3. Parameterize the time at which this FTP task is to be executed, as well as the server on which these data
are to be stored ("Connection").
These steps are described in separate instructions  FTP Application manual [10].

From the EK280-V2.50, a modem used for FTP data transmission can be used for FTP and CSD
connections  chapter 7.1.4) as well as for TCP connections  chapter 7.1.5). However, there
should only be one connection at a time.
7.1.6.3 FTP data transfer via GPRS with ComFTP (EK280 up to V2.40)
For an active ComFTP application, data is read from the EK280 by the modem and transferred
independently using the PUSH principle from the ComFTP modem to a FTP server set up beforehand. This
function must be commissioned separately in the modem itself ( "Operating instructions modem application
ComFTP", ID no. 73019546).
In addition to the FTP function, the standard GSM/CSD mode (PULL principle) is also possible by calling a
data telephone number (albeit not at the same time).
i
The active ComFTP application will incur costs due to continuous data volume transmission via
a mobile network. Estimate adequate reserve for this. Talk to your provider to obtain an
economical tariff. Switching off roaming can also help to reduce costs. Optimization of these
factors is your responsibility.
i
Wireless networks can be disrupted, therefore one hundred percent data transfer cannot be
guaranteed in any case.
i
This application works only with a modem with "ComFTP" option. This option
must be requested at the time of ordering of the EK280. Compatibility is indi-
cated by the field marked "ComFTP" on the EK280 modem's label.
i
It is essential that you carry out the activities in the exact order described to obtain the desired
result.
7.1.6.3.1 Prerequisites for operation with ComFTP
The following conditions must be fulfilled to enable operation of the ComFTP application:
− The ComFTP server must be configured. It is vital to ensure that adequate free space is available.
The directories used for standard response and archive transfer must exist.
− ComFTP server maintenance must be assured - the data must be processed in a timely manner. If
this is overlooked, data loss may occur. Talk to your IT department or relevant service provider about
this.
