This Actisense™ 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.
