ACC825-3U-4

Integrated modular solution by using the AMC825-4 PMC cards installed on AIM’s ACC-1 Generic CompactPCI (3U) carrier card.

The ACC825-3U-4 CPCI card 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 4 electrically isolated CAN bus nodes concurrently.

• All nodes are in conformance with the ISO11898-1/-2 standard
• Accessible by software separately and can be used as 4 independent CAN bus nodes
• Object and FIFO modes available to support different application scopes
• Consists 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 1µs resolution time stamping
• All nodes are operating concurrently at software configurable CAN bus speeds from 10kbit/s up to high speed bit rate of 1Mbit/s with the intelligence to process transmit scheduling of CAN frames in real time autonomously to significantly off-load the host processor
• Using AIM’s family of PCIe, PCI, CPCI (3U) and VMEbus carrier cards for PMC our clients have off the shelf solutions in a broad range of card formats

Onboard IRIG-B Time Synchronization
ACC825-3U-4 cards have an onboard IRIG-B time decoder with 1µs resolution and an automatic free-wheeling detection. This allows synchronization of multiple ACC825-3U-4 cards to one common IRIG-B time source for the correlation of data across multiple ARINC825 CAN bus nodes.

Board Software Package – Optional Analyzer Software
The ACC825-3U-4 modules are supplied with an Application Programming Interface (API) and Driver Software compatible with Windows, Linux and VxWorks.
The ACC825-3U-4 module operates with the optional PBA.pro™ Databus Test and Analysis Tool for Windows and Linux.
