hp34970a WITH LABVIEW V5.0.1

I have a problem to use the VI's of hp34970A drivers. I couldn't communicate this VI's with this device by serial port. If I use directly the VISA easy serial, I can communicate with the device. What is happened? What do I do?

Hello IMMA �

Are you able to successfully perform the Hyperterminal test? If this works, verify that the serial settings on the VI are correct. Sometimes the LabVIEW standard setting might not be correct for your instrument.

If this suggestion does not solve your problem, please post an example program so I can recreate the problem. Have a great day!

Hi!
The Hyperterminal test has been successfully, then what's happened? I attach a file, if this help you to help me.
Thanks a lot to help me.

Note about file: the resource name is ASRL1::INSTR (I want to use COM1) and I use the 201 channel.

Hi IMMA �

Since your hardware is working properly, as proven by the successful Hyperterminal test, your problem is most likely related to LabVIEW or the HP34970a driver you are using. It appears that the current instrument driver for the HP34970a has a minimum compatibility requirement of LabVIEW 6.0 or 7.0. If it is important to your project to use direct serial communication rather than VISA easy serial, you may want to consider upgrading to a newer version of LabVIEW. 

Please let me know if I can be of further assistance. Thank
you for choosing National Instruments!

Thanks a lot for your help.
Finally, I decided to communicate with hp34970 by VISA easy serial.
