Instrument interface

[Sahara]

Hello,

I have recently purchased on AINUO instruments make 500VA AC Power source, having RS232 interface. However, they have not supplied software alongwith it. Though, I have some command control given by them as per attached user manual. My question is, How to develop a instrument software alongwith NI Labview for 500VA AC Power source. so that I can see the graph, numerical values which are displayed at instrument level.

Sahara,

Before anyone can answer your question we must know more about your knowledge of LabVIEW, your experience at programming, your experience with this instrument, and more details of what you want the program to do.

It appears that English may not be your native language and it certainly is not the first language of the person who wrote that manual. The result is that understanding the manual may be a challenge.  I recommend that you learn to operate the instrument manually before trying to program remote control for it.  Often instruments have subtle interactions which mean that certain commands which are completely valid separately may not work together.  The manual probably does not specifiy these limitations or may do so in a poorly worded manner.  Experience working with the instrument is very useful in figuring out these issues.

If you are not familiar with LV, start with the online tutorials.  Then look at examples for instrument control and RS-232 communications.

I made a quick mod of an example ...

Seems that this 10min approach hit the checksum 🙂

Enter the command and the address of the unit and click write to send the command.  reading will be done always and will 'blow up' the read string indicator, so this is for testing only !

Since these units provide serious power be shure you know what you are doing. Testing at own risk !!

You can use it as a starting point to check your communication.
