RAR15-XMC-FIO Interface

High Density MIL-STD-1553 and ARINC 429 XMC front I/O module



Avionics RAR15-XMC-FIO Module


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 RAR15-XMC-FIO features include independent, software programmable data rates and parity, error detection error injection. All channels operate independently.

MIL-STD-1553 Multi-function Interface

RAR15-XMC-FIO 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 RAR15-XMC-FIO interfaces have all the features of the multi-function versions, with either bus monitor and bus controller or bus monitor and 31 remote terminals.
