9. Connecting Via USB Port
A032 is supplied with a USB connector. This connector provides data output as standard (multiplexed
information from other instruments will also be sent via these connections). This USB connector can
be linked directly to a USB port on the PC. It can also be connected to other mobile devices via an USB
OTG (On the Go) connection using the supplied cable.
Windows 7, 8, 10: To enable the USB data connection of A032 to other devices, related hardware
drivers may be needed, dependent on the system requirements. The driver can be found on the CD in
the packing box or be downloaded from https://www.quark-elec.com
The drivers usually install automatically to the device if it is running Windows 10 (non-upgraded version).
The A032 registers itself to the computer as a virtual serial com port. A new COM port will automatically
show up in the device manager after plug in.
Mac: For Mac OS X, the A032 will be recognized and shown as a USB modem. The ID can be checked
with the following steps:
1. Plug the A032 into a USB port and launch Terminal.app.
2. Type: less /dev/*sub*
3. The Mac system will return a list of USB devices. A032 will display as - "/dev/tty.usbmodemXYZ"
where XYZ is a number. Nothing further needs to be done if it is listed.
Linux: No driver is required for Linux. When plugged into the computer, A032 will show up as a USB
CDC device on /dev/ttyACM0 or similar.
9.1. Checking the USB connection (Windows)
After the driver is installed, run the Device Manager and check
the COM number (this is the number associated with the USB
port being used. The port number is the number that Windows
assigns as an input device. These can be generated randomly
by the computer). The chart software may require the COM
number in order to access the data.
The port number for the A032 can be found in Windows
'Control Panel->System->Device Manager' under 'Ports (COM
& LPT)'. Find the A032 in the list for the USB variant. To
change this number, double click the A032 and select the 'Port
Settings' tab. Click the 'Advanced' button and change the port
number to the one required.
Checking the USB data flow: If desired, the USB data can
always be checked with a terminal monitor application, like
Putty or HyperTerminal. To do this, enter the following into the
COM port settings: Bits per second: 38400bps, Data bits: 8,
Parity: None, and Stop bits: 1 as shown below using
HyperTerminal on Windows as an example
