Abstract
A matrix switcher includes a switcher unit having connection switches provided at intersections of input signal lines and output signal lines and a control unit having a main controller and a backup controller. The backup controller operates a Web server program to transfer a setup command to the main controller upon receiving the setup command. The main controller executes: processing of switching a connection relation between the input signal lines and output signal lines in the switcher unit; processing of transferring a switching command to another matrix switcher upon receiving the switching command for another switcher; processing of setting up the matrix switcher upon receiving the setup command for the switcher; and processing of transferring the setup command to another matrix switcher upon receiving the setup command for another switcher.
