ZNR-208
ZNR-208 8ch NMEA Buffer with auto switch
Introduction
ZNR-208 8ch NMEA Buffer is a high reliable serial data distributor for relaying NMEA 0183 data to 8 listeners. It receives 2 NMEA signals and splits one of them into 8 NMEA output ports.
It is very useful for safety navigation with protecting system faults. If one GPS input signal is lost then ZNR-208 selects another GPS input signal automatically (or manually), and it maintains to output without any system errors.
ZNR-208 is able to receives any type of serial data such RS422, RS232, 5V TTL signal. Also, it has both high voltage protection and reverse input protection too. 2 output ports of 8 outputs are able to be selected RS422 or RS232 type. This NMEA Buffer provides full DC isolation between input signal, output signal and input power each other.
NMEA Buffer is also called as a splitter, a distributor, an expander and an amplifier.
