Onscreen display and data logging with rs232-usb connection

[tramp094]

I need to get onscreen display and user interfaces using labview and data logging in excel.

Different sensors like RTD,Barometer,RH sensor,Proximity sensor with rs232 outputs are to be connected to the computer using rs232-usb cables

and usb hub. 

As im new to this and moreover instrumentation is not my field,its very confusing for me to understand all these.

So someone please explain the steps in details to execute this work with prev discussion thread links or youtube links to get a clear picture

Thanks in advance...

NI-VISA is the LabVIEW driver for communicating with RS-232 instruments. I suggest you take a look at the examples which are built into LabVIEW. Go to 'help' -> 'find examples...' and type in VISA and you will get lots of examples which you can use to try to communicate with one of your devices. You will need to know the format of the commands/responses from each device (from the manufacturer datasheet).

If you are new to LabVIEW - there are lots of free tutorials/training available - I suggest you spend a few hours going through some of the basic introductions and then come back when you have more specific questions and/or some code to show us.
