10.4 Technical data DALI

Transmission medium (bus cable)
Baud rate
Bus line polarity
Bus terminating resistor
The communication signal (information) is transferred symmetrically, i.e., as
voltage difference between the two bus lines (and not as a voltage difference to the
earthing potential). The sign preceding the voltage between DA+ and DA–
determines signal values 0 and 1.
