Veinland 1NMEAto4 Expander 4 Channel

The VEINLAND product range includes a variety of different NMEA expanders and multiplexers to ensure the exchange of navigation data between navigation devices according to IEC 61162. All modules are galvanic isolated and partly secured by a redundant voltage supply. According to NMEA 0183, a differential serial data transmission is available as RS 422.

NMEA expanders distribute received signals e.g. from echo sounder or GPS to up to 12 different receiver. Individual modules can automatically switch to the redundant secondary input if the primary input fails.

NMEA multiplexers collect various data from up to 8 transmitters, bundle and send them to different receivers, e.g. Radar or ECDIS. In addition to the standards, our multiplexers can filter, modify and recalculate the signals as well. Headers and checksums can be changed via the configuration software directly on site during the installation. Special solutions like the calculation of the true wind or invert wind directions by 180 ° are possible.

Our new development includes a fully configurable high-performance 8-channel NMEA matrix with a network interface according to the IEC61162-450 standard.

A big selection of our NMEA products are certified according to the IEC 60945 standard. Special solutions can be developed on request.
 

Overview

The 1NMEAto4 is used for the distribution of data from one serial source (NMEA or RS232) to max. 4 receivers (RS422 or NMEA). By using NMEA as a serial source, the RS232 interface can be used for the monitoring  of the data streams. The four outputs of the module are individually selectable by switches to RS422 or NMEA. The NMEA input is galvanically isolated from the RS232 interface, the 4 outputs, and the power supply.
