The digitalSTROM protocol has been designed from the beginning to work efficiently even with a small baud rate. The communication of events and mood scenes actually needs very small baud rates. In addition, every circuit is an independent communication circuit thus each dSM multiplies the system baud rate of an installation. The downstream channel (communication from dSM to the terminal blocks) has a transmission rate of 100 baud/s; the upstream channel (communication from terminal blocks back to the dSM ) has a transmission rate of 400 baud/s.
