ARINC825 Cards

ARINC825 (CAN bus) Modules with a Difference


AIM’s ARINC825 cards can work either with full functionality as an active CAN node for testing and simulating or in listening only mode for monitoring and recording purposes of Avionic CAN bus (ARINC825) applications on up to 4 electrically isolated CAN bus nodes concurrently. All nodes are in conformance with the ISO11898-1/-2 standard. They are accessible by software separately and can be used as 4 independent CAN bus nodes. An onboard IRIG-B time decoder allows users to accurately synchronize single or multiple modules to a common time source. All supported signals are available through front I/O and rear I/O interface. ARINC825 cards consist of FPGA based CAN interface controllers as well as a FPGA based 32-bit microcontroller core and a separate processor for IRIG-B synchronization with high resolution time stamping. All nodes are operating concurrently at CAN bus high speed bit rate of up to 1Mbit/s with the intelligence to process scheduling of CAN frames in real time onboard to significantly off-load the host processor.
For embedded applications the AMC825-4 PMC module is available in a conduction cooled version. Using AIM’s family of PCI, CPCI (3U and 6U) and VMEbus carrier cards for PMC our clients have off the shelf solutions in a broad range of card formats.
ARINC825 (CAN bus) modules are delivered with an Application Programming Interface (API) and Driver Software compatible with Windows, Linux and VxWorks.
An ARINC825 Resource Component is available for AIM’s™ databus test and analysis tool including Tx and Rx simulation capabilities, a Chronological Bus Monitor and support for decoding of payload data within CAN messages. This allows to implement a powerful ARINC825 (CAN bus) analyzer or a complete test system in conjunction with other AIM avionics databus interfaces and™ supported 3rd party hardware.
