Power off all the devices before connecting!
3.1. SeaTalk 1
The built-in SeaTalk 1 to NMEA converter translates SeaTalk data into NMEA sentences. The SeaTalk
port has 3-Pin terminals for connection to the SeaTalk bus. Ensure the connection is correct before
powering up. Inaccurate connection could damage the A033 and other devices on the SeaTalk Bus.
The SeaTalk converter converts the Seatalk messages in the conversion table below. When a
SeaTalk message is received, A033 checks if the message is supported. When the message is
recognized as being on the SeaTalk data table (below), the message is extracted, stored and
converted to an NMEA sentence. Any unsupported datagrams are ignored. These converted NMEA
messages are filtered and then combined with NMEA data received on the other inputs.
This function allows the NMEA multiplexer to listen on the SeaTalk bus. Only one SeaTalk input is
needed since the SeaTalk bus is a single-cable system that connects all the instruments together
through one cable. The SeaTalk to NMEA converter in the A033 works in one direction only. No
NMEA sentences are converted into SeaTalk,
