8.3.1. Will your device need a driver?
Windows:
To enable the USB data connection of A028 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
The A028 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 A028 will be recognized and shown as a USB modem. The ID can be checked
with the following steps:
1. Plug the A028 into a USB port and launch Terminal.app.
2. Type: less /dev/*sub*
3. The Mac system will return a list of USB devices. A028 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, A028 will show up as a USB
CDC device on /dev/ttyACM0.
8.3.2. 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 A028 can be found in Windows ‘Control Panel-
>System->Device Manager’ under ‘Ports (COM & LPT)’. Find the A028
in the list for the USB variant. To change this number, double click the
A028 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
.
