Abstract
The switch input processing module has: a control unit; a first external connection terminal to which either an analog signal of an analog signal system or a serial signal of a serial signal system is supplied; an analog signal transmission and serial signal transmission line which is disposed between the first external connection terminal and the control unit; and a second external connection terminal to which a determination signal indicating that either the analog signal system or the serial signal system is connected to the first external connection terminal is supplied. When the control unit determines that the determination signal indicates connection of the serial signal system, the control unit makes the serial signal transmission line conductive. When the control unit determines that the determination signal indicates connection of the analog signal system, the control unit makes the serial signal transmission line nonconductive.
