NMEA multiplexer YDNM-02

for yachts

Smart multiplexer with five NMEA 0183 ports and one SeaTalk port, auto detection of port speed and easy configuration with a click of a button! And, of course, it has flexible filters, routing rules, and supports firmware updates. The underlying idea was to create simplest multiplexer in the world. In our lab, the project was called "Simple Multiplexer", but later we added a lot of features and removed the word "Simple". Nonetheless, we are sure that it is still the easiest to install. Instead of a laptop and software, you'll only need a paperclip. The Multiplexer has six configuration presets with different port speeds and routing schemes. Presets can be selected by pressing a hidden button. Ports can be configured to auto-detect the speed of connected equipment. In Preset #1 (see Picture 1), 3 of the 5 ports are configured for "AUTO" speed. This means that you need not worry about the speed of the NMEA 0183 equipment that you connect. Port #4 in the Preset #1 is configured for 4800 bps, but you need not worry that it will be flooded by AIS messages from Port #5, because according the routing scheme, it receives data from ports #3, #4 and SeaTalk. Ports can be routed to themselves, which allows multiplexing of data from SeaTalk and 5 different NMEA 0183 talkers (see Preset #6 on Picture 6) and sending them to 3 or more different listeners (multiple listeners can be connected to a talker, but a listener can receives data from only one talker). If you find no suitable preset, you can change any setting of any preset: speed, routing, data filters or tunnel mode. This can be done with a command sent to any port of the Multiplexer.
