Without the cable, the housings measure 75 x 43 x 22 mm and 87 x 43 x 22 mm respectively; with the cable they weigh 78 g and 83 g, the connection cable is approx. 0.75 m long, and the ingress protection is IP20. The scope of supply includes device drivers for Windows 11 (x64/ARM64), Windows 10 (x64) and Linux, the CAN monitor PCAN-View, the PCAN-Basic programming interface, programming interfaces for standardized protocols from the automotive sector and a manual in PDF format.
Commissioning and service
PCAN-View is used to see the messages of the devices on a CAN line; the step-by-step method is described in our system startup procedure in CANbus systems article. The Windows service tool developed by EHR Elektronik also connects through a PEAK PCAN interface; see CANopen I/O Node for MRS Electronic CAN I/O PLC for details.

User ManualWhich operating systems does the PCAN-USB work with?
The requirements are a computer with Windows 11 (x64/ARM64), Windows 10 (x64) or Linux and a vacant USB port (USB 1.1, USB 2.0 or USB 3.0).
What do the status LED states mean?
When the LED is on there is a connection to the driver of the operating system; slow blinking means a software application is connected to the CAN interface; quick blinking means data is transmitted via the connected CAN bus.
Can several PCAN-USB interfaces be used on one computer?
Yes, several PCAN-USB interfaces can be operated on a single computer at the same time. The supplied PCAN-View program allows the assignment of device IDs to distinguish the CAN interfaces in a software environment.
