In order to meet current and expected future avionics recording requirements, the AMU acquires and processes a diverse mix of signals and supports several digital I/O formats including MIL-STD-1553B, ARINC-429, ARINC-717 and high-speed RS-22. The AMU can also output data to multiple recording devices for dual-combined recorder installations.
The AMU is modular in design and can be configured and upgraded as needed. A maintenance port provides the ability to upload new application software, new configuration tables, exceedance monitoring software, view the maintenance log and run test software. Its unique signal acquisition software allows data I/O processing to be customized to meet the specific needs of the operator, without any need for special interface cards. The user can also set up additional events to monitor avionics, engines, fuel flow and other dynamic and structural components.
