An adapter suitable for installation in a machine in place of a customer replaceable unit monitor having a first interface format is described herein. Upon installation of the adapter in the machine, the adapter enables data communication between the machine and a customer replaceable unit monitor having a second interface format that is different than the first interface format. The first and second interface formats may include one or more of: configuration of an electrical interface of the customer replaceable unit monitor, configuration of a mechanical interface of the customer replaceable unit monitor, and configuration of data input to and output from the customer replaceable unit monitor. The adapter may be attached to a module before the module is installed in the machine to simplify installation of the adapter. The adapter may remain attached to the machine when the module is removed from the machine to allow the machine to communicate with other customer replaceable unit monitors having the second interface format. The second customer replaceable unit monitor may include a microprocessor and non-volatile memory disposed in a common package.
