Hello! Prompt, please, what changes for work with Win 8.1 are necessary?
P.S. For PCSGU 250
No need for any special changes.
Just download and install the driver “Driver for Microsoft Windows 8” from:
velleman.eu/support/download … U250&type=
Here you can download the instructions how to install the driver: box.com/s/vh9olqyx3idhhxn8ujwm
(The instructions are for Windows 7 but applicable for Windows 8.)
