ARINC 429 Message Handling

On-board firmware, large data buffers, and a high-level API are integrated to provide total flexibility in monitoring and generating ARINC bus traffic. Simultaneous scheduled and burst mode (FIFO) messaging is supported on all ARINC 429 transmit channels. Each ARINC 429 receive channel provides simultaneous dedicated and buffered mode storage, along with label/SDI filtering.

Three different methods are provided to buffer received messages:

• • Buffered mod­­­­e utilizes a separate circular buffer for each channel.
• • Merged mode combines all received messages into a single, time-sequenced circular buffer
• • Dedicated mode provides a snapshot of the latest message by label or label+SDI

ARINC 429 Architecture
The RAR15XF features include independent, software programmable data rates and parity, error detection error injection. All channels operate independently.

MIL-STD-1553 Multi-function Interface
RAR15XF multi-function interfaces are easily configured to operate with simultaneous bus controller, up to 31 remote terminals and bus monitor functionality.

MIL-STD-1553 Dual-function Interface
Dual-function RAR15XF interfaces have all the features of the multi-function versions, with either bus monitor and bus controller or bus monitor and 31 remote terminals.
