2.4. NMEA 2000 Port
The A034 converter provides a NMEA 2000 network connection. The A034 combines all the NMEA
0183 data inputs and then converter them to be NMEA 2000 PGNs and visa-versa. With A034, WiFi
data, USB data and NMEA 0183 input and SeaTalk1 input data can be available on new NMEA 2000
capable instruments, such as NMEA 200 chart plotters.
The A034 requires power from a NMEA 2000 backbone.
NMEA 2000 network must at least consist of, a powered backbone with two terminators (termination
resistors), to which the multiplexer and any other NMEA 2000 devices must be connected.
Each NMEA 2000 device connects to the backbone. It is not possible to simply connect two NMEA
2000 devices directly together.
A034 is supplied with a spurred five-core screened cable for the NMEA 2000 connection, fitted with a
male micro-fit connector. Simply connect the cable to the network backbone.
2.5. Conversion Lists
The following tables lists the supported NMEA 2000 PGN’s (parameter group numbers) and NMEA
0183 sentences. It is important to check the table to confirm that the A034 will convert the
sentences/PGNs required.
Through USB and WiFi the A034 will output in NMEA 0183 format, including all NMEA 0183 messages
received and NMEA 0183 messages converted from the NMEA 2000 network.
WiFi/USB inputs are NMEA 0183 messages and are converted to NMEA 2000 for the NMEA 2000 bus.
The following is a typical PCDIN message format outputted through WiFi and USB. The chart software
will convert this into more meaningful information.
