The NSR NND-200 is a marine NMEA distributor and buffer designed to receive navigation data from multiple sources and distribute it to several onboard navigation and communication equipment systems.
It provides 4 NMEA inputs and 8 NMEA outputs. Its built-in optical-coupled isolation protects connected equipment against electrical interference and voltage surges.
The unit contains two independent NMEA buffers, each providing 2 inputs and 4 outputs. It can be used for distributing GNSS, GPS, gyrocompass and other NMEA navigation data to radar, ECDIS, AIS and other compatible marine equipment.
4 input channels and 8 output channels.
Two independent 2-input / 4-output buffers.
Built-in optical isolation.
Supports baud rates up to 38,400 bps.
GNSS input redundancy selection.
LED indication for input and output status.
Designed for marine navigation systems.
