Will you need a driver to connect via USB?
To enable the USB data connection of A024/26 to other devices, related hardware drivers may be
needed dependent on your system requirements.
Mac:
No driver required. For Mac OS X, the A024/26 will be recognized and shown as a USB modem. The ID
can be checked with the following steps:
1. Plug the A024/26 into a USB port and launch Terminal.app.
2. Type: Is /dev/*sub*
3. The Mac system will return a list of USB devices. A024/26 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.
A024/26 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, A024/26 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 A024/26 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 need to be changed for some reason, double click the A024/26 and
select the ‘Port Settings’ tab. Click the ‘Advanced’ button and change the port number to the one
required.
