4 Wiring of EM260´s communication interface
If an analogue modem, an ISDN adapter or an Ethernet adapter is mounted inside the EM260,
the corresponding cable is also mounted by Elster-Instromet exworks. The cable is connected to
the terminals a(Rx-), b(Rx+), a2(Tx-) and b2(Tx+).
When using a CL0 interface, a shielded cable with two leads (e.g. ID no. 04250467, 2 x 1,0 mm
2
)
must be connected on site by the customer in the following way:
a (Rx-) CL- / Rx-
b (Rx+) CL+ / Rx+
5 Settings of the serial interface in the EK220/260/280
If the EK2x0 is delivered together with the EM260, the EK2x0´s internal serial interface as well as
the communication module integrated in the EM260 are properly set by Elster-Instromet exworks.
If the EM260 is delivered separately for additional installation beside an EK2x0, the internal serial
interface of the EK2x0 must be set in accordance with the software version of the EK2x0 and with
the type of communication module integrated in the EM260.
The serial interface of the EK2x0 must be parameterised before the EM260 is
connected to the EK2x0 and switched on.
For this purpose the parameter software “WinPADS200-EK“ or “enSuite” (only for EK280) can be
used:
- WinPADS200-EK: Menu “Data transfer”, item “Send parameter file…”
- enSuite: Item “Send parameter file”, then button “Open…”
Then you can select the parameter file (*.WPP) which fits to your application (communication
module, version of EK2x0).
Example:
EM260 with an analogue modem connected with an EK280 V2.0:
„EK280_2v2.. - EM260 & i-modul Analogmodem_a.WPP“
If there is no laptop with WinPADS or enSuite available on site, you can set the most important
values via the keypad of the EK2x0 (EK220/260: menu “Ser.IO”, EK280: menu “Terminal
Interface”).
The following values cannot be set via the keypad: SMS specific values, ISDN MSN, IP address
for Ethernet.
The following table contains the most important parameters which can be set via the interface
menu:
For the wiring, a shielded
8-wire cable
(Elster-Instromet ID no. 04250469) is
recommended. In the EM260 the cable
is assembled by Elster-Instromet
exworks. When connecting the EM260
to the EK2x0, please ensure the cable
is properly inserted into the EMV cable
fitting on the EK2x0.
