I read about RS232 communication. I have a one end PC which is DTE and at other end is the Data acquisition unit. I want to make communication between this two. But I am not getting clear idea about by which software will PC communicate with Data acquisition unit.

Thank you in advance

 

We can't help you without more information. (it is like the question; how long is a rope?)
Type of pc, data acquisition device operating systems and OSI layers and their protocols used.

PC is windows 7, Data acquisition device is NI-DAQ USB 6525

 

The manual says "Software support for the USB-6525 for Windows 2000/XP is provided by
NI-DAQmx."

The manual also says "The NI USB-6525 is a full-speed USB 2.0 device that provides..." The device does not make use of RS-232.

Did you intend to mention a different device?

Does that instrument have an RS232 output? Can you post its specs and/or manual?

 

DickCappels is correct. use the software at win7 in xp compatibility mode.

Yes the device has RS232 output.

 

Yes the device has RS232 output.

So all you need is an RS232 port in your PC/laptop or whatever.

RS232 is only a standard that defines electronic levels/voltages in a serial communications wiring. But it does not define a protocol. That depends on each device and/or design. For us to know more, you need to post the user/hardware manual of whatever it is that you're trying to communicate with.

 

This the user manual.

The manual you've posted is far from being complete. Either there's another more detailed "hardware manual", or the supplier has its own proprietary (private, and not to be shared) communications protocol. If the latter is the case, I'm afraid that none of us can help you out.
