KM-Multi 12X

Latest top of the range 12 inch model from Onwa Marine. What a move forward this new model is – with a fantastic new 1024 x 768 resolution screen and NMEA2000 data. The KM-12X and its 8 inch sibling, KM-8X, are Onwa’s flagship chart plotter products. These high end plotters come with a built in Class B+ AIS transceiver and a 600/1000 Watt sounder/fish-finder. The AIS unit installed is the new more powerful Class B+ version that transmits at 5 Watts – over twice that of the old Class B version and uses SOTDMA technology, the same as Class A systems. With so much in one package, is is possible there could be even more? Well yes there is, as an Onwa Radar can be added at any time. It’s plug and play to do – just install the radar transmitter hardware and plug a network cable from the radar antenna into the plotter and -job done! All the controls for the radar antenna and the dedicated radar screens are already built into the KM-plotter. Once the radar signal is present, the KM-plotter becomes a fully fledged radar set with the choice of a conventional radar screen or have the radar trace overlaid onto the chart. Overlaid makes sense of all those mysterious wisps of radar trace when they are overlaid onto the chart itself.

A new feature to Onwa plotters is the move to NMEA2000 as a data transfer method whilst still  retaining NMEA0183 functionality so as to be compatible with other 0183 equipment. Not content to move just from NMEA0183 to embrace NMEA2000 , the Onwa design team have gone another step forward and introduced the latest NMEA networking protocol, NMEA OneNet as well.
