QK-A031 NMEA 0183 multiplexer enables the connection of multiple NMEA 0183 devices and host devices such as PCs, laptops or tablets. QK-A031 multiplexer has three NMEA 0183 inputs (listener-ports), one SeaTalk1 input, one NMEA 0813 output (talker-port), a WiFi interface and a USB port to connect to a host device. The multiplexer combines NMEA data that is received on the listener ports and sends this data to a talker port, the WiFi interface and the USB port simultaneously. The USB port is also used for configuration of specific WiFi and NMEA ports settings.
The built-in SeaTalk1 to NMEA converter translates SeaTalk data into NMEA sentences. This data is then combined with NMEA data received on the other inputs. This allows a SeaTalk instrument to communicate on the NMEA network. Only one SeaTalk input is provided since the SeaTalk bus is a single-cable system that connects all instruments together through one cable. The SeaTalk to NMEA converter in the QK-A031 works in one direction. NMEA sentences are unable to be converted into SeaTalk, the multiplexer just listens on the SeaTalk bus.
Every NMEA input on the QK-A031 is galvanically isolated (also called opto-isolation).A galvanically isolated input prevents unwanted currents flowing between the instruments and the multiplexer. These currents can damage equipment or interfere with radio signals and should therefore be avoided.
