Method for connecting electronic devices and connecting cable

A method for connecting electronic device wherein, to connect electronic devices by a connecting cable, the method comprises the steps of:

• shielding signal lines of a plurality of connecting cables between one end and the other end thereof, respectively by a first external conductor;
• connecting one end of the respective first external conductors to reference potential of one of said electronic devices;
• shielding the respective first external conductors by a common second external conductor;
• and
• connecting a second external conductor to reference potential of the other of said electronic devices, whereby the reference potential of one electronic device and the reference potential of the other electronic device are coupled through a stray capacity between the first external conductors and the second external conductor.
