  • Page 4: Introduction

    Introduction The NMEA 2000 Wi-Fi Gateway (hereinafter Gateway or Device) allows you to see data from an NMEA 2000 marine digital network on a PC or smartphone. With it, you get marine network data including vessel course, speed, position, wind speed and direction, water depth, AIS messages from vessels and aircrafts and other navigation data in popular software applications.
  • Page 5 The Gateway supports TCP and UDP network protocols (both can be enabled at the same time). For UDP protocol, the number of clients (physical devices or software applications) is unlimited. A pair of Wi-Fi Gateways can act as an NMEA 2000 wireless extender and allows joining of two or more physical networks.

  • Page 6: Warranty And Technical Support

    Warranty and Technical Support The Device warranty is valid for two years from the purchase date. If a Device was purchased in a retail store, the sales receipt may be requested when applying for a warranty claim. The Device warranty is terminated in case of this Manual instructions violation , case integrity breach, or repair or modification of the Device without the manufacturer’s written permission.

Yacht Devices Ltd declares that this product is compliant with the essential requirements of EMC directive 2014/30/EU and radio and TTE directive 1999/5/EC. Dispose of this product in accordance with the WEEE Directive. Do not mix electronic disposal with domestic or industrial refuse.

  • Page 9: Device Installation And Connection To Nmea 2000 Network

    II. Device Installation and Connection to NMEA 2000 Network The Device requires no maintenance. When deciding where to install the Device, choose a dry mounting location. Avoid places where the Device could be flooded with water, as this can damage it. Note that conductive materials (metals) weaken the Wi-Fi signal or may even completely block it.
  • Page 10 After connecting the Device, close the lock on the connection to ensure it is water resistant and firmly secured. When powered on, the Device produces a single green flash to indicate that power is supplied. After that, the Gateway will produce a series of four flashes every five seconds (see details in Section VI).

  • Page 11: Wi-Fi Settings

    III. Wi-Fi Settings The Device can operate in either Access Point mode (which is the factory default) or in Client mode — when connected to an existing Wi-Fi network. To configure the Gateway, you need any Wi-Fi enabled device (laptop or smartphone) with a web browser.
  • Page 12 Wi-Fi channel. This issue may be caused by congestion or signal interference on the channel. To resolve this, assess nearby Wi-Fi network channels using a Wi-Fi scanner mobile app that shows nearby Wi-Fi channel usage and signal strength and select the most free channel.
  • Page 13 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 password.
  • Page 14 conflicts, it is recommended to assign the Device IP address from the same subnet but with a different address, such as 192.168.4.100. Contact your router administrator or refer to your router documentation if you have problems with the Wi-Fi setup. The «Save»...

Alternatively, you may need to use a different port, say, if you use port forwarding on the router. You can change the Device web-interface HTTP port on the Device’s «Home»...

  • Page 17: Configuration Of Application Protocols

    IV. Configuration of Application Protocols Figure 3. Settings of OpenCPN application Most marine applications support both TCP and UDP network protocols. TCP is a connection-oriented protocol. This means that the receiver must confirm reception of data before it gets the next packet of data, otherwise the sender repeats the transmission after a timeout.
  • Page 18 UDP is a connectionless protocol; any number of clients can listen to data broadcasted from a specified port without any additional load on the server and without increasing the actual network traffic. We recommend using UDP protocol where possible, because the resources of the Device’s CPU are limited.

  • Page 20 With the factory settings, Gateway has the Server #1 enabled and pre-configured to use TCP port 1456 and the NMEA 0183 data protocol. To connect your application to the Gateway with factory settings: • connect your laptop or mobile device to YDWG network; •...

  • Page 21: Nmea 0183 And Nmea 2000 Message Filters

    V. NMEA 0183 and NMEA 2000 Message Filters The Device has 14 filter lists which allow limiting the set of messages passed from the NMEA 2000 network to a PC or mobile application (transmit filters) and messages passed from the application to the NMEA 2000 network (receive filters). Each NMEA server has four filter lists: two for incoming and outgoing NMEA 0183 messages, two for incoming and outgoing NMEA 2000 messages (used for RAW protocol).
  • Page 22 The sentence ends by a checksum after the * (asterisk) symbol. Gateway with factory settings using «YD» talker ID, it can be changed on the «NMEA Settings» page (see X.2). The Device uses 3-char sentence formatters only for filtering. The following sentences matches to GLL and VDM records (sentence formatters): $GPGLL,4146.5894,N,07029.6952,W,173412.02,A*15 !AIVDM,1,1,,B,13A0B20vim1560hOldUqEWQnH<2K,0*4D...

  • Page 26 During normal operation, the Gateway produces a series of four flashes every 5 seconds. With the factory settings, the Gateway should flash GREEN-GREEN-RED-GREEN, and when you open the web interface in the web browser (http://192.168.4.1), the Device will blink all green while pages are loading. LED signals during device reset using the hidden reset button are described in Section VII.

  • Page 27: Settings Reset And Hardware Reset

    VII. Settings Reset and Hardware Reset Insert the paper clip (at a right angle to the device face) in the small hole at the end plate of the Gateway. The Gateway LED will constantly shine red when the hidden button under the hole is pressed. Wait 2-3 seconds and the LED will change from red to green.

    VIII. Diagnostics Data Recording Diagnostics is designed to troubleshoot issues with software applications. A log contains all sent and received NMEA 2000 messages and all data sent and received from and to the NMEA server #1 port (see Section IV). The NMEA server #3 can be configured to send log data in a real time to a web browser or terminal application.
