This ActisenseŽ Quick Network Block
(QNB-1) allows backbone networking connections to be made easy and
fault-free on National Marine Electronics Association (NMEA) buses and
networks.
The QNB-1 is two products in one, being compatible with both NMEA 0183 buses
and NMEA 2000 networks:
- When used on an NMEA 0183 bus, the QNB-1 provides an
easy junction box to connect multiple NMEA 0183 devices together. An NMEA
talker device is connected to one of the network connection points, while
each NMEA listener device is connected to the remaining connection points.
No amplification or isolation buffering is included in the QNB-1
- if this is important, the
NMEA Buffer (NBF-2) should be used instead.
- When used on an NMEA 2000 network, the QNB-1 is a
multi-drop network backbone connection block, adhering to the barrier
strip connection type detailed in the NMEA 2000 specification. This allows
for 2 backbone connections (in & out), up to 6 drop connections and a
power entry point.
The power entry connection is protected by two 4 Amp fuses, providing
current protection to each half of the network backbone.
Useful LED indicators show power status, detect a power reversal, indicate
whether the fuses are still intact, and detect the presense of data on the
connected bus or network.
