This ZNC-514 NMEA Combiner (NMEA Multiplexer), is a 14ch NMEA multiplexer that has 14 NMEA0183 inputs and Ethernet/RS422/RS232/NMEA2000(optional) outputs. This is very useful for interfacing most navigation/communication equipments with such ECDIS(Electronic Chart Display and Information System), VDR(Voyage Data Recorder) and RADAR, because one ZNC-514 provides all NMEA0183 data for many equipments simultaneously.

This ZNC-580 NMEA Combiner (NMEA Multiplexer) combines up to 8 NMEA-0183 input data and let out it through 2 NMEA-0183 output ports and 1 RS-232 port.  This is very useful for any equipment such ECDIS and VDR required receiving various NMEA-0183 data from many devices (multiple talkers – single or multiple listeners environment).

If the number of needed serial interfaces to control an ECDIS, a VDR or other systems on board of a vessel is not enough or the cabling between the systems contains not enough spare wires, the 4NMEA to1 module must be used. A data distribution between the connected sources is possible.

The purpose of this module is to interconnect serial sources which send serial strings according the NMEA 0183 standard. The 8NMEAto1 Ethernet module converts up to 8 NMEA sources to UDP or TCP/IP Ethernet and one RS422 output. Filtering of output strings is possible. The NMEA inputs are among themselves to the Ethernet output as well as to the RS422 output galvanic isolated. The system status will signalize as common alarm by a relay contact, by an Error LED and by a serial telegram.
