VCI with one or two galvanically isolated CAN interfaces ac­cor­ding to ISO 11898 on USB 2.0 with integrated dia­gnostic functions

Key Features

  • Rigid aluminium extruded case
  • 1 or 2 galv. isolated CAN interfaces with 1 Mbit/s transfer rate at 90 % bus load
  • Hot Plug and Play for a quick and comfortable start
  • MT-API for development of own applications
  • Optional with error frame detection
  • Ideal for use with a PC or notebook


The device has a fairly rugged housing built of aluminium. Its compact design and resistivity against shock make it very popular in many areas of the  automation and automotive industry.

CAN interfaces
There are either one or two galvanically isolated CAN channels available which comply with ISO 11898-2. The transfer rate ranges up to 1 Mbit/s at 90% bus load.

Flexible data processing
Its USB 2.0 interface enables the CANUSB to be used at any laptop, embedded PC or desktop PC. Once you have installed the driver you will benefit from hot plug and play, which is a connection of device to PC without restart.

Microcontroller and firmware update
The Motorola STAR12 and the Philips PDIUSBD12 guarantee a quick data proces­sing.

Both CAN 2.0 A and CAN 2.0 B are supported. CANUSB is suited for numerous operating systems like  Windows XP, XP embedded, Vista and 7. All firmware updates can be loaded via USB.

Error frame detection
This feature allows surveillance and moni­toring of a CAN network. The CANUSB possesses an own logic for detecting error frames and counting them up in a specific internal memory area. That is used for finding intermittent errors like falsified mes­sages of a CAN participant.

Level measurement
This feature is designed for an analogue meas­ure­ment of CAN levels. It is used for doing diagnostics at vehicles of all kinds or machines. Erratic level indicate for example short circuits. They are often  responsible for data loss.

Programming interface
The CANapi provides all functions for pro­gram­ming own applications. It supports all Sontheim interfaces and several third-party devices which is why we enclose our SiECA132 MT-CANapi with 4 simultaneous han­dles at every interface dongle
