What should I do about ARINC EMI and shielding?
There are a few precautions to protect against electromagnetic interference in applications where this is a concern. ARINC 429 lines are vulnerable to both radiated and conducted EMI. If you are experiencing symptoms of EMI (such as excessive noise) you may want to verify the following:
- Chassis is grounded
- Proper shielding
- Termination of all cables
- Appropriate cable types are used (this is application-dependent)
