Military and Avionic Protocols Overview
ARINC 429
Aircraft Radio Incorporated, or ARINC 429 is an avionic standard often found on commercial and freight aircraft.
Connections consist of twisted pairs carrying balanced differential signaling. Single wire pair connections are
limited to 20 receivers or less. Self-clocking is allowed from the receiver end, eliminating the need for clock data
transmitting.
The standard is maintained by the ARINC Organization. Additional information, including the specification, can
be found at
www.arinc.com/ .
Number of Lines Data rate Synchronous or Asynchronous
1 100 Kb/s or 12.5 Kb/s Asynchronous
MIL-STD-1553
MIL-STD-1553 is a Department of Defense military standard used for defining mechanical, electrical, and
functional serial data bus characteristics. Originally used for fighter aircraft, use of the standard has spread to
spacecraft and civil aircraft applications.
The standard is maintained by the Aerospace branch of the Society of Automotive Engineers www.sae.org/ .
Number of Lines Data rate Synchronous or Asynchronous
1 1 Mb/s Asynchronous
