The Actisense NBF-2 galvanically opto-isolates and buffers NMEA 0183 data to drive multiple NMEA devices, such as chart plotters and radars. It is ideal for safely interfacing an on-board PC to NMEA 0183 equipment on a vessel.
Designed for use with all NMEA 0183 input and output types (RS422, RS485 and RS232), the NBF-2 produces an amplified copy on each of its isolated outputs.
Galvanic isolation on the OPTO input and the ISO-Drive outputs ensures protection for both the source talker device and all listening devices, exceeding the NMEA 0183 specifications.
The NBF-2-GX version has seven glands which offer's the option to easily seal more connections.
The NBF-2 and NBF-2-GX are invaluable in creating a safe and flexible NMEA data network.
Benefits of the NBF-2:
Protects connected devices
Seal more connections with the NBF-2-GX
Can be used to isolated between two systems
Note: The NBF-2 and NBF-2-GX are being phased out of production and are likely to be unavailable from mid-2014.
The NBF-3 is the latest and enhanced version of the Actisense NMEA Buffer.
