This has been driving me crazy. I am new to LabView and MAX. I could talk to the chamber last week and ran my LabView programs to control the chamber fine. However this week without changing anything, once I entered "*IDN?" in MAX and clicked "query", I got either *NA:COMMAND ERR", or "NA:N", or "NA" as response. This morning when I used the following commands on MAX, I got the weird responses as listed below.
Input: *OPT?; MAX response: NA:T
Input: *IST?; MAX response: NA:I
Input: *ESE?; MAX response: NA:E
Input: *ESR?; MAX Response: NA:R
I am using a GPIB-USB-HS cable, which works fine with other instruments.
What can be wrong with my setup?
Thank you very much!
