BMC Communications Corp. is pleased to introduce the first of its kind, the Universal Avionics Digital Interface (UADI), a plug-and-run device. The device uses a powerful 16-bit RISC low-power microcontroller, which allows firmware programming in the field through a computer.


The UADI supports a wide variety of communication protocols: MIL-STD-1553 dual redundant interface, ARINC 708/453, up to TWO ARINC two-wire PROTOCOLS such as 429/575/572/ 582/615/etc, and up to TWO RS-232 and ONE ARINC 573/717. The device also includes 8 analog inputs with 12-bit resolution8 general I/O with upgradeable capabilities.


The 1553 operates from a single 5-20 Volt supply. A variety of the SBC includes a voltage converter from input voltage from 18-36Volts.

A variety of applications like error injection-detection, sub-address selection, Major/Minor cycle frame, long loop test, etc can be easily implemented using BMC libraries. The unit operates as BC, RT or BM.

The SBC-UADI is an extremely low power device, conduction-cooled with RF protection. A DC/DC DC power converter with  voltage input range from 18 V to 36 V and it small size  make it  a perfect solution for  avionic applications.

Board  is available in Commercial or Industrial ruggedized extended temperature grades.

     Conduction-cooled with RF protection.
