Application note for Quark-elec QK-A024/A026.
QK-A024 is a compact dual channel AIS receiver and is able to receive information from both AIS frequencies simultaneously. It can also combine one external NMEA0813(9.6kbps) input data with GPS and AIS messages. This single data stream is then transmitted via WiFi, USB and RS422 synchronously. QK-A026 includes all of the features of the QK-A024 and also includes an integrated GPS module. Both of them share the same capabilities for most other features; therefore they are covered together in this document.
