Configuration and Connectivity

Configuration

Without Configuration: The multiplexer converts and combines data received on the listener ports and sends this data to all talker ports, WiFi 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, giving you the freedom to navigate, monitor and control from your iPad, iPhone, Android tablets and other WiFi enabled devices.

Up to 4 devices can connect directly to the A033 wirelessly with no need for an access point.

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 A033 configuration software, increasing security and memorability. Up to 4 wireless devices can connect directly to the A033 in Ad-hoc mode.

A033 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 be placed on standby if desired.

FAQ

FAQ – How to connect NMEA0183 RS422 to older RS232 devices.

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 A033 compatibility with any older NMEA0183 device, check if your device uses NMEA0183 RS422 or RS232

• NMEA0183 RS422 devices’ wiring is compatible ‘out of the box’
• NMEA0183 RS232 will require a Protocol Bridge (AS03) to connect your wiring

.

Connecting the A033 to an older (RS232) instrument or chartplotter is not a problem, simply order the AS03 Protocol Bridge. Our AS03 Protocol Bridge 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 the input/output connections on your device (Chart plotter, depth reader, etc.) have a TX, RX or GND connection, use a protocol bridge.

If in doubt contact us for advice.
