1. Introduction
The QK-A034-B is a sophisticated bi-directional NMEA 2000, WiFi, USB and NMEA 0183 multiplexer,
with a huge amount of flexibility for your growing system.
It is the perfect solution for merging wired NMEA2000 and NMEA 0183 equipment to each other and to
to USB laptops and tablet WiFi APPs to form a linked-up system.
The A034-B multiplexer has three NMEA 0183 inputs (listener-ports), one SeaTalk
1
input, a bi-
directional NMEA 2000 output port, NMEA 0183 output, bi-directional WiFi and bi-directional USB port.
All NMEA 2000, NMEA 0183, USB and WiFi devices can communicate with each other.
In addition to bi-directional NMEA 2000, WiFi, USB and NMEA 0183, the A034-B provides a connection
to Raymarine SeaTalk
1
input devices to all connected output devices (NMEA 2000, NMEA 0183, WiFi
and USB devices). Specifically, the internal SeaTalk
1
converter allows the A034-B to listen on the
SeaTalk
1
bus and convert SeaTalk
1
data to NMEA 0183, which are in turn converted to NMEA 2000
PNGs.
The A034-B can be used out of the box for standard functionality or configured for additional
sophistication. Through advanced filtering and routing options, the A034-Ballows 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 all inputs
and listeners ports and sends this data to NMEA 2000 output port, NMEA 0183, USB output and WiFi
interface.
•
Bi-directional WiFi:
With 2-way WiFi connectivity, the A034-B 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 A034-B 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
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
including connection to an access point to share marine data across
your entire WiFi network or disabling WiFi output if desired.
•
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.
