QNB-1 Quick Network Block
An Ideal NMEA 2000 networking solution for areas of high instrument density.
The Actisense QNB-1 provides instrument drops for up to six NMEA 2000 devices offering a flexible 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 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.

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.

Both versions are fitted with LEDs that provide information during set up and use to indicate the presence of data, power status, polarity and to show whether the fuses are intact.
