ONNECTIONS
2.1 SeaTalk
The built-in SeaTalk1 to NMEA converter translates SeaTalk data into NMEA sentences. The
SeaTalk port has 3-Pin terminals for connection to the SeaTalk bus. Make sure the
connection is correct before powering up. A wrong connection could damage the QK-A031 and
other devices on the SeaTalk Bus.
When a SeaTalk message is received, QK-A031 checks if the message is recognised and
should be processed. When the message is recognized by the SeaTalk messages table, the
message is extracted, stored and converted to an NMEA sentence. Any unknown datagram is
ignored. These converted NMEA messages are then combined with NMEA data received on
the other inputs. This function allows a SeaTalk instrument to communicate on an NMEA
network. Only one SeaTalk input is needed since the SeaTalk bus is a single-cable system that
connects all the instruments together through one cable. SeaTalk to NMEA converter in the
QK-A031 works in one direction only. No NMEA sentences are converted into SeaTalk, the
multiplexer just listens on the SeaTalk bus.
