ABSTRACT:
A unique vehicle ID number and other verification information is stored in a small memory mounted on a tank truck. When the truck is connected to a loading terminal by means of a cable which is used by an existing overfill/ground system, an interface circuit connected between the memory and the cable prevents signals which are normally found on the cable leads from damaging the memory circuits. When information must be read from the memory, a special identification and verification system connected to the overfill/grounding circuits modifies some of the normal signals on the cable in order to activate the on-board memory and retrieve the stored information without disabling the overfill and ground proving capabilities.
