ABSTRACT:
The invention relates to a system for coupling a mobile data input unit to a field bus, whereby a coupling unit is connected to the field bus via a spur line and a line driver and the signals at the output of the line driver are supplied to a coupling link or received from the latter via first level converters. The mobile data input unit receives the signals from the coupling link or supplies them to the latter via second level converters.
