ARINC 429 Communication Link

This example shows a communication link that follows the ARINC 429 specification. Here it is configured for 100kBits per second operation. The ARINC 429 specification is for a simplex broadcast bus with odd parity checking. The cable is a balanced line comprising a twisted pair for data wires A and B, plus an outer shield. This model can be used to check compliance with the ARINC 429 specification, and to assess the impact of different cable lengths, cable parameters and abstracted transmitter and receiver characteristics. It can also be used to check operation with multiple receivers, the ARINC 429 specification allowing for up to 20 receivers to connect to a single transmitter.
