Value
Input
GPRS Access Point Name "APN"
These values vary according to the SIM card and VPN (Virtual
Private Network) in use. The values to be entered can normally
be obtained from your IT department or SIM card provider.
"Port" means the TCP port no. of the retrieval system in use.
APN Username "UName"
APN Password "PwAPN"
GPRS Port Address "Port"
i
If you fail to input an Access Point Name (APN), the APN that is saved on the SIM is used. Since
this is usually a public APN (no access to a VPN) and since a dynamic IP address is allocated
when a GPRS session with a public APN is set up, the TCP server function cannot be used! This
is because a static IP address would be needed for this purpose. In such a case, the modem
could only be used as TCP client.
Attention: Without the input of an APN there is the risk that unspecified costs may be incurred, as
with every set up through a GPRS provider and based on a corresponding tariff a minimum data
volume (e.g., 10 or 100 kB) will be billed!
Press the "

" icon at the top of the enSuite window.
If required (i.e. with the aid of the enSuite user list) two further addresses for a "Domain Name
System" can be entered in addresses 3:0794.0 and 3:0795.0. This is however not essential.
d) Setting time window for potential data retrievals
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.
i
Make the battery power time windows only as long and frequent as absolutely necessary. Each
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:
-
Parameters > Interfaces> Connections > Connection 1
and
-
Parameters > Interfaces> Connections > Connection 2
The two mains voltage time windows are set under:
-
Parameters > Interfaces> Connections > Connection 3
and
-
Parameters > 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.
