4.6. Login the modem on the M2MTalk server
If you intend to use remote communication with the modem or data logger via GPRS (for
example to set up this device remotely), the modem always must be logged on the M2Mtalk server
before starting the communication. The modem can be set up to login on the server automatically
after its switching on, but it isn’t a standard factory setting.
To login the modem on the M2MTalk server, you can send a SMS message
login
to the
modem phone number. The modem will send back an acknowledge SMS message. It is advisable to
check the login status by sending SMS message
gsmstatus
to the modem phone number. If the
modem works correctly, it will send back SMS message with information. The login status is also
including in these information (M2MTalk online: yes).
Attention!
Since the modem is logged on, a limited data transferring also proceeds in
case the remote communication with the device isn’t in progress (due to keeping the
connection). Transferred data is charged as per your GPRS tariff by the mobile operator.
Around 26 kB of data per day are transferred for keeping connection purposes. If the full
up data logger memory is about to be downloaded, around 38 kB of data per day are
transfered for data loggers S/Rxxxx and around 1162 kB of data per day are transfered
for data loggers Gxxxx. Logout from the server is described in the chapter
4.7. Setting of the other parameters
The information that the alarm is active and information about correct operation of the data
logger can be periodically taken from the data logger by the modem. These informations are
processed and then the modem sends alarm SMS messages to a customer according to these
analyses.
The program for data loggers is used for setting of these parameters. If GPRS connection
isn‘t activated, you will have to set up the modem by using the setting cable.
There are these parameters:
data logger reading interval, see the chapter 6.1 on page 29
sending / no sending of the warning SMS messages, see the chapter 6.1 on page 29
phone numbers for the warning SMS messages recipients, see the chapter 6.1 on
page 29
phone numbers, from which the incoming SMS messages will be accepted by the
modem, see the chapter 6.1 on page 29
setting of the alarm conditions for the data logger if this functionality is required, see
the chapter 6.2 on page 35
