2.7 Send parameters
'Send Parameters' contains main information about data transfer. 'Send Period' defines time
interval for FM2 to check if it has enough coordinates (number defined by 'Min. Saved Records' in
'GSM Settings') and if so – open connection with server and send them.
Before data link with server is opened, FM2 checks if GPRS connection is available. If not,
then it checks if it can be opened: 'Send Week Time' table indicates when new GPRS connection can
be opened. FM2 algorithm allows to open new GPRS session if current time is less than 10 minutes
before nearest checked timestamp, therefore if all table is checked, FM2 is always allowed to open new
GPRS session.
FM2 is able to use GPRS transfers only if currently used operator is entered in 'Operators List'.
Usually home network code and roaming partner codes are entered in this list. If FM2 connects to an
operator that is not included in the list, it is not able to use GPRS no matter what 'Send Week Time'
table indicates.
'Time Step' field indicates a time interval between 24 coordinates sent as binary SMS. I.e. if
value is 3600000, then coordinates will be sent with every hour interval.
2.8 I/O elements
IO elements are additional data that can be sent with usual GPS data. These can be input or
output status, power supply voltage, odometer reading, etc. To add any additional property, it has to be
enabled.
