Abstract of the Disclosure A utility usage data and event data acquisition system incorporating improved means for acquiring input serial data messages representing the amount of consumed utility services and/or binary event data from one or several external sources, the system also incorporating means for reformating the input data and appending an identification code and an error detection code to the acquired data, and means for transmitting messages comprising the identification code, the acquired data, the error detection code and other control information to a central location through the agency of coaxial cables, public switched telephone networks or other transmission facilities utilizing data terminals which accept serial binary messages at logic level voltages. Data message transmission is initiated either at random times by an algorithm within the control program of a microprocessor incorporated in the system or from an externally applied command signal.
