Details

The NBF-3 NMEA Buffer isolates and buffers NMEA 0183 data, with the power to drive multiple devices. Able to distribute up to six identical, amplified streams of data from one source. The NMEA signals are buffered to ensure that each Listener receives the data at the required voltage levels, providing consistent data quality.

Features:
  • One OPTO-isolated input Six ISO-DriveTM outputs
  • Compatible with RS422, RS232 and RS485 connections
  • Pluggable screw terminals
  • Power and input indicator LEDs
  • Power feed (500 mA) for single cable installations to the NMEA Talker
  • Optional DIN rail mount Up to 115200 baud
  • Outputs automatically track the input baud rate
  • Protocol independent
Benefits
  • AIS compatible
  • Protects connected devices
  • Simple installation
