Description
QK-A034B 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. And as the WiFi connection is 2-way, you can also send data, including Waypoints to your chartplotter and autopilot.
In addition to bi-directional NMEA 2000 to WiFi and USB, the A034B provides a seamless connection of NMEA 0183 and Raymarine SeaTalk1 input devices, while also featuring an NMEA 0183 output.
See the table below for inputs and outputs of both the A034(discontinued) and A034-B to help you select the right option.
The A034B gives you:
- NMEA 2000 to WiFi and USB, 2-way communication
- 2-way WiFi and USB gives you control and data inputs from WiFi and USB devices
- Additional allows adding three NMEA 0813 inputs and a SeaTalk1 bus input into the data stream
- NMEA 0183 output
- Filtering options
- Routing options
-
Convenient combined marine data over ,
- WiFi on your mobile devices
- USB to PC and
- NMEA 2000 to listener devices including displays, chart plotter and autopilots
- NMEA 0183 to listener devices
Typical System Setup
The A034B is a flexible device and the connections can be tailored to your individual setup.
Below is an example setup. Whether you input devices (eg.GPS, AIS, wind. depth and other sensors) are SeaTalk1, NMEA 0183 or NMEA 2000, simply connect them to the correct input connection.
The A034B can be used out of the box for standard functionality or configured for additional sophistication.
Without Configuration: The multiplexer converts and combines data received on the listener ports and sends this data to NMEA 2000, NMEA 0183 WiFi and USB simultaneously. Default Baud rates: NMEA input 1 and 2: 4800bps and NMEA input 3: 38400bps
With Configuration:
- Configurable NMEA Baud rates
- Linking to a second onboard WiFi network if desired
- USB troubleshooting input function
- Filtering options, each input has a flexible filter that can be configured to pass or block specific sentences. This helps to avoid conflict if 2 input devices are inputting the same data type (eg GPS), and frees up bandwidth, significantly reducing the possibility of data overflow and the resulting loss of data.
- Routing options, the powerful routing feature allows the NMEA, SeaTalk and WiFi input data to be routed from any input to specific outputs.
WiFi Connection
The WiFi module is set for direct Ad-hoc WiFi connection as default, with no need for a router. The SSID and password can be changed through QK-A034B configuration software, increasing security and memorability.
Up to 4 wireless devices can connect directly to the A034Bin Ad-hoc mode.
QK-A034B can also be connected via Station mode using the Configuration software. This allows for greater range and remote access, as well as additional multi-device access.
The WiFi can also be disabled and be placed on Standby mode if desired.
Bi-directional WiFi: With 2-way WiFi, the A034B allows for wireless connection to autopilots and other NMEA devices, giving you the freedom to navigate, monitor and control from your iPad, iPhone, Android tablets and other WiFi enabled devices.
Bi-directional USB: 2-way USB the A034B allows the user to send instructions and data through USB from a laptop to all connected outputs. Frequently used to control autopilots and other NMEA devices from OpenCPN and other PC software, allowing the user to navigate, monitor and control from your laptop. This feature also allows for sending of test data for system testing and analysis.
Technical Specifications & Features

FAQ – Will I need a Protocol bridge to connect NMEA 0183 devices? The answer is probably not…
This product uses the NMEA 0183-RS422 protocol (differential signal), however, some older chart plotters or instruments may use the older NMEA-RS232 protocol (Single-ended signal).
To ensure A034B compatibility with older style NMEA0183 devices, we provide the QK-AS03 Protocol Bridge. Check if your device uses NMEA0183 RS422(differential) or RS232 (single-ended) NMEA 0183.
- NMEA0183 RS422 (differential) devices’ wiring is compatible ‘out of the box’.
- NMEA0183 RS232 (single-ended) devices will require a Protocol Bridge (AS03) to connect your wiring.
Connecting the A034B to an older (RS232) instrument or Chartplotter is not a problem, simply use the QK-AS03 Protocol Bridge. This connects NMEA-RS232 wiring to MNEA0183-RS422 and vice versa, using a simple ‘Plug ‘n’ Play’ connection, with no setup or configuration needed.
You will probably need an AS03 if you are connecting to an older Garmin, Raymarine or Standard Horizon device. The easiest way to check, is to look at the input/output connections on the device that you will connect the multiplexer to. If your NMEA 0183 data wire input/output connections has a TX, RX or GND connection, use a Protocol bridge.
