Which software or device is saying "not responding"?? Omnirig?? If you're not sure which, then is omnirig running when you get the message?? I recently tried switching to a DigiRig interface, and spent many frustrating hours trying to make the interfacing softwares work.?
For CIV control of the X5105, it responds to commands for Icom rigs like IC-7000, IC-7100, and some older Icoms.? Also, try setting the rig as Xiegu G90 and see if that works.
Unfortunately, I was so tired and frustrated when I finally got mine to work that I forgot to document all the settings.? I had been doing that in earlier stages of setup by taking screenshots and saving them to a file directory location I set up especially for them.
Taking - and saving - screenshots can help a lot with the setting up records.
