1 Safety Instructions
!Please read these instructions carefully before assembling, installing or commissioning
the EM260 to avoid any damage, dangers or problems.
Assembly and installation should be carried out by qualified personnel !
!The ‘AC’ version of the EM260 has a power supply of 90...260 V. Do not touch any live
parts as this is extremely dangerous !
Shut off the power supply before carrying out any installation work and before opening the
housing !
Switch the power back on only after all of the work has been completed and the housing
has been firmly closed!
Other notes:
)When using a GSM modem, switch off the power on the EM260 before inserting or
removing the SIM card!!!
)The PE connections in both the EM260 and the EK260 should be as short as possible
and have as wide a cross-section as possible.

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+). In the case of a GSM modem, a suitable GSM
antenna is connected directly to the GSM module.
When using a CL0 interface, a shielded cable with two leads (e.g. ID no. 04250467, 2 x 1,0 mm2)
must be connected on site by the customer in the following way:
EM260 terminal Terminal in the CL1 modem
a (Rx-) CL- / Rx-
b (Rx+) CL+ / Rx+
5 Settings of the internal serial interface in the EK260
If the EK260 is delivered together with the EM260, the EK260´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 EK260, the internal serial
interface of the EK260 must be set in accordance with the software version of the EK260 and
with the type of communication module integrated in the EM260.
)The serial interface of the EK260 must be parameterised before the EM260 is
connected to the EK260 and switched on.
For this purpose the parameter software “WinPADS200-EK“ can be used: Menu “Data transfer”,
item “Send parameter file…”. Then you can select the parameter file (*.WPP) which fits to your
application (communication module, version of EK260).
Example:
EM260/GSM with EK260 V2.51:
Æ„EK260_2v5.. - EM260 & int. GSM-Modem (Wavecom)_b.WPP“
If there is no laptop with WinPADS available on site, you can set the most important values via
the keypad of the EK260 (menu “Ser.IO”). The following values cannot be set via the keypad:
SMS and GSM specific values, ISDN MSN, IP address, modem parameters.
The following table contains the most important parameters which can be set via menu “Ser.IO”:
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 EK260, please ensure the cable
is properly inserted into the EMV cable
fitting on the EK260.

3) This setting (number of rings) is not used in mode 5. In mode 5 the communication module in the EM260
always picks up an incoming call after the first ring signal.
4) Numbers in bold: Exworks settings performed by Elster-Instromet if the EK260 is delivered without any
modem.
6 Setting the parameters for the communication module
The parameters for the communication module (modem) in the EM260 are set ex-works for use
with an EK260.
If the parameters have to be modified on site, this can be carried out with the help of the
parameter software “WinPADS200-EK“: Menu „File transfer…“, item “Send parameter file…”.
Then you can select the parameter file (*.WPP) which fits to your application (communication
module, version of EK260).
Example: EM260/Analogue modem with EK260 V2.51
Æ“EK260_2v5.. - EM260 & int. Analog-Modem (Insys)_a.WPP“
Before disconnecting, the button “Init modem“ should be pressed (“Interface – Modem
initialisation“). Æafter it is disconnected, the EK260 sends the parameters to the communication
module. The parameters are also sent after switching on the power supply and after “M.INI=1” in
EK260´s menu “Ser.IO”.
The parameterisation of the communication module does not work with all EK260 versions and
also not with all types of communication modules. The following table shows the dependences
(“x“ means: Communication module can be parameterised by the EK260):
Communication module in EM260Software version of
EK260 Analogue GSM ISDN Ethernet CL0 Remarks

2)
1) Parameterisation can be carried out only by Elster-Instromet exworks or by Elster-Instromet customer
service on site with the help of the software tool “ModemIni“ (ID no. 73017249). In the case of a
Wavecom adapter board V1.1 (GSM modem), the modem programming adapter (ID no. 73018295) is
also required.
2) CL0 interface need not be parameterised
3) The modem parameters, of course, can be set by “WinPADS200-EK“ („Interface – String for connected
modem“), but after carrying out the parameterisation (Button „Init modem“, „M.INI=1“ or switching on
power supply) they must be deleted again!!! Otherwise the communication module will not pick up any
further incoming call!!!

7 Replacement of communication modules
A faulty communication module can be substituted by another communication module of the
same type by the customer on site. It depends on the software version of the EK260 and on the
type of the communication module if the new module can be parameterised on site or if it must be
parameterised by Elster-Instromet exworks (refer to the table in chapter 6).
The replacement of a communication module by another communication module of a different
type (e.g. analogue modem replaced by ISDN adapter) can only be carried out by Elster-
Instromet exworks or by Elster-Instromet´s customer service.
8 Power supply
The voltage required for power supply is marked on the nameplate (90...260 VAC / 18...30 VDC).

11 Modem Reset
11.1 Modem-Watchdog
In EM260/GSM with Wavecom-Adapterboard
starting from V1.2, a Watchdog function is
implemented ex-works. The watchdog controls
the modem function and resets the modem in the
case of a failure.
The watchdog is active if the jumper ”JP7“
(“Watchdog“) is in the position “enabled“.
11.2 Cyclical modem reset via output 4 of the EK260
After activating the modem reset function the modem is restarted once a day via output 4 of the
volume corrector. Time and duration of the modem reset are defined by the time window 2 of the
EK260. If time window 2 is used to control the modem reset, it can no longer be used as a call
acceptance window. In this case, call acceptance is exclusively defined by time window 1.
)In EM260 with Wavecom adapter board starting from V1.2, a watchdog function (refer
to chapter 11.1) is implemented ex-works. The watchdog controls the modem function
and resets it in the case of a failure.
The presence of the watchdog makes the cyclical modem reset via output 4 of the EK260
unnecessary. Output 4 of the EK260 can still be used for call acceptance.
)The modem reset function should be activated only if necessary (if manually operated
modem resets have repeatedly been necessary to ensure the accessibility of the
modem)!
Ex-works the modem reset function is not activated!
To activate the modem reset function, it is necessary to send a special parameter file to the
EK260 and to modify the wiring between the EM260 and the EK260 (see below).
Before activating the modem reset function, the following conditions must be fulfilled:
The version number of the Wavecom-Integra-Adapter board (ID no. 73018344) inside the
EM260 must be 1.1 or higher.
On a Wavecom-Integra-Adapterboard V1.1 the soldering pad LF7 must be short-circuited,
e.g. by a 0 Ohm resistor.
In the case of an EK260 V2.2x, the modem reset function cannot be activated when a SIM
card with an active PIN is in use.
Jumper „JP7“ (Watchdog)

Manual EM260
with Volume Corrector EK260
Betriebsanleitung-EM260-EK260_en_f.doc 7 of 8
If, in the case of an EK260 V2.4x, the modem reset function should be used together with an
active PIN, the time windows in the EK260 must be set in the following way:
a) Time window 1 (call acceptance) must be open at 00:00 o´ clock
b) Time window 2 (modem reset) must be open shortly before 00:00 o´ clock
Reason: The EK260 V2.40 sends the PIN query command (AT+CPIN?) only at 00:00
o´clock and only if time window 1 is already open at 00:00 o´ clock !!!
Example of setting for the time windows:
Time window 1 (call acceptance): 23:59 to 23:55 o´ clock
Time window 2 (modem reset): 23:55 to 23:56 o´ clock
Parameter file for cyclical modem reset
If a cyclical modem reset is to be carried out and if all conditions for its use are fulfilled (see
above), a special parameter file has to be loaded into the EK260. The name of the parameter file
to be used depends on the software version of the EK260:
“EK260_yvy.. - Funktion=Modem-Reset täglich EM260_x.WPP“
(where yvy = software version of the EK260, e.g. 2v5 and x = latest file index)
)For a cyclical modem reset, output 4 of the EK260 must be connected to the modem
reset input! (ÆWiring instructions see below)
Wiring instructions for cyclical modem reset
If a cyclical modem reset is to be carried out and if all conditions for its use are fulfilled (see
above), the wiring between the EM260 and the EK260 must be modified as follows:
EK260 clamp Signal direction EM260 clamp
Uext + Å+9V
Uext - not connected GND
Wavecom-Adapter-Board V1.1 or higher
+9V
DA4+ ÆSwitch
DA4 - not connected
)If output 4 of the EK260 is connected to the modem reset input, it is absolutely necessary
to load the corresponding parameter file into the EK260 !!! (Æsee above)
