Hi, i want to know the same thing..
from my knowledge when the current version of pimax software is installed , it has nolo drivers in built to pimax software and will auto detect and load it so user does not have to load nolo drivers or software separately.
All is fine, only the catch is that CEILING mount is no longer supported. And if you try to replace the 180 degree DLL file with the 360 DLL file, it doesnt work. This was how it was done in the old version of pimax software.
For some reason when the new pimax software of developed they did allow for this feature, which i think is quite important as users who by Pimax4K HMD will next step buy the Nolo controllers also.
And given Nolo is standard front mount, users will eventually want to advance to ceiling mount to get full 360deg tracking vs. 180deg only, given that the new software for nolo allows for ceiling mount... but this feature is not made available when Nolo was integrated into pimax software.
a fix to the pimax software to allow user to select ceiling mount function would be awesome
