Question about Devolo dLAN 1200+

The dLan pro 1200 DINrail is from the same manufacturer and not "unrelated".
The question is whether the "pro" line is compatible with the consumer line. I would like to use the pro line for the connection to the cable modem because the DIN version has a 3-phase connection and can thus communicate safely on all 3 phases with the plug adapters over longer distances.

Daniel, these are powerline devices, not modems! You can only use them to enable a fast LAN connection via the existing power cables.

If you plan to do this and if you connect these ingenious devices to other devices (powerline adapters of other types), you will at least lose transmission speed and may not be able to establish a usable connection.
Forget it.
