For exchanging navigation data according to IEC 61162
The VEINLAND product range includes a variety of different NMEA expanders and multiplexers to ensure the exchange of navigation data between navigation devices and they fulfill the IEC 61162 regulations. All modules are galvanic isolated and partly secured by a redundant voltage supply. A differential serial data transmission is available as RS 422 as stated under NMEA 0183.
NMEA expanders distribute signals received (e.g. from echo sounder or GPS) to a maximum of 12 receivers. Individual modules can automatically switch to the redundant secondary input if the primary input fails.
NMEA multiplexers collect various data from a maximum of 8 transmitters, combine and send them to different receivers, e.g. Radar or ECDIS. In addition to the standards above, our multiplexers can filter, modify and recalculate the signals as well. Headers and checksums can be changed via the configuration software directly on-site when installation takes place. Special solutions such as the calculation of the true wind or invert wind directions by 180 ° are possible.
One of our most popular developments includes a fully configurable high-performance 8-channel NMEA matrix with a network interface according to the IEC61162-450 standard.
A large selection of our NMEA products are certified according to the IEC 60945 standard. Special solutions can be further developed on request.
