d) Setting time window for potential data queries
In the base configuration now displayed you can define time windows, during which data can be retrieved
cyclically from the EK280 via the modem. There are two available time windows, which operate on EK280
battery power only and for versions of the EK280 with power supply there are two more, which operate only
on mains voltage.
Make the battery power time windows only as long and frequent as absolutely necessary. Each
i
time window reduces the EK280's battery life.
The editable time windows are not directly accounted for in calculation of expected battery life of
the "Bat.R" EK280 batteries. Therefore the expected battery life is not updated, when the time
windows are changed. Past time windows and data transfers are however used in remaining
battery and service life calculation for the "BatRC" .
The two battery-power time windows are set in the enSuite device window under:
- Parameter > Interfaces > Connections > Connection 1
- Parameter > Interfaces > Connections > Connection 2
The two mains voltage time windows are set under:
- Parameter > Interfaces > Connections > Connection 3
- Parameter > Interfaces > Connections > Connection 4
If you do not need a time window, you can deactivate it by setting the time window start and end to the same
value.

6.1.3.2 Checking GSM field strength
Before starting a data transfer via the modem, you must ensure that there is adequate reception field
strength.
Move the cursor to the "Serv." tab in the EK280's display, then to
Interfaces > internal modem > GSM and GPRS > GSM.L
With the cursor over GSM.L, please press the EK280
seconds.
The percentage field strength is now displayed under GSM.L.

With a field strength below 50% data transfer issues may be encountered. You can remedy this
in the majority of cases with an external antenna, mounted somewhere suitable.
