ABSTRACT:
A transmitting device, for transmitting position detector signals, comprises a controller for processing signals on various kinds of data from an object of interest; a position detector that has a magnetic pole detecting portion and which detects position data on the object of interest; an up-down counter that counts in an ascending or descending order on the basis of two-phase output signals that are produced from the position detector in accordance with the change in the position of the object of interest; a converting circuit portion in which both the counter value as produced from the up-down counter or the change in the counter value per unit time and a magnetic pole position detection signal as produced from the magnetic pole detecting portion are converted to a serial signal; and a transmission path for transmitting the serial signal to the controller. Furthermore, a method of transmitting position detector signals with the above-mentioned transmitting device, which comprises: converting position data on an object of interest to a serial signal within a given time; superposing the output of an absolute counter on the serial signal after the output has been converted to a serial signal, the output representing the absolute position of the object of interest; and transmitting the signals in superposition to the control unit along a single channel of transmission path.
