Introduction & Features
The Actisense QNB-1 provides instrument drops for up to six NMEA 2000
devices offering a exible alternative to multiple T-pieces and reducing the
cost of an NMEA 2000 installation.
The QNB-1 is available in two versions:
The QNB-1-PMW version is tted with six standard NMEA 2000 M12 (Micro-
t) female connectors which allow ‘plug and play’ connections for quick and
easy installation. A Raymarine STNG backbone can be wired to one side of
the QNB-1 to combine standard NMEA 2000 with STNG without the need for
adapter cables.
The QNB-1 version is tted with glands to allow for installation of custom
lengths of cable. This is a great option for ‘mix & matching’ standard NMEA
2000 devices with Raymarine STNG devices.
Both versions are tted with LEDs that provide information during set up
and use to indicate the presence of data, power status, polarity and to show

Powering the QNB-1
For standard operation, connect a power supply or battery with a 10 to 16 volt
output. For extended voltage range operation (16 to 35 volts), the installer
must rst check that all NMEA 2000 devices can support that higher voltage,
as the QNB-1 does not regulate the voltage supplied to it.
Connect the battery positive wire to the ‘+ BATT IN’ terminal and the battery
negative wire to the ‘- BATT IN’ terminal. Use the 4 amp fuses provided for
‘micro’ (lite) backbone cable or the 8 amp fuses for ‘mini’ (heavy) backbone
Connecting NMEA 2000 Devices to the the
QNB-1
NMEA 2000 instruments should be connected to any of the six remaining
spaces available between the power supply and the backbone terminals. See
table in ‘Connecting the backbone cable’ section for pin out. This pin out is
also the same for standard NMEA 2000 and Raymarine’s SeaTalkNG system.
Connecting NMEA 2000 Devices to the the
QNB-1-PMW
Connection of NMEA 2000 devices to the ‘PMW’ variant of the QNB-1 is quick
Mounting the QNB-1
The QNB-1 can be mounted to any at bulkhead using the screw holes located
in each of the four corners of the case. The case has been designed to be
mounted with the glands/connectors on the sides, and not the top and bottom.
Connecting the backbone cable
Using NMEA 2000 approved cabling, install the backbone cable through the
large glands to the terminals furthest from the power supply. A pin out table
is available below. This pin out is the same for standard NMEA 2000 and
LED Behaviour
‘PLRTY’ - illuminates if the BATT IN + and - are the wrong way around
‘PWR’ - indicates presence of power on BATT IN
‘FUSE1’ & ‘FUSE2’ – illuminates when corresponding fuse is good and intact
