NMEA Buffer / Splitter

NMEA Buffer, sometimes called Splitter or Expander or Amplifier, collects NMEA 0183 data from single (or dual) talker, and then send the data to multiple NMEA 0183 Listener.

This NMEA Buffer can receive all of RS-232, RS-422 and TTL signals, and is galvanic isolated. The output of NMEA 0183 conform to RS-422 specifications. Therefore, this can be used for RS-422 Splitter as well as NMEA Splitter.

Most NMEA Buffer/Splitter/Expander has two inputs. So, in case of data stop at one input, and then it switch another input data automatically or manually.

NMEA Buffer / Splitter – ZNR-416 (4-16ch)

NMEA Buffer, ZNR-416 is a smart and big NMEA buffer. And it is world’s first product which has 4 inputs and 16 outputs what can be used as 1 or 2 or 4 separate logical units. Therefore this buffer is very suitable for where one big buffer which has many output ports required, or more than two buffers are required at same time.

ZNR-416 NMEA Buffer is operated as following 3 modes.
– 1 Unit x 16 Outputs NMEA Buffer (2 Inputs)
– 2 Units x 8 Outputs NMEA Buffer (each 2 Inputs)
– 4 Units x 4 Outputs NMEA Buffer (each 1 Input)

If one input signal is missed, then ZNR-416 automatically(or manually) selects another input signal and it maintains to output without system error. It was designed for considering high reliability and in accordance with IEC61162-1/2, IEC60945 standard.

NMEA Buffer / Splitter – ZNR-214 (2-14ch)

NMEA Buffer, ZNR-214 has 2 NMEA inputs and 14 NMEA outputs. And ZNR-214 is very useful for safety navigation with protecting system faults. If one GPS signal is lost when use 2 GPS receivers, ZNR-214 automatically(or manually) selects another GPS signal, and maintains to output signal without any system faults.

This NMEA Buffer receives almost type of serial data such as RS422(NMEA), RS232, 5V TTL signal. Also ZNR-214 has both high voltage protection and reverse input protection.

And two NMEA-0183 output ports are for RS232 type signals.
