Underlying technologySignal transmissionGround-related signals


The connections for audio, video and some data signals are usually related to the ground potential (asymmetrical). Frequently, the ground of the input or output switch is connected to equipotential bonding or a protective conductor. For the HMIs from R. STAHL HMI Systems GmbH this is the case with all connections.


This inevitably leads to cicon2 ground loops which may cause problems with the signal transmission.
