The Router has all the features of the Gateway YDWN-02 (on the left), but has four physical NMEA 0183 ports and a SeaTalk port (multiple SeaTalk devices can be connected). An internal bi-directional converter between SeaTalk and NMEA 0183 allows use of SeaTalk data in NMEA 0183 and vice versa, including SeaTalk autopilot control from NMEA 0183.

For a price of a usual NMEA multiplexer, you are getting a device with very flexible settings which can be easily configured using a web browser on a smartphone or PC. You can change the port speed or stop forwarding data from one port to another with a click. The Router can also multiplex Navtex data streams and NMEA 0183 sentences without a checksum. This is called “tunnel mode” and can be turned on for any physical port or data server. This product is an ideal solution if your new chart plotter has only one NMEA 0183 port and you need to connect it with all your other older equipment.

Features (in addition to YDWN-02):

four NMEA 0183 ports, one is galvanically isolated (2500 VRMS);

one SeaTalk port, can pair SeaTalk equipment with NMEA 0183 hardware or software;

allows control of SeaTalk autopilots from NMEA 0183 hardware or software;

a pair of routers can act as a SeaTalk or NMEA wireless extender and allows joining of two or more physical devices;

supports $STALK sentence of NMEA 0183 for raw SeaTalk datagrams.
