The Four Bus Data Logger is a compact, rugged and lightweight device, providing capability to capture and record 1553 multiplex bus and cockpit voice data for a wide range of applications.

The Data Logger can be used to monitor aircraft, or other types of systems, to provide recording capability of data traffic. Data is recorded onto 1GB removable flash memory card.

The system is also capable of simultaneously recording audio transmissions of the cockpit crew for the same time period. Data and voice recordings are time-tagged with one milli-second resolution, to enable the rapid retrieval of desired data to a specific date/time in the recording.
