USB CAN Bus Adapter

CPC-USB/embedded

The CPC-USB/embedded is a USB CAN Bus adapter, for use with Windows or Linux based systems in commercial and industrial environments. Due to its compact size it is ideally suited to applications in embedded PCs. It is installed directly at a SUB-D9 case opening or a slot panel and wired with the included cable to a pin connector of an internal USB interface of the main board.

ProCANtool CAN-Monitor for Windows is included with purchase; Advanced Network Monitoring, Analysis, and Higher Layer Protocol Tools optionally available.

CAN to USB Interface: CPC-USB/embedded

CPC Software Interface Framework

Supporting Software

As a member of the CPC family of PC to CAN interface products, the CPC-USB/embedded benefits from the CPC Software Interface Framework, which provides a consistent host software interface environment for Windows and Linux based applications that is independent of the PC hardware interface being used.

Included with Purchase

The CPC USB/ARM7 can also be used with SocketCAN in Linux based applications.

Technical Data

Layout and Connection

CPC-USB includes a CAN segment connected by a male plug of type D-Sub 9, the pin assignment is complying to CiA DS-102 standard. In addition, the interface includes a USB connector that also carries the supply for CPC-USB. The following table shows the assignment of the CAN connector:

Pin Name Function
2 CAN_L CAN data line (dominant low)
3 GND Ground
7 CAN_H CAN data line (dominant high)

Limiting Values

Parameter Minimal Maximal Unit
Storage temperature -40 +80 °C
Operating temperature -30 +70 °C
Supply voltage 0 +6 V
Voltage on bus connections -30 +30 V

Any (also temporary) stress in excess of the limiting values may cause permanent damage on CPC-USB and other connected devices. Exposure to limiting conditions for extended periods may affect the reliability and shorten the life cycle of the device.

Nominal Values

Parameter Minimal Typical Maximal Unit
Current consumption - 100 500 mA
Supply voltage 4.0 5.0 5.5 V

All values, unless otherwise specified, refer to a supply voltage of 5V and an environmental temperature of 20°C.
