With devices with serial connection, the control panel's cable serves as a data cable and is used to operate the program.

Connection of KETTLER devices with serial connection directly to the PC or using USB to serial adapter (Install "USB-to-Serial" driver!)
 
Plug the right control panel connector into the KETTLER training device's interface. Either connect the other one directly in series or using the enclosed USB to serial adapter (Install "USB-to-Serial" driver!) to the PC.
 
The enclosed USB cable is not required! KETTLER USB driver does not need to be installed!

You can check the installation of drivers in the operating system's (XP, Vista, WIN7) device manager.
