USB CAN Adapter CPC-USB/embedded


CAN Bus USB adapter. Galvanic Isolation. Windows & Linux support.

SKU: WU-10-08-241-20 Categories: ,

The CPC-USB/embedded is a USB CAN Bus adapter, for use with Windows or Linux based systems in commercial and industrial environments. It is ideally suited to space constrained applications in embedded PC environments, due to its small size.

The CPC-USB/embedded 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 are optionally available.

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:

2CAN_LCAN data line (dominant low)
7CAN_HCAN data line (dominant high)

Limiting Values
