Media coupler as line coupler
The media coupler has a physical address in the form x.y.0 (x = TP area address, y =
TP line address / e.g. "1.1.0").
A KNX RF line can contain up to 256 devices (including media coupler)
(see figure 3). The media coupler is connected to the main TP line of an area. Addi-
tional TP lines can be set up using additional TP line couplers.
There may only ever be one media coupler in an RF line. Multiple repeaters
can be added to an RF line.
