The Mac system will return a list of USB devices. A026+ will display as -
“/dev/tty.usbmodemXYZ”
where XYZ is a number. Nothing further needs to be done if it is listed.
Windows 7,8,10:
The drivers usually install automatically if your device is running an original Windows 10 version. A new
COM port will automatically show up in the device manager once powered and connected via USB.
The A026+ registers itself to the computer as a virtual serial com port.
If the driver does not install automatically, it can be found on the included CD and downloaded from
www.quark-elec.com.
Linux:
No driver required. When plugged into the computer, the A026+ will show up as a USB CDC device on
/dev/ttyACM0.
Checking the USB connection (Windows)
After the driver is installed (if needed), run the Device Manager and check the
COM (port) number
. The
port number is the number assigned to an input device. These can be generated randomly by your
computer.
Your chart software may require your COM port number in order to access the data.
The port number for the A026+
can be found in Windows ‘Control Panel>System>Device Manager’
under ‘Ports (COM & LPT)’. Find something similar to ‘STMicroelectronics Virtual Com Port’ in the list for
the USB port. If the port number needs to be changed for some reason, double click the A026+ and
select the ‘Port Settings’ tab. Click the ‘Advanced’ button and change the port number to the one
required.

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 use a terminal monitor application, first connect A026+ to the computer, follow the instructions to
install the driver if required. After the driver is installed, run the Device Manager and check the COM
(Port) number.
