APU825-2

The APU825-2 USB2.0 module 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 2 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 2 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

Onboard IRIG-B Time Synchronization
APU825-2 modules have an onboard IRIG-B time decoder with 1µs resolution and an automatic free-wheeling detection. This allows synchronization of multiple APU825-2 modules 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 APU825-2 modules are supplied with an Application Programming Interface (API) and Driver Software compatible with Windows.
The APU825-2 module operates with the optional PBA.pro™ Databus Test and Analysis Tool for Windows.
