2.6 USB port
QK-A031 is supplied with a USB connector. This connector provides the NMEA 0813 data
output and the configuration input. This USB connector can be linked directly to a USB port on
the PC or other mobile devices via the supplied cable.
To enable the USB data connection of QK-A031 to other devices, related hardware drivers may
be needed, dependent on system requirements.
For Windows 8, 7, Vista and XP, the driver can be found on the CD in the packing box or can
be downloaded from the Quark-elec website at:

QK-A031 registers itself to the computer as a virtual serial port.
No drivers are required on Windows 10. A new COM port will automatically show up in the
device manager after plug in. QK-A031 don’t support OS X and Linux at this moment.
The USB connection status can always be checked with a terminal monitor application like
Putty or HyperTerminal. Ensure that the COM port is set at 38400bps, 8, N and 1 as shown
below using HyperTerminal on Windows as an example to illustrate this process. Connect QK-
A031 to the computer, follow the instructions to install the driver if required. After the driver is
installed, run the Hardware Manager and check the COM interface number.
