The application of this module is to interconnect serial sources, which are sending 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 RS 422 output. The NMEA inputs are among themselves, to the Ethernet output as well as to the RS 422 output galvanic isolated. The system status will signalize as common alarm by a relay contact, by an Error LED and by a serial telegram.
