Controller Area Network (CAN) is a multicast shared serial bus standard, originally developed in the 1980s for connecting electronic control units (ECUs). CAN was specifically designed to be robust in noisy environments and can utilize a differential balanced line like RS-485. It can be even more robust against noise if twisted pair wire is used. Although initially created for automotive purposes (as a vehicle bus), nowadays it is used in many embedded control applications (e.g., industrial) that may be subject to noise. Bit rates up to 1 Mbit/s are possible at networks length below 40 m. Decreasing the bit rate allows longer network distances (e.g. 250 kbit/s at 250 m).

DNA-CAN Boards are designed to meet the physical and electrical requirements for in-vehicle (automotive) networks based on CAN. Installed in PowerDNA Cube connected to a desktop, industrial, or notebook PC running Windows 2000/NT/XP/Me/9x, you can use DNA-CAN Boards for a variety of CAN applications, including automotive testing and diagnostics, prototype design, factory automation, and machine control.

UEI's CAN interfaces are supported by the powerful UEIDAQ Framework which includes support for all popular operating systems and application languages including LabVIEW and DASYLab.
