product's model: NM-431MP NMEA Ethernet Gateway
 Our Price: 240.00€


The NM-431MP is a multiport IO interface featuring four optically isolated input ports, three RS-422 signal level output ports, one RS-232 signal level IO port (shared with input 1) and a Serial over Ethernet IO Interface. The NM-431MP interface is intended for use with computer based marine systems such as ECDIS, SVDR/VDR and Conning systems where NMEA-0183 data must be acquired from multiple sources such as GPS, Gyro, Log, AIS, Radar ARPA, Echo Sounder, Wind instrument and BNWAS. The connection to the computers is achieved via the Serial over Ethernet Interface with the use of a single CAT5 cable, either by creating four virtual serial ports or directly to four user selectable UDP sockets for application supporting this feature.



The NM-431MP can acquire serial signals provided that these follow the 4.800-38.400/8/N/1 standard. These four input signals can then be inputted from the target computer application via the Serial over Ethernet interface, either by creating four virtual serial ports (VSP), or directly from the assigned UDP sockets. Outputs from the computer software (e.g. signals to the autopilot from the ECDIS) can be delivered via the same Serial over Ethernet Interface to each of the three NM-431MP output ports carried in RS-422 signal level format.
