The LMS-D6 is a de-specced OEM variant of the XTA DP226. Part of the OEM process included dropping the AES/EBU digital input and the serial interface for use with Audiocore to name a few key matters. The RS-232 Port is for uploading presets etc. So in short no you can't use Audiocore with a LMS-D6.
Turbodrive operates, monitors and controls our current controllers LMS-D24 & D26, as well as any self powered NuQ DP or TA-500DP products.
