Instrument Control (GPIB, Serial, VISA, IVI)
Timeout error with ethernet instrument
Solved!
Hello,
I am having a hard time communicating with a Tektronix DMM4050 through Ethernet.
I added the device in MAX by adding by Manual Entry of Raw Socket (Auto-detect and manual entry of LAN instrument didn't work).
What works:
Provided I Enable Termination Character in I/O Settings, I can send the *IDN?\n query to the instrument, which results in a nice "TEKTRONIX,DMM4050,2199203,08/02/10-11:53\r\n" string.
What does not work:
The simple code below
Results in a VISA: (Hex 0xBFFF0015) Timeout expired before operation completed. error.
Any suggestion would be greatly appreciated 😉

What display format are you using for your string constant? Set it to "'\ ' Codes Display". Then you should have "*IDN?\n". I'm thinking if you switch the display it will read "*IDN?\\n" which will not terminate the command for the scope and therefore it does not recognize the command.
Hi crossrulz!
That was the problem. Thank you so much.
Alternatively, one can keep Normal Display and just insert a new line:
