Re: support for LXI devices (Bustec ProDAQ 6150 specifically)

Hi Richard,

I have used many VXI-11 devices.  VXI-11 is a subset of LXI.  I use StreamDevice to communicate, using SCPI (Standard Commands for Programmable Instruments) protocol.  The Bustec 6150 says it supports VXI-11.

I looked at the manual you referenced.  Unfortunately, they only discuss how to control it using the Web interface for configuration and Windows library they provide for acquisition.  I would guess that it probably uses the SCPI protocol for the actual low-level communication,  but this is not documented in that manual.  Without documentation for the SCPI commands you would be forced to use that Windows library.  Do you know if the SCPI commands are documented?

Subject: support for LXI devices (Bustec ProDAQ 6150 specifically)

 

Hello,

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

We are interested in using Bustec's ProDAQ 6150 (a 48-channel thermocouple measurement device) [1]. I checked the EPICS hardware support database and the Tech-Talk archives, but I couldn't find any mention of Bustec.

Since the ProDAQ 6150 is an LXI device, I know it can be interfaced with third-party software like EPICS. Before I attempt to develop support for it from scratch, I wanted to check here to see if anyone has already written something or has advice on the best approach (e.g., using asyn/StreamDevice) for Bustec specifically - or LXI devices in general.

For context, the device communication details are in section 6.3 (page 55) of the User Manual [1], which provides a few C code snippets demonstrating how to communicate with the device using their drivers.

Any advice or pointers would be greatly appreciated!

Thanks,
Rich
