Hi I'm trying to use LabVIEW to control a R301 RF generator (both sending request and getting RF status) and failed to do that. This is the message continuously jumping out whenever I try to run LabVIEW. I used the serial connection of RS232 between the computer and RF generator and I'm 90% sure the connection works. I checked and found a lot of people having this problem but unsolved. Is gonna be really helpful if anyone can help. Thank you!
Attached is our LabVIEW program.

90% sure?
That isn't good enough.
Use NI-MAX and make certain it is 100% before trying anything with LabVIEW.

I successfully detected it in MAX. I think it's buffer problem but DON'T know how to solve it

No, you need to use NI-MAX NI-VISA's VISA Interactive Control or any program such as Hyperterminal to interact with the device

Hi,
I have problem with the same error "VISA: (Hex 0xBFFF00A6) The connection for the given session has been lost."
I try to connect to digital multimeter via serial comm and i want to read measurements from labview. I did all driver needs and manage to read data from read buffer first day. but now i always get this error messages and sometimes "connection has been lost". I handled with connection lost but not I/O problem.
Write part is labeled OK. REad part gives the I/O error
And second question is first day i can only read "one" data from multimeter then ı run the labview again. Multimeter produces data continuously and i want to read data unless i stop.

I'm beginner Labview. i began last week to learn about labview. That's why i couldn't mention something true.
i download MAX and NI-Serial and i add attachments from MAX and troubleshooting may be it helps whats wrong
-How can i disable energy conversation for comm. that you mentioned
1)i setup usb driver for my digital multimeter GW instek 8255a.
2)Create inf file
3)Create instrument driver in labview library
these are which i can remember for setup. Is there any missing step for creating setup?
-Pls can you tell me step by step for configuring serial communication for multimeter.

i apply steps for inf file from NI USB Instrument Control Tutorial
in that link, http://www.ni.com/tutorial/4478/en/
( i donot want to write steps briefly because of my insufficient english.)
i supposed gw instek-usb driver initialize the function (but now in their site i couldn't find their driver. They remove driver.) Anyway driver didn't change anything about communication or i did something wrong.
