Abstract
Different type devices coupled at random to different channels of a controller therefor, are identified and initial conditions are set by successively comparing known identification codes provided by the controller for known devices with the unknown identification code received from the device whose channel is enabled. In response to positive comparison the identity of the device is known and the controller provides a stored record of such identity and further enables device type specific operations to be provided by the controller.
