ABSTRACT:
A transceiver inserted between a source of binary signals and a one-wire line, dialoguing with a similar transceiver in series with another source at the opposite end of the line, comprises two voltage sensors connected in parallel to the line at a point downstream of a terminal impedance at which the line voltage substantially equals the mean of the voltage levels simultaneously generated by the two sources. The two voltage sensors have thresholds respectively lying at a lower and an upper intermediate level between the two binary signal levels (L, H) employed and work into a common signal receiver through a multiplexer so controlled by the local source as to connect that receiver always to that detector whose low or high output signal corresponds to the binary value (L, H) of the signal then arriving from the remote source.
