serial communication timeout

[Sriram_Iyer]

Hi all,  

I can able to communicate with my hardware via serial VISA and also i can read the data relative to my hardware operation. 

Here where i am having a problem:

Since my hardware continously sending data, if the specified timeout in VISA Serial Port Configure is not sufficient, it is giving a timeout error and application was stopped. I can able to continue my read operation on my next run. 

But i want to read data continously until i abort this operation.

Please guide me on this.  Awaiting for reply.

Thanks and regards,

Sriram

It would be better if you attach code here. My guess is, you did not have any delay time between write operation and read operation. See this link

Thanks for your reply.

In my case I am not writing anything to the hardware, instead i am just reading the data.  So i think write operation is not at all required here.

Also i have you that VI.

Drag out the "VISA serial" intialization VI out of the loop and put only READ visa inside the loop.

Calling serial VISA init outside the loop is solving my issue. VI was exactly stopped at the specified timeout.
