4. Connecting via USB port
AT011 is supplied with a USB connector. This connector provides power supply and data input for
configuration. This USB connector can be linked directly to a USB port on the PC.
Windows:
To enable the USB data connection of AT011 to other devices, related hardware drivers
may be needed dependent on your system requirements.
Windows 7,8,10
the driver can be found on the CD in the packing box or be downloaded from
https://www.quark-elec.com
The AT011 registers itself to the computer as a virtual serial com port.
The drivers usually install automatically to your device if it is running an original Windows 10 version.
A new COM port will automatically show up in the device manager after plug in.
Mac:
For Mac OS X, the AT011 will be recognized and shown as a USB modem. The ID can be
checked with the following steps:
1. Plug the AT011 into a USB port and launch Terminal.app.
2. Type: less /dev/*sub*
3. The Mac system will return a list of USB devices. AT011 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, AT011 will show up as a USB
CDC device on /dev/ttyACM0.

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 you are using. The port number is the number that Windows assigns as
an input device. These can be generated randomly by
your computer). Your chart software may require your
COM number in order to access the data.
The port number for the AT011 can be found in
Windows ‘Control Panel->System->Device Manager’
under ‘Ports (COM & LPT)’. Find the AT011 in the list
for the USB variant. To change this number, double
click the AT011
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
