RS 232 read

[Dennis_Knutson]

That's weird. I've had no problem with my usb-rs232 converters and I don't use the VISA Open at all. My memory fails me at the moment as to another fix with flaky converters. I think it had to do with using the Set I/O buffer Size. I'll see if I can track down the thread.

It was the Set I/O Buffer Size and the post is here.

OK, I just read the thread and it sounds very interesting. I will try to provoke my earlier problems again and look, whether setting the buffer size is a solution. But tomorrow, now the late "Tagesschau" is over and the bed is calling.

Hi friends,

Excuse me that I couldn't reply to you because of I wasn't here.

I read the RS 232 port randomly so I can read the data that I want or I don't want. I need the reading the port sencronously according to my app. and entirely.So that I should show you a my application and tell it's details for decide that RS 232 vi is.

If you want I can tell you a details of my application or I will come to Lab View training in England. If you come to there I can tell my app.

Thank you...

Hello friends,

I want to read the line in the data in RS 232 port. Example :

My application sends the data in RS 232 port as :

Serial number : 123456 ---------------->Lİne1

CC holded-------------------------------->Lİne 2

SW version : xxx------------------------>Line 3

I want to read the SW version and I want to take the data to Test Stand.

How can I success this. Could you help me?

Thank you..

Hello behluls,

Once you get the information you are looking for in LabVIEW, you can pass this information back to TestStand, just like you would with any other information you need to use in TestStand.  If you're unsure of how to do this, or if you have questions about how to pass information between TestStand and LV, I would check,  C:\Program Files\National Instruments\TestStand x.x\Doc\Manuals  There are quite a few different manuals in this folder, including UsingLabVIEWwithTestStand.pdf. 

Good luck with your application!

Hello Friends,

I read the RS232 port as array. I coolect all data of RS 232 and I will extract the data I need.

Which function should I use for extract the string data from string array. (I use the labview 6.1)

Could you help me please?

Thanks a lot

Hi behluls,

I hope you are doing well today! You could just use the Index Array.vi from the functions palatte in the block diagram.

Hi Adnan,

Thank you,I hope you well too.

I solve my problem with "Scan from tokens" and "Match string".I built an array after that I built a string structure using the "scan from tokens". End of this process I used the "match string"

It works properly.

Thank you...

Best regards
