#31 communication with same instruments times out

[Robert]

Hi,

I installed linux gpib on Ubuntu 21.04 and installed and configured pyvisa etc.

ibtest is working and I can also use pyvisa and/or gpib. I have currently three devices hooked up.

2460 Source meter is working flawlessly: write and read and query works well.
I am having trouble with 2420 Source meter and SR844 Lockin. I can write and configure the instruments but the read and query time out. I have no idea why this is :/

Any suggestions how to resolve this issue?

ibtest for 2420:

trying to read 1024 bytes from device...
received string: 'KEITHLEY INSTRUMENTS INC.,MODEL 24'

Hi Robert,
Do the 2420 Source meter and SR844 Lockin assert EOI at the end of
their message ?

Hi,

I am not sure about that. How can I check/change that?

In python I tried numerous terminations for read and write comments without success.

Cheers,
Robert

Would you try svn revision 1985? I found a possible cause of your issue.

[Robert]

That sounds promising. Please tell me what to do and how to do it.

Robert

Well, you could just edit the code you have with the 2 line changes shown here:

https://sourceforge.net/p/linux-gpib/code/1985/

Or you could checkout the svn trunk. Then rebuild/reinstall/reload
the linux-gpib-kernel modules.

[Robert]

I changed the code. Cleaned and remade installed it (kernel only). Nothing changed :/

Robert

Did you rmmod the old modules, or reboot? If it is something else,
you'll probably have to debug tnt4882_accel_read() in tnt4882_read.c
yourself and figure out why/where it is getting stuck to make
progress.

I rebooted to be sure.

Writing is going well and fast just the response is not. Dang.

Hi,

I installed linux gpib on Ubuntu 21.04 and installed and configured pyvisa etc.

ibtest is working and I can also use pyvisa and/or gpib. I have currently three devices hooked up.

2460 Source meter is working flawlessly: write and read and query works well.
I am having trouble with 2420 Source meter and SR844 Lockin. I can write and configure the instruments but the read and query time out. I have no idea why this is :/

Any suggestions how to resolve this issue?

Hi Robert,
Have you tried setting set-reos = yes in gpib.conf for the 2420 ?
From the 2400 manual: "Response message terminator (RMT) Each response
is terminated with an LF (line feed) and EOI (end or identify)."

I rebooted to be sure.

Writing is going well and fast just the response is not. Dang.

Cheers,
Robert

Did you rmmod the old modules, or reboot? If it is something else,
you'll probably have to debug tnt4882_accel_read() in tnt4882_read.c
yourself and figure out why/where it is getting stuck to make
progress.

I changed the code. Cleaned and remade installed it (kernel only). Nothing changed :/

Well, you could just edit the code you have with the 2 line changes shown here:

https://sourceforge.net/p/linux-gpib/code/1985/

Or you could checkout the svn trunk. Then rebuild/reinstall/reload
the linux-gpib-kernel modules.
