Hello,

Is anyone currently using LXI devices from a company called Bustec?

An absence of search results for "bustec python" is suggestive to me of a lack of openness.  That said, the code samples in linked manual look like any old VXI-11 device.  So it may just be that the commands obscured by this "helper" library.

If alternatives are practical, you might look into the TC-32.  Which is supported by the measComp epics module.

Any advice or pointers would be greatly appreciated!

As Mark mentioned, asyn+streamdevice seems like a reasonable approach for a device like this, where an IOC will likely just execute the same query command repeatedly.

With vxi11 devices, I usually start by exploring interactively from a python shell to learn about the inevitable quirks of these devices (there is always something odd...).

Also, wireshark has a vxi-11 protocol dissector.

Thanks,
