I am trying to work out the best solution to use the UE9pro directly over ethernet on linux in a custom application via an API. There seems to be everything else but what I need. I haven't downloaded anything yet so maybe there are answers in the source documentation.
The UD looks like the API I want however it is windows only.
The UE9 instructions point to the Exodriver however it looks like it is usb only.
There is this alpha LJM Driver which might do the trick but there is no documentation on what it really is that I can find.
LJFuse. It isn't clear on the webpage if this is for ethernet connection (although a comment says no), or addresses issues like response time through the layers.
LJSocket absracts a USB UE9.
So ... it seems the best technique is custom code to reimplement the UD API on top of linux modbus. Perhaps start with the UD source release and recode to talk to the linux modbus driver?

UE9 + ethernet + linux

I believe the Exodriver does support Ethernet, but am marking this for someone else here to comment on that.
LJM is nice, but definitely alpha and we are only testing on the new T7 device at the moment. Worth considering, but my suggestion would be that rather than use any driver at all you just do direct Modbus (which will require that you upgrade to UE9 Comm firmware V1.43):

What programming language are you using?

The Exodriver is USB only, though it still provides helpful example code on setting up low-level functions. Here are some cross-platform, low-level function TCP examples written in C which doesn't require a driver:

If you don't mind using Python, we provide a high-level interface (LabJackPython) that supports both USB and ethernet:

LJFuse is USB only.

Programming lanugage C/C++
The c-native-tcp-example should be appropriate for my purposes.
Thanks.
