Error VISA: (BFFF006C) and (BFF006B)

[Deutschrich]

I have already been more than a week researching about my problem and I have got any solution....

I'm working in Labview 2009 with serial communication RS232. I'm not working with adapter USB-RS232 but with a normal cable RS232.

The problem is that I try to read data from my device, it works well for a air of seconds and than the program stops and appears the following error:

Error -1073807252 occurred at VISA Read in Interfaz2.vi

Possible reason(s):

VISA:  (Hex 0xBFFF006C) An overrun error occurred during transfer. A character was not read from the hardware before the next character arrived.

I tested to read data from the VISA test panels in Measurement & Automation Explorer and repeat the same situation, also I can read for a pair of seconds and than receive the same error.

I'm working with the following settings:

Baud:57600

Data Bits:8

Parity:None

Stop Bits:1

Flow Control:None

Pleace, who have any idea?

Here I attach a foto of my program.

Thank for your time.

Hi Deutschrich,

are you sure that everything is correct within your hardware.

Your LabVIEW Code probably doesn't cause the problem, because otherwise the MAX should work correctly.

Maybe there is also something wrong with your VISA API, so you can also try to repair the VISA installation.

Let me know if this helped at all!

Hi TobyS,

Thank you for your reply,

I think there isn't problems with my hardware, because someone yet worked with it in Matlab and he didn't have problems. I think the problems is in the form how Labview receives data continually, because Matlab call a function every time when it want to read data.

I don't know where can be the problem really...I think I didn't have this problem when I worked with LV 8.5...

Perhaps the problem is in VISA or the program part of labview that manages the serial communication...

Hi Deutschrich,

did you try to reinstall or repair the VISA API installation?

Well I have not gone through the entire post but seems like the link given below will help.

Why Do I Get Buffer Overflows with My Serial Port When Using VISA with Flow Control?

Hi!

I can't solve my problem. I have probed installing again VISA and NI-Serial to a old version and I get the same problem.

I ran the MAX and Ï didn't find the "Advanced Settings". On Remote System I have nothing and on My System/Devices and Interfaces/Serial & Parallel, I find only Gereral and Port Settings but not Advanced Settings...

Can you help me pleace yet?

Thanks
