Commands that work in MAX do not work in Labview

[Bruno Borba]

I am developing a driver for an instrument using a TCP/IP protocol. I test the commands that are in the instrument's manual in MAX and they work perfectly, using VISA functions. However, when I try to do this in Labview, using the same VISA functions used by MAX, it does not communicate with the instrument.

Hello,

Thanks for contacting National Instruments.

There a few things that might be causing the problem you are seeing. One possibility is that your program in LabVIEW does not use the correct termination. Another possibility is described in the following Knowledgebase.

Also, if you have LabVIEW 7.0, I would also suggest trying to use the Instrument I/O Assistant to communicate with your instrument. This simplifies the communication and can hopefully help you to communicate with your instrument.

Hope this helps!
