Device for the transmission of signals

The invention relates to a device for the transmission of power supply signals and data signals between a position measuring device (10) and follower electronics (100), wherein the position measuring device (10) has two power supply terminals and two data transmission terminals for bidirectional, differential data transmission and the transmission of the power supply signals and the data signals over a main transmission path in the form of a mixed signal over a single line pair (25), wherein the device comprises a 4/2 line converter (20) which, on the measuring device side, has two power supply terminals and two data transmission terminals, which can be connected to the corresponding terminals of the position measuring device (10), and to which the mixed signal is fed by the follower electronics (100), and which is configured to remove the power supply signals and those data signals which enter from the follower electronics (100) in the 4/2-wire converter (20) from the mixed signal and to output said signals
