Prologix gpib to usb converter python code

My previously misspent youth was taken up with doing very serious O. What's new with the as opposed to that is that it includes a 2-chennal, 50MHz DSO as part of the package. Real cute, albeit primitive by current standards. That is a serious disconnect between cost of materials and sales price. Even the One Hung Low stuff is about that price. There is one notable exception, and that is a little honey from Softmark, in Australia not Austria.

I don't know if you or any of the other crazy Aussie blokes down there have any experience with such gadgets, but I would be interested in knowing why the Softmark converter is so cheap compared with all the others, and whether it is truly usable with LabView or any such stuff on my PC. Thanks muchly, J. Klaatu Barada Nikto! Stoner Bifrost Development Group asgard jeffnet. The Softmark converter is pretty useless. I would not touch it. It is extremely limited in GPIB capability, and I think it only works via the provided very lame software.

Isn't it run from a parallel printer port? If so, who has a parallel printer port? The good news is that things are not quite as bad as you think. These options are fully compatible with most recent IEEE Steve scasagrande did a great open source board that he was selling, but you could get all the info to make your own.

Connect and share knowledge within a single location that is structured and easy to search. Im using windows 7 and python 2. And I need to program using python. I just need to send simple command for example R to run the machine. How can I send any command to the machine? From what I know, I need to send it to the driver of the NI Is it correct? How to see the code of any driver? But in my case the driver for NI For the registration, basically you just need to leave a email address of yours.

The proposal is to create a custom Resource that handles deals with the prologix device without requiring extra commands from the user. The text was updated successfully, but these errors were encountered:.

With the NI backend, you get a serial port and no way to tell it's an adapter I checked all the attributes with pyvisa shell. So the user would have to tell the library about this.

Sorry, something went wrong. For example, talking to a devices in serial port 1 via a prologix adapater that simulates a device in GPIB 2 is:. This is really easy to parse and dispatch. It might also remove the question of the underlying resource. Feel free to repost it if you feel like doing it. Here is what we implemented.

It helps a lot. Because then any program or library that uses PyVISA will profit automatically just using the right resource name. The code stadi posted is a very useful starting point.

One immediate limitation is the lack of support for multiple instruments downstream from a single Prologix adapter. Has anyone made progress on this front? On Fri, May 29, at PM, roamingryan notifications github. Actually I never used this adapter with more than one instrument. We also have the expensive NI adapters for that purpose. We control all new instruments over LAN and LXI which is much cheaper : However I think to control multiple instruments, it is necessary to instantiate the serial.

Serial object in a higher level s. Another possibility could be to provide the Serial object to the wrapper as an optional parameter. Otherwise the already created serial object is forwarded to the Prologix instrument class. Maybe I can provide the some code next week. Feel free to try it yourself :. I checked the code and actually it would support multiple instruments but there is an indentation bug. The serial. Serial object is now created globally and reused, if another instrument is instantiated.

Here is the corrected and verified code:. If I am using a prologix usb-gpib adapter, how do I then access the devices on the gpib bus? The user needs to be in the dialout group to access the VCP. Finally, you may have to modify the version check so it doesn't throw an exception.
