I need to purchase data acquisition software (e.g. LabView, DASYLab) to download data on RS-422. What should I use?

Right now I have the following components in my system:

1. Laptop computer with USB port.
2. Black box containing 56K bytes of data. It has an RS-422 port.
3. USB to RS-422 converter (manufactured by Sealevel).
4. RS-422 cable.

I need to send commands to the black box on the RS-422. And then I need to transfer data from the black box to the computer on the RS-422 and save the data in a binary file.

I need to design a simple user interface to do this. What is the best data acquisition software to do this with?

A long time ago I used a package called “Test Point” by Capital Equipment Corporation. I loved that software, but apparently it is no longer sold. :( I know LabView is the most commonly used data acquisition package, but I have heard the learning curve is substantial. Will DASYLab do what I want? I have heard it is simpler than LabView. Would you recommend something else? Wonderware? Azeotech?

Thank you
 

It seems that LabView has got much bigger community around the Internet - in case of any problems very often you can find very similar question/solution at NI forum.

So the job is only to save the 56k bytes sitting in blackbox to the PC ?
 

Depending on your programming skills you could use Python with TKinter GUI extension to make a simple control panel - the software is for free.
 

There is a open source software called script communicator that can log data to text file, google search for it.
