Couplers - KNX Advance Course - Chapter01

[@andelibparody]

I dont get the concept of repeater and line coupler. If I locate my coupler in 1.2.0 as a Repeater does it still execute under 20 devices ? for example: 1.2.0 as a repeater up to 1.2.21. Does it work? or it has to be line coupler?

1.2.0 is line coupler and not repeater. when u order they are same but in configuration the physical address and database are different.

Is it true that the individual address 1.0.135 does not exist?

For the devices before 2018 , we can not extend the main line, so we can include 64 devices minus the LC. For the devices after that if they support new topology we can have 256 DVC minus LC.
