Introduction
The QK-A034 is a sophisticated NMEA 2000 to WiFi and USB multiplexer, with added flexibility for your
growing system.
In addition to bi-directional NMEA 2000 to WiFI and USB, the A034 provides a seamless connection of
NMEA 0183 and Raymarine SeaTalk1 input devices to your NMEA 2000 network, WiFi and USB
devices. The internal SeaTalk converter allows the A034 to listen on the SeaTalk bus and convert
SeaTalk data to NMEA 0183 and then NMEA 2000 messages.
The A034 multiplexer has three NMEA 0183 inputs (listener-ports), one SeaTalk

input, a bi-directional
NMEA 2000 output port, bi-directional WiFi and bidirectional USB port.

The A034 can be used out of the box for standard functionality or configured for additional
sophistication.
Through advanced filtering and routing options, the A034 allows controlled filtering of data input,
blocking of unwanted data and routing for data management and overflow reduction.
Default Standard Functionality:
The multiplexer converts and combines data received on the listener
portsand sends this data to NMEA 2000 output port, WiFi interface and USB.
•
Bi-directional WiFi:
the A033 allows for wireless connection to
autopilots and other NMEA devices if desired. Data from instruments is available wirelessly
though WiFi connections, giving complete freedom to navigate, monitor and control from
anywhere on board. Up to 4 connections from iPads, iPhone, Android phones and tablets or
other WiFi enabled devices can connect directly to the A033 with no need for a WiFi access
point. (Thought it can also be connected to an access point/router if desires (see WiFi section)
•
Bi-directional USB:
The USB port also supports bi-directional communications. It allows a
computer-based, navigation applications to send sentences through the multiplexer to control
an autopilot and other devices. The USB port is also used for configuration of specific WiFi and
NMEA ports settings.
Additional Configurable Functionality (through Windows software via USB):
•
Additional WiFi options.
•
Filtering options:
Each input also has a flexible filter that can be configured to pass or block
specific sentences. This frees up bandwidth, significantly reducing the possibility of data
overflow and 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.
