Abstract
A multiplex system includes a bus, a central controller coupled to the bus, and a number of remote stations coupled to the bus. The central controller applies clock signals to the bus, receives data signals from the bus, and applies data signals to the bus. The remote stations each maintain a respective count of clock signals and exchange data signals with the bus during respective time periods corresponding to respective counts. The controller operates to detect a failure of the bus and then to prevent clock signals from being carried to the remote stations associated with the failed bus. In this way, erratic operation of the remote stations is minimized.
