Abstract

A method is performed to collect information in a machine including an on-board data link connecting a wireless device and at least one on-board module. The process includes providing a first operational mode for the wireless device that allows the wireless device to perform a first set of operations on data associated with the at least one on-board module and providing a second operational mode for the wireless device that allows the wireless device to perform a second set of operations on the data associated with the at least one on-board module, wherein the second set of operations is a subset of the first set of operations. The process also determines an operational mode for the wireless device based on predetermined criteria and configures the wireless device based on the determined operational mode. Further, the process includes operating the wireless device in either the first or second operational mode based on the configuring.
