EK280 Application Manual 69
7.2.2
EM260 with analog modem (PSTN modem)
Prerequisites for process described below:

The EM260 is connected and disconnected to EK280 and switched off (without power in accordance
with Chapter 7.2.1 .
7.2.2.1 Parameterization of EK280 for operation with an EM260/analog modem
I
For parameterization of the EK280 for use with an EM260/analog modem a connection cable is
required for the optical interface as well as the enSuite program, which can be downloaded free of
charge from www.elster-instromet.com if required.
a) Closing the time windows
In order that the parameterization works correctly the time windows 5 and 6 must be closed. To do this:

Connect a PC with enSuite installed to the EK280 optical interface using the connection cable.

Start enSuite and set up the communication link to the EK280. (see chapter 3.1 "Setting up the
communication link to the EK280 via optical interface", page 15)

Select " Navigation " on the left-hand side and then " Parameterize online " at the bottom of the
navigation window.

In the top of the device window open the path " Parameters " > " Interfaces " by clicking on the relevant
plus signs, and then select " Call time windows ".

In call windows 5 and 6 set start and end to the same value for each one and then select the
“
Transfer changes to device " icon at the top of the enSuite window.

Then wait a minute, for any communications activity in progress on the EK280 to be safely stopped.
b) Send parameter file

Send the following parameter file to the EK280 (see Chapter 3.6, "Send parameter file", page 17).

i
By loading this parameter file, the transmission speed at the terminal interface of the EK280 is
reduced to 9600 bps, even though EK280 can normally communicate across this interface at
19200 bps. This is necessary, because during operation with EM260 versions of model year up to
2009 inclusive, transmission speeds of up to 19200 bps may lead to problems!

For any further individual settings and tests required, press " Navigation " on the left-hand side and
then " Parameterize online " at the bottom of the navigation window.
i
All the values listed in enSuite under "Parameter" can be found on the "Serv." display tab of the
EK280 under the same path.
c) Setting time window for potential data retrievals
i
Before the first opening of a time window, the Em260 must be connected to the EK280 (

see
Section 7.2.1) and the parameters be set (

see Section 7.2.2.2)!
In the base configuration now displayed you can define time windows, during which data can be cyclically
retrieved from the EK280 via the modem. Time windows 5 and 6 are reserved for EK280 operation with an
EM260. Redundant time windows can be deactivated by setting the time window start and end to the same
value.

In the top of the device window open the path " Parameters " > " Interfaces " by clicking on the relevant
plus signs, and then select " Call time windows ".

For call window 5, set the start to "00:00" and the end to "23:59" and then select the "Transfer
changes to device" icon at the top of the enSuite window.
6 The "x" stands for the version of software on the device, e.g. "2v2".
The * asterisk represents the lower-case letter, used to identify the file version, i.e. "a"
