A429 Schedule


A429 Schedule Label-SDI demo is used to schedule ARINC 429 words transmit / receive cycle with the possibility to select:

  • SDI (Source Destination Identifier) for each ARINC 429 label
  • word rate for each ARINC 429 label

Example below shows how SDI Discrimination is applied on label 0100.

Label 0100 Data (Bits 32-8) SDI (Bits 9-8, extracted from Data)
#0 0x222220 00b
#1 0x333331 01b
#2 0x444442 10b
#3 0x555553 11b


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.
