<span style=color:#F6A83E>Min Saved Records</span> defines minimum number of coordinates and I/O data that should be transferred with one connection to server. If {{{model|FM36YX}}} does not have enough coordinates to send to server, it will check again after time interval defined in <span style=color:#F6A83E>Sending Period</span>
<span style=color:#F6A83E>Min Saved Records</span> defines minimum number of coordinates and I/O data that should be transferred with one connection to server. If {{{model|FM36YX}}} does not have enough coordinates to send to server, it will check again after time interval defined in <span style=color:#F6A83E>Sending Period</span>
<span style=color:#F6A83E>Send period</span> – 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.
==GPRS Week Time configuration==
<span style=color:#F6A83E>GPRS Week Time tab</span> – most GSM billing systems charge number of bytes (kilobytes) transmitted per session. During the session, {{{model|FM36YX}}} makes connection and transmits data to a server. {{{model|FM36YX}}} tries to handle the session as much as possible; it never closes session by itself. Session can last for 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, {{{model|FM36YX}}} is able to open new connection anytime. At scheduled time match {{{model|FM36YX}}} checks for GPRS session activity. If GPRS session is alive, {{{model|FM36YX}}} sends data to server according to Send period parameter. If it is not, {{{model|FM36YX}}} checks if it is able to re-establish the session.

Device checks if the time between last saved record and current time is equal or higher than Time based acquire interval. If so, {{{model|FM36YX}}} saves record to memory. If not, {{{model|FM36YX}}} checks if the distance from last record to current record is equal or higher than Distance based acquire interval. If so, saves the record to memory. If not and speed is higher than 10km/h, then {{{model|FM36YX}}} checks if angle difference between last record and current record is equal or higher than Angle based acquire value. If so, saves the record to memory. These checks are performed every second.

FM3612 is able to collect records using four methods at the same time: time, distance, angle and speed based data acquisition:
Time based data acquiring (Min. period) – records are being acquired every time when defined interval of time passes. Entering zero disables data acquisition depending on time.
[[Image:FM36_interval_1.jpg|800px|none]]
Distance based data acquiring (Min. distance) – records are being acquired when the distance between previous coordinate and current position is greater than defined parameter value. Entering zero disables data acquisition depending on distance.
[[Image:FM36_interval_2.jpg|800px|none]]
Angle based data acquiring (Min. angle) – records are being acquired when angle difference between last recorded coordinate and current position is greater than defined value. Entering zero disables data acquisition depending on angle.
[[Image:FM36_interval_3.jpg|800px|none]]
Speed based data acquiring (Min. speed delta) – records are being acquired when speed difference between last recorded coordinate and current position is greater than defined value. Entering zero disables data acquisition depending on speed.
