Abstract

A surgical instrument system can comprise an end effector comprising, one, stored data regarding parameters of the end effector and, two, a stored checksum. The system can further comprise a surgical instrument which can comprise means for ascertaining the stored data and the stored checksum, calculating a calculated checksum using the stored data, and comparing the calculated checksum to the stored checksum, wherein the surgical instrument is configured to generate an error response if the calculated checksum does not match the stored checksum. An end effector can comprise a start bit, stored data regarding the end effector, and an end bit which can be transmitted to the surgical instrument. The surgical instrument can be configured to identify the start bit and the end bit and generate an error response if at least one of the start bit and the end bit are not identified.
