Configuration and Connectivity
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. For example, you may wish to
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 A034B configuration software, increasing security and memorability.
Up to 4 wireless devices can connect directly to the A034Bin Ad-hoc mode.
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.

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 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 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.
If in doubt contact us for advice.
