ARINC bus recording and monitoring system


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


ECRIN Systems has enriched and modified a COTS computer integrating two PC104 boards to add filtered 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 standard.

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.


  • Based on COTS calculators
  • ARINC-429 links hardware and software integration
  • Opto-isolation board for Rx lines
  • Adding a filtering stage upstream of the power supply to comply with DO-160


  • ECRIN Systems has demonstrated its ability to develop a semi-rugged industrial computer for a military program with aeronautical constraints such as DO-160 qualification.
  • ECRIN Systems has carried out all the tests requested for DO-160 by the French Authorities.
