The NMEA 2000 Range

Actisense QNB-1 Quick Network Block

Fault-free, NMEA 2000® backbone connections.

The QNB-1 is available in two versions:

The QNB-1 version is fitted 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.

The LEDs provide information for the installer during set up and to indicate the presence of data, power status, power reversal and to show whether the fuses are intact.

The QNB-1-PMW version is fitted with six standard NMEA 2000 M12 (Micro-fit) 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.


  • High quality NMEA 2000 barrier strip connections
  • Diagnostic LEDs
  • Uses standard ATO fuses


  • One unit provides six NMEA 2000 drops
  • Power feed is split to enable longer networks
  • Separate fusing for split power feed provides an easy way to isolate network segments
  • Simple installation on Mini and Micro networks using bulk cable
  • Easy to mix & match NMEA 2000 with Raymarine STNG on opposite sides
