Apart from common errors such as loose contact, defect or no voltage the digitalSTROM transmission could be disturbed. digitalSTROM uses two different transmission methods:
- Transmission from the dSM to the components: downstream channel
- Transmission from the components back to the dSM: upstream channel
Then troubleshooting, the first step should be to determine which channel is affected/impaired.
For further information on downstream channel and upstream channel please refer to the installation manual.
