9 Double flat cable header "ST1" (26-pin):I-Bus from E3C011 (if used)
10 3-pin female connector with 2-pin jumper
11 4-pin female connector
12 Plug-in terminals "K1": Supply line from E3C011 (if used)
13 Plug-in terminals "K2"
14 Lithium battery 3 V / 70 mAh: RAM buffering and clock supply
– Data safeguarded: minimum 2 weeks, typical >100 days
– maintenance free
15 Resistors to modify the C-Bus impedance:
Position
Impedance value 110Ω,
e.g. for G51 0.6mm Ø
Impedance value 50Ω,
e.g. for MICC
R180 / 183
402 Ω 182 Ω
R173 / 174 / 177 / 178
110 Ω 49.9 Ω
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
0 Ω-resistors
”CK” + supply from control unit (Input) (X1-17.. 20) X15 + X16 + X17 + X18
”CK” + autonomous supply (Output) (X1-17.. 20) Y15 + Y16 + Y17 + Y18
17 Programming switch "S5": Interfaces RS232-1 and RS232-2, choice of path
via header "ST2" (external modem) or via terminal block "X2" (internal mo-
dem).
Programming switch S5 Interface Application
1 2
internal modem via terminal block ”X2” off – RS232-1
external modem via header ”ST2”
on –
internal modem via terminal block ”X2” – off RS232-2
(Service port)
external modem via header ”ST2” –
on
Set to ”off” at factory
