SIGNALING SYSTEM ABSTRACT OF THE DISCLOSURE A floor position sensor monitors the movement of an elevator car and provides a first predetermined number of inputs each corresponding to a predetermined floor and connected to a first signal converting circuit providing a second predetermined number of coded outputs less than the first predetermined number in response to an input position signal appearing at one of the first inputs corresponding to the floor where the elevator car is located. Each position indicator is remotely located from the sensor and includes opto-isolating circuits connected to receive the second outputs and provides a third predetermined number of outputs photo-electrically isolated from and in response to the second outputs and connected to a second signal converting circuit providing a fourth predetermined number of coded outputs responsive to the third outputs. The fourth coded outputs are connected to an eight segment display and a nine segment display through driver circuits which selectively connect one or more of the display segments in circuit for energization to selectively display one or more alpha-numeric characters in response to the input position signal. An alternative embodiment provides a display employing script type characters utilizing ten elliptically shaped elongated segments to provide predetermined alpha-numeric characters. 0
