Before getting started
The wire colours used in this quick start guide are in accordance with
the NMEA 0183 specication (v.4.10, June 2014) and are for illustration
purposes only. Please ensure you check the wiring colours in the installation
instructions for the device you wish to interface to the NBF-3.
Introduction & Features
Ground breaking and innovative ‘ISO-Drive™’ technology from Actisense
protects up to six NMEA 0183 Listeners from damage that can be caused by
hazardous ground loops. Electrical isolation on the NBF-3 input also provides
protection to the connected Talker.
Data is distributed identically from each of the six outputs and at least the
original signal voltage levels. This means that information sent by the connected
Talker is reliably delivered to its intended destination, even over long cable runs.
The addition of power distribution for the NMEA Talker allows a single cable to
connect power and data to the Talker.
