Thanks for the quick replies...
Though your last comment seems confusing or maybe the way this whole RM is being sold is confusing and illegal... or at least in the EU.
So yea I do use over 256 channels, around 400... which is well within the full universe that I have paid for, and that anyone pays for when purchasing the RM.
Product description of the RM... "Out of the package, myDMX 3.0 software will run in Express Mode; 512 “Live” DMX channels & 512 “Stand Alone” DMX channels"
So one would assume that when this device is purchased can handle 512 channels of DMX straight away without having to do anything else... it really has to as that what's being sold...
Any tips how I can see if it is limited to 256 channels and where to unblock it?
