SERIAL DEVICE CIRCUIT

PROBLEM TO BE SOLVED: To provide a serial device circuit for enabling an establishment of the communication of a plurality of devices each having the same serial I/F with all connection devices by one I/F. SOLUTION: In the figure, a function block diagram as one example of this serial device circuit is shown. The serial device circuit comprises: the devices 1 each having the serial I/F; a controller 2 communicating with the devices 1; and a control device 3 present between signal lines connecting the devices 1 and the controller 2, and performing communication control with the plurality of devices 1. By interposing a device such as a PLD (Programmable Logic Device) or an FPGA (Field Programmable Gate Array) between the controller and the devices, the controller can easily establish the communication with the plurality of devices by one I/F.
