ABSTRACT:
An interface for generating a serial bit stream corresponding to one or more switch settings and transmitting that bit stream to a polling circuit. Four parallel bits representing a setting of a decimal switch are converted to serial bit sequence. This sequence is preceded by a start bit and followed by an extended stop bit. In an embodiment where multiple switches are polled, the data sequence is followed by a switch designating sequence and then the extended stop bit.
