Expand the connection options of an NMEA 0183 device, or create a flexible NMEA 2000 network with multiple drops and power distribution ...
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:
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.
