7.1.5
GPRS with ComTSC (Tainy Switching Center)
7.1.5.1 General details of the TSC system
If the TSC system is in use, the data is read from the terminal devices via a GPRS-TCP/IP connection. The
meter read out software "dials" a freely definable "call number" of a station. The
Tainy Switching Center
(the TSC-Server) has the task of setting up the connection between this (static) "call number and the
dynamic IP address (which changes from one GPRS session to the next) that has been notified to the GPRS
modem of the station to be called up during establishment of the current "GRPS session" by the GPRS
network and was subsequently reported automatically by the modem to the TSC server.
An essential precondition for such a connection via the GPRS network and the TSC system is the installation
in addition of a
virtual COM-Port-Client (CPC)
on the control center computer. The installation and the
operation of the TSC server and the CPC are explained in the TSC system documentation.
The parameters required for TSC operation must be configured separately in the EK280 modem (instead of
in the EK280).
Apart from the GPRS-TSC data transmission, the usual data call up through a GSM-CSD data connection is
also possible (although not simultaneously).
i
This application works only with a modem with "ComTSC" option. This option
must be requested when ordering the EK280. Compatibility is indicated by the
field marked "ComTSC" on the EK280 modem's label.
7.1.5.2 Parameterization of the EK280 for operation with an internal ComTSC-Modem
i
For parameterization of the EK280 you will require a connection cable for the optical interface as
well as the enSuite application, which can be downloaded for free at www.elster-instromet.com.
i
If your order for the EK280 stipulated "ComTSC", the EK280 has already been suitably
parameterized at the factory so that steps a) and b) in this section may be skipped.
Only if the modem application "ComTSC" is added locally later onto the modem (e.g. by the Elster
customer service) the EK280 parameters needs to be adapted by loading the corresponding wpp
file!
a) Closing the time windows
In order that the parameterization works correctly the time windows 1 to 4 must be closed. To do this proceed
as follows here.
Connect a PC or laptop with enSuite installed to the EK280 optical interface using the connection
cable.
Start enSuite and establish the communication link to theEK280 via the optical interface. (see
chapter 3.1 "Setting up the communication link to the EK280 via optical interface", page 15)
To do this 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 1 to 4 set start and end to the same val
ue 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):
EK280_xvx.. - int. ECM-GW-120
– ComTSC (*)
5
For the following customized settings and tests required, press
"Navigation"
on the left-hand side
and then
"Parameterize online"
at the bottom of the navigation window.

The "x" stands for the version of software on the device, e.g., "1v0".
The star * stands for a small letter which indicates the version of the file, e.g. "a".
