The Bus Adapter Unit (BAU) is an avionics interface computer which allows ARINC 429 hardware to be used in a MIL-STD-1553B environment. The BAU takes ARINC 429 data and discrete signal inputs and converts them to MIL-STD-1553B. It also receives MIL-STD-1553B data and converts it to ARINC 429 data. The BAU is housed in an ARINC 600, 3 MCU chassis for ease of installation and is already qualified for rugged military environments.
The software contained in the BAU is verified to DO-178B Level A, which makes it capable of handling flight critical data. The unit acts as a remote terminal to transmit and receive over a dual redundant MIL-STD-1553B Data Bus. These computers can be configured via the MIL-STD-1553B bus for a variety of operating configurations, providing flexibility in data handling characteristics and ARINC 429 bus speeds.
