Walkthrough
Once session is started, this demo configures the ARINC 429 port features (speed, parity and internal loopback) and enables SDI discrimination for received labels.
Before starting the transmit / receive cycle, user needs to select the number of words to transmit, the word rate for each ARINC 429 label and enter the ARINC 429 words to send onto the data bus. Once the cycle is executed the port is closed and the session is terminated.
