Need to consolidate all your marine data?
The A031 combines up to 3 NMEA inputs with a Seatalk bus…
An effective way to view all your marine data combined wirelessly anywhere on your boat to your mobile phones, tablet and laptop (with the added option to connect to a NMEA chart plotter).
QK-A031 NMEA 0183 multiplexer enables the connection of multiple NMEA 0183 devices and host devices such as phones, chart plotters, PCs, laptops and 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 host devices.
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 can also be used for configuration of specific WiFi and NMEA port settings.
The built-in SeaTalk™ to NMEA converter translates SeaTalk data into NMEA sentences. This data is then combined with NMEA data received on the other inputs. SeaTalk is converted into NMEA sentences but not vice-versa. The SeaTalk bus is a single-cable system and connects all instruments serially. Only one SeaTalk input is needed.
Every NMEA input on the QK-A031 is galvanically isolated, also called opto-isolation. Galvanically isolated input prevents unwanted currents flowing between the instruments and the multiplexer (This prevents equipment damage and interference with radio signals).
QK-A031 has the following electrical connections/indicators:
This product uses the NMEA 0183-RS422 protocol (differential signal), however some older chart plotters or instruments may use the older NMEA-RS232 protocol (Single-ended signal).
To ensure A031 compatibility with any older NMEA0183 device, check if your device uses NMEA0183 RS422 or RS232
Connecting the A031 to an older (RS232) instrument or chartplotter is not a problem, simply order the QK-AS03 Protocol Bridge. Our QK-AS03 Protocol Bridge Connects NMEA-RS232 wiring to MNEA0183-RS422 and vice versa, using a simple ‘Plug ‘n’ Play’ connection, with no setup or configuration needed.
You will probably need an AS03 if you are connecting to an older Garmin, Raymarine or Standard Horizon device. The easiest way to check, is to look at the input/output connections on the device that you will connect the multiplexer to. If the input/output connections on your device (Chart plotter, depth reader, etc.) have a TX, RX or GND connection, use a protocol bridge.
