	<p>As explained in [[~~APU-102_Introduction~~\|~~APU-102~~ Introduction]], the APU-102 is the collector of all train data at the site. The APU-102 processes all signals and data from the AEI site external equipment, such as wheel detectors, presence detectors, reader modules, and RF units. As a train passes a site, the APU-102 senses train presence, direction, and speed via the wheel detectors and decodes tag data via the RFID subsystem. It combines the tag and axle data to create a clean consist - a list of all cars and locomotives on the train. Within seconds of the train passing the site, the APU-102 connects and delivers the clean consist list to the host system.</p>		<p>As explained in the [[RailNet AEI System – Introduction\|RailNet AEI System – Introduction]], the APU-102 is the collector of all train data at the site.
