Communication ISO-Tech IPS-3303

Hello together,

 

i know there a some similar topics. I read these threads already and many other stuff belong this topic. But the communication does not work anyway.

The Power Supply is connected over USB to the PC, there is a USB-Serial Converter inside the Power Supply i guess.

 

I can control and read values of the dievice with the VISA-Testpanel without any Problems.

If i took the same parameters and commands in LabView to the "simple serial communicaton.vi"-VI, nothing does work. .

When i tried to write, there is no error und no change on the device. If I try to read there is a Time Out Error.

 

I don't know how to find out what the problem is (i'm a LabView Beginner), can you help me to get this work?

 

Thanks a lot 

Greetings

Johannes
