ARINC bus recording and monitoring system


The French Naval Aeronautics was looking for a system for monitoring and recording the information flow on the various ARINC buses of the KC135.


ECRIN Systems's solution

ECRIN Systems has expanded and modified a AMPRO fanless computer (this manufacturer was since acquired by ADLINK), integrating two PC104 boards to add screened ARINC-429 lines and a DO-160 power supply board.
For this project, ECRIN Systems has developed the ARINC lines opto-isolation board, the power supply and screening board to comply with DO-160F.

After a successful on-board testing campaign on the KC135, 15 computers of this type were manufactured and delivered to the French Defence Procurement Agency.
