TCPIP VISA source couldn't be found

Anyone can help to look at this problem?

Hi,

Could you tell me what version of NI-VISA you are using, and what version of NI-488.2 you have installed? You can try downloading and installing the latest versions of the NI-VISA and NI-488.2 drivers.

When you say you hide the VISA Resource control, do you mean that that you made the control invisible, or that you had relocated it offscreen (by scrolling on the front panel)?

Let me know, thanks!

The VISA version is 4.1 and NI488.2 version is 2.5.

I just hide the visa resource control out of the screen.

I could try with latest version of VISA and NI488.2. Will let you know later of the results.

Thanks a lot!

I tried VISA version 4.4.1 and the problem is still present.

Hi lvfanqie,

Could you please try the following? Instead of using a VISA resource name control, to try using a string control instead.

The resource name should adhere to the following format: GPIBx::y::INSTR, where x is the GPIB Interface Number, and y is the Primary Address.

You should then be able to perform basic VISA write and read functions, as well as other functions such as the lock asynchronous and unlock.

Please try and see if that's something that will work for you.

After I replace the VISA control with string control, the problem is solved.

Although it is not the perfect solution, at least this hanging problem doesn't bother me anymore.

Thanks a lot!
