The NND-200 NMEA Distributor contains two NMEA buffers:

Buffer 1: 2 inputs/4 outputs. When used for GNSS buffer, all 4 NMEA outputs will keep on unless both GNSS inputs fail simultaneously. When both Input 1 and Input 2 are valid, only Input 1 will be selected as default.

Buffer 2: 2 inputs/4 outputs. Same as Buffer 1.

So, Buffer 1 and Buffer 2 combined, provide 8 NMEA outputs from 4 inputs.

With a built-in optical-coupled isolator, the distributor is a reliable and professional device, which can be used on board. The external equipment connected to the distributor can be safely protected from lightning surges on line.
