1. Introduction
The sophisticated QK-A033 NMEA multiplexer combines data from multiple NMEA, SeaTalk, WiFi and
USB devices.
The A033 call be used out of the box for standard functionality or configured for additional
sophistication.
Through advanced filtering and routing, the A033 NMEA enables controlled routing of data to specific
outputs, blocking of excess data and overflow reduction.
The A033 multiplexer has three NMEA 0183
inputs (listener-ports), one SeaTalk1 input, two
NMEA 0183 outputs (talker-ports), a WiFi
interface and USB port to connect to host
devices such as PCs, laptops or tablets.
The internal SeaTalk converter allows the A033 to listen on the SeaTalk bus and convert SeaTalk
data to NMEA messages.
Standard Functionality:
The multiplexer converts and combines data received on the listener ports
and sends this data to all talker ports, WiFi interface and USB simultaneously.
Routing options:
The powerful routing feature allows the NMEA, SeaTalk and WiFi input data to be
routed from any input to specific outputs.
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.
Bi-directional WiFi:
2 way WiFi and USB connectivity, the A033 allows for wireless connection to
autopilots and other NMEA devices if desired.
Data from multiple instruments is available wirelessly though WiFi connections, giving complete
freedom to navigate, monitor and control from anywhere on board. Up to 4 iPads, iPhone, Android
phones and tablets or other WiFi enabled devices can connect directly to the A033 with no need for
an additional access point.
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. The USB port is also
used for configuration of specific WiFi and NMEA ports settings.
