-Fi network. To switch the Device to this mode from the default Access Point mode, use the «Wi-Fi Client» page in the Device's web interface. To connect to your Wi-Fi network, you can either scan for available networks or manually enter your network name (SSID) and passphrase.
  • Page 18 Contact your router administrator or refer to your router documentation to get more specific instructions on the Wi-Fi setup. The «Save» button will save the settings in the EEPROM and the settings will be applied the next time you connect to the Wi-Fi network. The «Save & Apply» button saves settings and immediately attempts to apply them if the Gateway is already in Client mode.
  • Page 19 If you cannot diagnose what is wrong, you can reset the Device’s settings (see Section VII) and the Device will be returned to Access Point mode. You can connect to the «YDWN» network again and try to change the settings one more time. 4.

  • Page 20: Configuration Of Application Protocols

    VI. Configuration of Application Protocols Figure 6. Device Data Server page with example settings The Device has three Data Servers, each of which can be individually configured. You can enable or disable Servers, select the Network Protocol and Port, and choose the Data Direction for each Server. Note that Server #1 is used by Web Gauges, so if you plan to use Web Gauges, keep Server #1 enabled.
  • Page 21 It is recommended to use the UDP protocol whenever possible. As Device has only NMEA 0183 Ports, the only available Data Protocol you can set on Servers is NMEA 0183 (except special protocols on Server #3). NMEA 0183 Data Protocol is supported by almost all marine applications.

  • Page 25: Settings Reset And Hardware Reset

    VII. Settings Reset and Hardware Reset Settings reset can be used if Device is configured incorrectly (e.g. if Wi-Fi Client settings were set incorrectly and Device does not connect to router's Wi-Fi network) so you can reconfigure the Device from scratch. Hardware reset is normally not required, but it can be used for firmware rollback (e.g.

  • Page 26: Routing And Data Filters

    VIII. Routing and Data Filters Data Routing is used to organize the data flows between physical Ports and Data Servers. Factory default settings are shown on Figure 8, observe the Device is set up to send all data from physical Ports to Data Servers and vise versa.
  • Page 27 You can set complex routing rules, for example, if two different NMEA 0183 devices are connected to the same NMEA 0183 port, say port #1 (one device is Talker, another is Listener) you can enable to forward data received from Listener on port #1 to Talker on the same port #1 — enable route from port #1 «Input»...
  • Page 28 Example 1 Suppose you have AIS transceiver Talker connected to Device port #1 and NMEA 0183 autopilot Listener connected to port #2. AIS sends a lot of data and thus both AIS and port #1 baud rate is set to 38400, but Autopilot uses standard baud rate 4800.
  • Page 29 Figure 9. AIS data filter example Example 2 Suppose you have the same setup as above, with an extra NMEA 0183 data source Talker connected to Device's Listener on port #1 and Navionics application connected to Device's Server #2. Navionics (in year 2023) can only understand AIS, GPS and depth data sentences — VDM, VDO, RMC, DBT and DPT and sometimes can hang if fed with invalid NMEA 0183 sentences.
  • Page 30 Figure 10. Navionics data filter example (by «sentence formatters» list) Example 3 Suppose in addition to Example 2 we also need to block GLONASS data, we can add a second filter to Server #2 blocking all data with GN «Talker ID», shown on Figure 11: Figure 11.

  • Page 36: Recording Of Diagnostics Data

    XI. Recording of Diagnostics Data Diagnostic procedures are used for troubleshooting connected hardware and software applications. The Device can log all data sent and received by Servers and physical Ports. Configure Server #3 and set the data protocol to Debug (TCP network protocol will be used automatically) and connect a browser or terminal application to the Server #3 port.
  • Page 37 When enough data has been logged, stop logging by pressing the 'Stop' button on the browser. Some mobile browsers do not allow you to save files and we recommend that you use a laptop or PC to record diagnostic data. Some web browsers may try to reload the web page while saving, in this case, you can use the clipboard (operating system Copy All and Paste commands) and a text editor to paste and save the log data to a file.
