Installation
I downloaded the ZIP version from http://www.harduino.ru/index.php/ru/skachat. I let Google Chrome handle the translation.
The EXE wouldn’t download onto a Windows computer, so the ZIP version was necessary. During the installation process, you will have to identify a COM port to the installer.
The one saying CH340 is the one to select when asked for a COM port, in my case COM-9.
When the USB cable is ready, power off the ATS25 and power it back on while pressing the encoder wheel in. If it displays WELCOME, click the encoder wheel.
