Abstract
Apparatus and method for transmitting signals between a data processing unit and the process stations of an electrostatographic machine. Operating signals from the data processing unit are transmitted in blocks to one or more remote interface units where the signals are stored pending use in controlling the electrostatographic processing stations. A return signal path is provided for two transmitted logic signals as a test of the integrity of the signal transmission. And in addition, a timing device is associated with the remote interface unit or units so that, in the absence of signals occurring within a predetermined period, the remote interface unit will be inactivated.
