Safely drive up to six NMEA Listeners, with power distribution
for the connected Talker.

The Actisense NBF-3 NMEA Buffer isolates and
buffers NMEA 0183 data, with the power to drive multiple devices.
The NBF-3 can 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.

The isolation on the input and each of the outputs ensures the
protection of the source Talker device and all the Listening
devices. The safe connections mean that a non-isolated device could
be connected and the NBF-3 would prevent it from causing any damage
to the other equipment in the system. Ground loops often occur when
devices are not isolated and can cause irreparable damage.
Actisense ISO-Drive technology on the outputs along with the
galvanic opto-isolation on the input means you can connect the
NBF-3 with complete peace of mind.

The NBF-3 NMEA Buffer 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 simple.
