NMEA 2000 Gateway

The newer NMEA 2000 transmits data through a single backbone. It simplifies the connection and shares information among different devices by using a single bus.

Most new marine instruments are now equipped with NMEA 2000 standards as the preferred method of connecting various devices on a boat. While NMEA 2000 is currently the main standard for inter-connecting new marine electronic equipment on vessels, the old NMEA 0183 standard has been around for a long time and will continue to be used for a the foreseeable future.

The NMEA 2000 gateway allows boat users to connect NMEA 0183 equipment to an NMEA 2000 network and vice versa. Quark-elec NMEA 2000 gateways have a bi-directional converter with wide support of message types including AIS, DSC and autopilot.

NMEA 2000/0183 bi-directional gateway + USB + WiFi

QK-A032-AIS – NMEA 2000/0183 Bi-directional Gateway + USB + WiFi

‘Converts 0183 to 2000 and vice versa, and through WiFi’


The QK-A032-AIS NMEA 2000 bi-directional gateway provides straight forward connection of NMEA 0183 equipment to NMEA 2000 networks and vice versa.

This bi-directional gateway will enable you to:

  • Connect NMEA 0183 equipment to your NMEA 2000 bus
  • Convert NMEA protocols in both directions, 0183 to 2000 and 2000 to 0183
  • View the combined data through a chart plotter or USB and WiFi

QK-A034-B Bi-directional WiFi to NMEA 2000 Gateway Multiplexer with NMEA 0183 and SeaTalk input

‘Effortlessly connects the NMEA 0183 sensors to my NMEA 2000 chart plotter and smart phone’


The QK-A034-B is a sophisticated NMEA 2000 to WiFi and USB multiplexer, with added flexibility for your growing system.

Enjoy a direct WiFi link to your NMEA network data, for convenient and flexible access to your marine data. As 2-way communication is allowed through WiFi, you can also send data, including waypoints to your chart plotter and autopilot.

In addition to bi-directional NMEA 2000 to WiFi and USB, the A034-B provides a seamless connection between NMEA 0183 and Raymarine SeaTalk1 input devices.

NMEA 0183 protocol bridge

QK-AS03 NMEA Protocol Bridge

‘Converts NMEA 0183 RS422 communication to RS232 and vice versa’


Early versions of the NMEA 0183 standard specified that listeners and talkers need to be isolated and single-ended. Later versions of the standard retained the opto-isolated listener recommendation, but revised the talker requirement to be differential-ended, as RS422 compliant. As a result, there are some NMEA 0183 instruments with single-ended and others with RS422 interfaces.

The AS03 resolves the issue of converting the balanced signal output by NMEA 0183 RS422 products to the unbalanced signal required by older NMEA 0183 RS232 instruments and chart plotters and vice versa.
