Michelvd If you use Windows you need a CH340 driver installed. On a MacOS or Linux machine you do not need drivers. Please check if the switches are pushed really to the end on the dipswitch. Does the powerled come on on the board ? You might have a defective cable. Download links for the driver and schematics and such are in the productpage.
