One thing to eliminate is your Windows machine:
Find your way to Device manager>Universal serial Bus Controllers>[some device]>Properties>Power Management tab, and make sure that "Allow the computer to turn this device off to save power" is NOT checked.
The other power-related issue is unpowered/under-powered USB hubs that cause devices to drop off. This may seem spontaneous, but it's more a case of power draws that may look fine initially, but if peak draws happen to coincide, poof!
Your firmware level is easy to check with the UFCT, and you should do that so you're sure. If you don't have a copy, there will be one in the zipped firmware and driver kit on the ES web site.
So, first thank you for bringing that to my attention. I've never considered how a windows device could affect it. I failed to mention that I am connecting using an iPad Pro over the hotspot wifi.
also, I should state that I also use this asiair pro on my ES EXOS2-GT mount with no issues and using the same connections. I have purchased another asiair (mini) and am going to dedicate it to this rig. I used the Pro last night because it was mounted to my telescope and I didn't want to change everything over in the dark for a test run. (it was easier to just move the scope and attachments... call me lazy I guess)
The mount and all the equipment are powered by a Jackery, the same one that runs this equipment on the EXOS 2-GT, so I am assuming that it should have plenty of power to run a smaller mount.
It has been so long since I have done anything with the firmware on my mount, that I have to admit I will have to research again how to check it using UFCT.
I tried to download the current software last night to my laptop, and ran into another issue. I could not get it to download to windows 10. Quick internet search let me know that there were problems with that, so I guess I have more reading to do on that topic as well. Unless someone knows why there is a reason for the firmware to not download to either of my compters? I guess I'm hoping someone knows. I've been pouring over the PMC-8 forums and although it's mentioned there, I haven't found a suitable answer as of yet.
Thanks for your responses and I'm sorry if this got a little long winded.
