Before getting started
The wire colours used in this quick start guide are in accordance with
the NMEA 0183 specication (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.

Powering the NBF-3
The NBF-3 is compatible with 12V and 24V power supplies and should be
connected to the battery in accordance with the diagram below:
Connecting to Devices
Strands of wire must not be twisted before inserting in to the connector, this
will ensure a much more secure termination than if the wires are twisted.
A small at headed screwdriver (2-3mm) is needed to loosen the screws on the
pluggable connectors for the wires to be inserted or removed.
NMEA 0183 and RS232 (serial PC) connections
Colour Blue Green
Name Power indicator Listener Port Data
The NBF-3 power connection is routed to the Listener port PWR OUT connection
via a self-resettable fuse. This provides the option to power the NMEA 0183
Talker from the NBF-3.

Mounting the NBF-3
The NBF-3 can be mounted on a DIN rail or directly to a bulkhead via the
screw holes in each corner. We recommend the DIN rail mount option for the
convenience of removing and re-installing the NBF-3 at a later date if needed.
