Grey Posted May 25, 2012 Report Share Posted May 25, 2012 CAN Devices are DAQ devices or they do something else? Anybody can help me. I have seen USB8473 High speed can module. need to know more info about it general CAN devices functionality. thanks Quote Link to comment

I have seen USB8473 High speed can module. need to know more info about it general CAN devices functionality. thanks A CAN device can be just about anything. In Cars/Trucks - CAN devices are generally the different controllers; ECU, ABS etc. But if you look at automation HW from Beckhoff, you'll find CAN devices that are more like DAQ devices. /J Quote Link to comment

I have seen USB8473 High speed can module. need to know more info about it general CAN devices functionality. thanks CAN is a communication protocol. Think of it like a Serial port (RS-232). For it to work you need a device that also speaks the same language (communication protocol). It is different from DAQ which measures (or outputs) a real world signal. A DAQ device can read voltage between two points. A CAN device can read CAN messages. If you don't have a device to talk to that can speak CAN, then the USB 8473 device will be useful to you.

I have seen USB8473 High speed can module. need to know more info about it general CAN devices functionality. thanks CAN is merely a communications interface like ethernet, RS232, RS 422, STANAG 1553 etc. The USB8473 is a converter to enable you to connect to a device that has a CAN interface via the USB port of your computer.

TomOrr0W Posted May 25, 2012 Report Share Posted May 25, 2012 If your application does end up communicating with CAN devices, note that NI's USB-8473 devices do not support NI-CAN's Channel API (you would need to use the Frame API or the Frame to Channel Conversion method, which are both somewhat more complicated -- See the LabVIEW help for NI-CAN).

Saverio Posted May 29, 2012 Report Share Posted May 29, 2012 (edited) Nobody has mentioned the Wikipedia entry: http://en.wikipedia.org/wiki/CAN_bus, which is the first place I would have gone to get a basic understanding of what CAN is. Edited May 29, 2012 by Saverio 1 Quote Link to comment
