Keithley 7512/7510 timeout Issues

[EricLoop]

Hello all,

I am trying to use the example code provided in the LV drivers for Keithley DMM. I connected to the DMM with USB and MAX identifies it. But it seems to have a timeout error when I try running the example code Keithley DMM7510 Acquire Signal.vi. 

The error seems to come from the IDN query however the IDN response from the DMM matches the string expression + SN and version. VISA Read happens when Query is turned off, occurs when the computer tries sending a *RST command to the DMM. 

Attached is the LV drivers for the Keithley DMM that I am using, below is a picture of the error out and MAX config

Have you tried testing the commands with the VISA Test Panel in NI MAX.

*IDN?\n and *RST\n commands.
Do you get the same outcome?

[EricLoop]

Yes, *IDN?\n query -

1: Write Operation (*IDN?\n)

Return Count: 6 bytes

2: Read Operation
Return Count: 52 bytes
KEITHLEY\sINSTRUMENTS,MODEL\sDMM7512,XXXXXXXX,1.7.12b\n

and *RST\n write comes back no errors-

1: Write Operation (*RST\n)

Return Count: 5 bytes

On my side runs ok, I'm using VISA 20.0
I was able to reproduce the error when selecting another port other than the one at the instrument

Ill take a look if I can find something else

That is odd. If it matters I am using a 7512, however that is just 2 separate 7510's. I tried using Ethernet connection instead of USB and produced the same error. When accessing through the Virtual Front panel via entering the ip in edge I can access the dmm just fine, however I do need to type in a login and password. Could this be the issue?

I continued digging and found the solution. I connected via ethernet and accessed the virtual manual panel for the 7512. I went into the configuration setting and changed the command style from TSP to SCPI and now it works. Looks like it saves that setting on power off as well.

Is good to hear that, glad you found it!
