Abstract
An audit system for a vending machine system is provided. This audit system is configured to retrieve operational data, such as a DEX file, from a vending machine controller in the vending machine system. The audit system is further configured to store a communications log of the data transmitted between the vending machine controller and the audit system. This communications log can be used by an operator at a host system to assist in debugging communication errors between the audit system and the vending machine controller.
