The N2K0183 multiplexer is a bridge between Nmea0183 and N2K devices. The unit contains a bidirectional N2K bus interface, with N2K to Nmea0183 and Nmea0183 to N2K converters. The unit can convert data from N2K sensors so that their data can be transferred, as Nmea0183 messages, by WiFi or wired connections to your smartphone or laptop computer, turning it into a powerful chart plotter. The multiplexer component of the unit operates using Nmea0183 data, and filters and directs messages to multiple output streams. In addition to the main bidirectional N2K input, the device includes two further opto-isolated Nmea 0183 input ports, allowing easy connection to Nmea0183 only devices such as some AIS receivers. Data in Nmea0183 format can also be accepted wirelessly into the multiplexer from UDP TCP and an 'EXT' paired multiplexer. Filtering is possible on the Nmea0183 sentences and on the N2K bus messages. Once filtered, the input streams are combined and routed by the multiplexer, which can direct messages in Nmea0183 format wirelessly to UDP, TCP, and 'EXT' outputs as well as to the wired Nmea 0183 output port. This wired serial output data is also available at the micro USB port on the device. The multiplexer can also be used as a debugger or analyser of the data that travels on the N2K bus, and can recognise and identify most common N2K messages.
This multiplexer is the result of the collaborative work between me and Richard Clutterbuck (dagnall) to whom I am very grateful.
