CAN-AC2-PCI - CAN Bus PCI Interface for Vehicle Electronics

VCI for communications tasks with CAN-API and D-PDU API

CAN communication interfaces are an inexpensive alternative to diagnostic interfaces. CAN-AC2-PCI and Softing’s standard CAN-API form a powerful hardware interface for communication tasks. Alternatively, the VCI can be operated with the D-PDU API.


Areas of Application

  • ECU engineering
  • Simulation
  • Test/validation


  • Active card with its own microcontroller
  • Local data buffering and preprocessing
  • 2 independent CAN bus channels
  • Additional CAN transceivers via piggybacks
  • Galvanic isolation


The CAN-API, which is standard for all CAN interfaces from Soft ing, provides powerful communicati on mechanisms for CAN applications. Local buffering and preprocessing on the VCI result in high performance and a reduction of time-critical tasks for the PC. Special automation APIs, such as CANopen and DeviceNET-API, are also available.


The standardized programming interface provides applicati ons with powerful multi-channel communication mechanisms with vehicle protocols, such as Diagnostics on CAN (ISO 15765) and UDS (ISO 14229). It also allows integration into diagnostic systems in accordance with ISO 22900 (MVCI). D-PDU API is available as an option.


The CAN-AC2-PCI interface supports two independent CAN bus channels. By combining several CAN-AC2-PCI boards (or even other CAN/EDIC® interfaces), the number of communicati on channels available on the PC system can quickly be adapted to the relevant applicati on.


The galvanic isolati on of PC and vehicle interfaces enables trouble-free operation even in harsh manufacturing environments.
