For Multifunction Embedded Boards, the AR429/575 module provides up to six programmable ARINC-429 channels. Each channel is software selectable for transmit or receive, and Hi or Lo speed, for either ARINC429 or 575. The receiver logic converts serial BRZ data stream to a 32-bit wide parallel data word. If Label, SDI and parity bits pass validation then ARINC data word is sent to Receive Output FIFO. Message Data can be sent immediately or buffered for synchronized transmission. In buffer mode ARINC words are read from the TXMIT buffer and sent out at the Txmit Interval Rate. In repeat mode ARINC message data is sent continuously. The user interface supports FIFO buffering and Interrupts. Txmit data can be sent immediately or scheduled. To schedule a Txmit sequence the Txmit FIFO can be loaded with a sequence of up to 256 ARINC data words. The interval of transmission is programmable. Enabling the channel begins transmission. TX and RX data are continuously monitored and verified.
