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 0183 to NMEA 2000 mini gateway

QK-AS01 NMEA 0183 to NMEA 2000 mini gateway

The QK-AS01 provides an easy solution to linking older NMEA 0183 devices to the newer NMEA 2000 network by converting NMEA 0183 output sentences to NMEA 2000 PGNs. The QK-AS01 is compatible with most NMEA 0183 devices and supports the majority of NMEA 0183 sentences.

  • Designed to easily fit onto most surfaces
  • Small enough to fit behind instrument panels
  • Compatible with most NMEA 0183 devices
  • Supports the conversion of the majority of NMEA 0183 sentences

NMEA 0183 to 2000 converter with AIS/GPS receiver and ethernet output

QK-A027-plus NMEA 2000 AIS Receiver with NMEA Multiplexer + N2K Converter + Ethernet+WiFi + GPS

‘Quark-elec’s first AIS receiver supporting Ethernet output.’

The A027+ is a commercial level AIS/GPS receiver with multiple routing functions. Data generated from the built-in AIS and GPS receivers, the NMEA 0183, and Seatalk1 inputs is combined by the multiplexer and can be forwarded to WiFi, Ethernet (RJ45 port), USB, NMEA0183 and N2K outputs.

Whether you are using a tablet, a mobile phone or an onboard computer, you can easily connect the device to your on-board navigation system. The A027+ can also be used as an AIS shore station which can receive and transfer AIS data to a remote server via the internet by government bodies.

It has a greater AIS range of 45nm, similar to the commercial grade A026+, however, as it is a one-way interface, the A027+ is perfect for those wanting the extra AIS range, but do not need the additional features that the A026+ provides. This keeps the A027+ pocket-friendly, while still offering more advanced functions than the entry-level 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.
