Check the LED lights
. LEDs indicate power (LED8), NMEA In (LED 2, LED 3, LED 4), NMEA out
(LED 5) and SeaTalk (LED 1) status respectively. LED6 & LED7 are not used on this model.
Configure
with GUI Configuration APP. Ensure all other APPs and programs are closed before
using the GUI.
CONNECTIONS
QK-A031 has the following electrical connections/indicators:
SeaTalk input connector
. The SeaTalk port has 3-Pin terminals for connection to the SeaTalk bus,
i.e.
(+, D, - ).
Ensure the connection is correct before powering up
. An incorrect connection could damage
the QK-A031 and other devices on the SeaTalk Bus. This connection is uni-directional, the multiplexer
listens on the SeaTalk bus and integrates the messages with AIS and GPS for output via WiFi, NMEA
output or USB connection. A list of recognised messages is available on the application notes.
* Seatalk™ is a family of proprietary maritime communications protocols developed by Raymarine
NMEA input
. QK-A031 has three NMEA inputs called IN1 to IN3. Each input should be connected to
one output only. These inputs are galvanically isolated from QK-A031 multiplexer, as specified by the
NMEA 0183 standard. QK-A031 performs serial combining of these three NMEA-0183 serial inputs into
one NMEA-0183 serial output. Input baud rates are switch selectable through the GUI Configuration
APP. The default baud rate of the NMEA 0183 inputs is 4800 bps (NMEA standard) but it can be set to
any value from 4800 to 38400 bps.
NMEA 0183 output
. The NMEA 0183 Out is capable of driving the combined data from the inputs. The
default baud rate is 4800bps, however it can be set to from 4800 to 38400bps using the configuration
APP. Connect the + and - terminals of the NMEA output on the QK-A031 to the + and - terminals of the
