In an exemplary embodiment, a measurement network at a bedside monitoring station can be sequentially stepped through a series of measurement modes either at a bedside monitoring station or at a central monitoring station. A serial in parallel out shift register has successive active positions corresponding to the successive measurement modes and may be stepped either by means of a local push button switch, or by means of a respective corresponding push button switch at the central station. At the central station, a decade counter and decoder arrangement drives a numerical readout for each local station for the purpose of representing each of the local measurement modes. A series of reset circuits couple the outputs of the first shift register stages of the respective local stations with the reset input of a corresponding decade counter such that each time the associated shift register stage is placed in an active state the counter is placed in an initial count condition. By holding a push button of the central station actuated, pulses are supplied to the corresponding local shift register at a rate of about one pulse per second so as to effect a sequencing of the measurement modes at the local station without further manual operations.
