Data Sheet
Compact Vehicle Interface
Most ECUs in today’s onboard vehicle networks use the CAN bus
as a communication medium for onboard and diagnostic data.
Easy-to-use access from the PC to the CAN bus is required for all
kinds of applications. CANusb is a powerful hardware interface
perfect for use in precisely such cases. The Plug&Play functionality
of the USB interface ensures simple handling. This is of particular
advantage when used in mobile operations.
Areas of Implementation and Applications
In the ECU Engineering, Simulation, Test and Validation sectors,
the CANusb supports a wide range of communication applications. It allows parallel access to several ECUs on one CAN bus
– this is particularly important for diagnostic and test applications. The standard CANusb design enables inexpensive access
to CAN high-speed networks. CANusb-CAR is equipped with
CAN high-speed and CAN low-speed transceivers for use with
all kinds of ECUs. Transceiver switching is controlled by software and thus enables simple and flexible use even with different
applications.
Advantages
CAN APIs
The CAN-API, which is standard for all CAN interfaces from
Softing, provides powerful communication 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 or
DeviceNET-API, are also available.
D-PDU API
The standardized programming interface provides applications
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 upon request.
CANusb
CAN bus USB Interface for
Vehicle Electronics
An Overview of Features
Active card with its own microcontroller
1 CAN bus channel
Standard design with CAN high-speed transceiver
Product variant CANusb-CAR available with an
additional integrated CAN low-speed transceiver,
can be switched via software
Local buffering and preprocessing
High performance, reduces the number of time-critical
tasks the PC has
Scalability
If your application requires more than one CAN bus at any time,
the number of communication channels available at the PC can
quickly be extended. This is simple to organize by combining the
existing CANusb interface with further CAN or EDIC
®
interfaces
from Softing.
Flexibility
Combining CANusb with appropriate API software enables
compact solutions for all kinds of communication applications.
The standardized Softing CAN-L2-API thus supports reliable
CAN communication at Layer2 in a simple way. The optional
D-PDU API software makes communication channels with
higher diagnostic protocols available to applications via the
standardized API and thus relieves the application of standard
tasks.
