In the highly interference-prone environment of an active electrosurgical unit (11), but also in waterjet, argon plasma and cryosurgical devices secure data transmission is ensured. Preferably, a differential transmission technique is selected in which one or more pairs of lines (wires 22, 23) are used, of which one of the conductors transmits the signal and the other the inverted signal. By subtracting the two signals, the actual data signal is obtained on the receiver side. If disturbances from the environment interfere with the data transmission path, ie the line, this is done to the same extent because of the spatial proximity and possibly twisting of the two lines. Due to the subtraction made at the respective receivers, the disturbances in the signal cancel each other out. |
