15 Resistors to modify the C-Bus impedance:
Position
R180 / 183
R173 / 174 / 177 / 178
Impedance adaptation only required if C-Bus line is > 100m. For other impedance
values than 110 Ω or 50 Ω –> see document 1594.
16 Programming of "X1":
Use of E3H020
"CK" + supply from control unit (Input) (X1-17.. 20)
"CK" + autonomous supply (Output) (X1-17.. 20)

via header "ST2" (external modem) or via terminal block "X2" (internal mo-
dem).
Interface
RS232-1 internal modem via terminal block "X2"
external modem via header "ST2"
RS232-2 internal modem via terminal block "X2"
(Service port)
