System and Method for Monitoring Parameters at a Data Storage Device

摘要

An operational parameter is accessed at a data storage device. The operational parameter is encoded using a serial data protocol. The encoded operational parameter is superimposed on an activity indicator signal outputted by the data storage device. The activity indicator signal is configured to be coupled to a light emitting diode.
