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.

Specifications
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.
