Module login and password, server and authorised number list is used to protect
FM2200 module from unauthorised access. Module accepts messages only from a
list of authorised numbers and with proper module login and password. Numbers
must be without "+" or "00" prefix. If no authorised numbers are entered, module
accepts messages from all numbers. Server phone number automatically counts as
authorised number.

Send Parameter settings

Send parameters window allows to set GPRS and SMS data send periods, sending schedules, set
allowed operator list.
 Send period – GPRS data sending to server period. Module makes attempts to send collected
data to server every defined period. If it does not have enough records (depends on parameter
Min. Saved Records described above), it tries again after defined time interval
 Time step – FM2200 is improved with 24-coordinates-in-one-SMS sending mechanism. 24-
coordinates-in-one-SMS mechanism is used in areas where no GPRS coverage is available.
Module collects data and sends to server binary SMS containing information about last 24
collected points with interval between them defined in time step field. SMS sending schedule is
set in SMS Week Time tab. 24-Coordinates SMS decoding is described in "FM4100 FM2100
and FM2200 Protocols" document.
 GPRS Context Week Time tab – most GSM billing systems charge number of bytes (kilobytes)
transmitted per session. During the session, FM2200 makes connection and transmits data to a
server. FM2200 tries to handle session as much as possible. Session can last hours, days, weeks
or session can be closed after every connection in certain GSM networks – this depends on
GSM network provider. GPRS Context Week Time defines session re-establish schedule if
session was closed by network. New GPRS context is opened if time is 10 minutes till time
checked in table. Therefore if all boxes are checked, FM2200 is able to open new connection
anytime.
GPRS session is alive, FM2200 sends data to server according to Send period parameter. If it is
not, FM2200 checks if it is able to re-establish the session.
 SMS Week Time tab – week time allows setting SMS data sending schedule. SMS mode is
mostly used in areas where GPRS is not available.
Note FM2200 operates GMT time without daylight saving.
