Bitmain / Whatsminer are more plug and go. Avalon which I do like better and do find more reliable does tend to require a bit more setup knowledge.
Do you mean like the array connection of the miners using the AUC3 cables, AUC3 converters, and the controller? Or are there more to it?
That is mostly it. Thing is, some folks also have issues with setting up Ants and those are as simple as it comes... With the Avalon's the spot some folks have a problem with is either burning the SD card or dealing with the initial default static IP address. What I do is:
burn a micro SD card
change your PC LAN connection to use 192.168.0.101 or any address on the 192.168.0.xxx range
plug in the micro SD card and fire up the controller with it
on PC log into 192.168.0.100 and change pool and user settings to what you want
change from static to DHCP or set a different static address (I prefer DCHP)
Save and apply changes
Power off controller
remove SD card and plug back into card reader
read card and create an image file with the new setup
Then use that new file to burn cards for your other controllers
Now being DHCP look for the controller on your router and log in to check miner operation
Just refer to
Hagss setup guide for the A8's and you should have no problems.
