GPRS Modem -Dependent
Configurations
In addition to data calls and SMS messages, the GPRS modem can be
used to transfer data over the Internet.
Depending on the QML logger software version, GPRS
communications can be configured in two different ways. For software
version 6.00 and above, the TCP/IP functionality is provided directly by
the QML logger. For instructions, see
For software versions earlier than 6.00, the additional iConnector
module is required for TCP/IP connectivity. For instructions on GPRS
configuration with the iConnector module, see section
Configuration Using the iConnector Module on page 365
.
Application Alternatives
Autosend and/or Polled Operation
The autosend and poll functions can be freely mixed. For example, a
report that is automatically sent using e-mail transmission can also be
configured to be polled with a data call and issuing appropriate poll
command.
Another example of mixed use is an application where data is
periodically retrieved using data calls or polling, but urgent alarm
messages are sent immediately using SMS transmission.
To enable polling, enter the polling string as the Poll command
parameter and select Answer incoming calls in the Options dialog.
NOTE
The poll string sent by the remote system must always be terminated
with carriage return (<CR>, ASCII character 13). You do not need to
configure it to the Poll command parameter, as it is automatically
expected.
