just as a reminder here a very important change of the DMX output configuration in grandMA3 v1.1:
Out (default) - Constant 30 Hz DMX signal
Rdm - Drops down the refresh rate to 2.1 Hz when there are no changes on the respective DMX universe
The idea of the Rdm behaviour is to have more space for incoming RDM data. But there are devices which can not understand this DMX signal (even it is totally within the specs). Therefore we changed the default to Out with a constant 30 Hz refresh rate.
