RE: [EXTERNAL] Re: support for LXI devices (Bustec ProDAQ 6150 specifically)

Quick Update – Bustec sent me a copy of a full SCPI programming manual they have for the ProDAQ 6150. I would provide the link here for completeness, but they said it has not yet been added to the public website, but the SCPI manual, combined with the insights provided here by Mark (Thanks, Mark!) tell me that the Bustec ProDAQ 6150 can be integrated into EPICS if needed/required.

 

Michael – Thank you for the insights on the Digilent TC-32 and the “out-of-the-box” EPICS support provided through the measComp module. If that unit meets our needs it will be a very attractive option.

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,
