Abstract
A method and a system for signal transmission between two computers is described, wherein one of the computers is fixedly mounted and the other computer is mounted in a rotational element, such as a plate cylinder of a printing machine. The transmission channel includes a rotational transformer. The rotational transformer utilized to transmit the signals is of single channel design. Data collisions resulting from the simultaneous transmission of messages are avoided through detection by the computers. Accordingly, both computers simultaneously transmit the signals present on the transmission channel during the transmission of a message and compare them with the transmitted signals. If an inequality is determined, the transmission procedure is aborted and restarted after a predetermined period of time.
