NBF-3 NMEA 0183 Buffer
Safely drive up to six NMEA Listeners, with power distribution for the connected Talker.
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.
Please note: This product has now been retired. Please see PRO-NBF-1 as a great alternative.
Isolation on the input and outputs ensures the protection of the source Talker device and Listening devices.
ISO-Drive™ technology on the outputs and OPTOisolation on the input enables you to connect the NBF-3 with complete peace of mind.
The NBF has the addition of power distribution for the NMEA Talker. By having power and data from the same source, cabling requirements are reduced, and installation is made simpler.
