''GPRS'' defines main parameters for FMB120: GSM operator APN and GPRS ''Username'' and ''Password'' (optional – depending on operator), destination server IP and port, and allows setting the protocol used for data transfers – <span style=color:#F6A83E>TCP</span> or <span style=color:#F6A83E>UDP</span>. SIM1 and SIM2 ''GPRS Settings'' can be configured separately. Backup server settings can also be selected for <span style=color:#F6A83E>Backup</span> server .<br/>Backup server has 3 different modes:

* <span style=color:#F6A83E>Disable</span>: backup server is not used.
* <span style=color:#F6A83E>Backup</span>: send to backup server if main server not available (for example, Failed to open Link) or when main server response timeout is detected successively 5 times.
* <span style=color:#F6A83E>Backup</span>: sends to backup server if main server is not available (for example fails to open link) or when main server response timeout is reached successively 5 times.
* <span style=color:#F6A83E>Duplicate</span>: send records to both servers (main and backup), delete record from SD-card (or RAMS) only if both servers accepted records.

Some operators use specific authentication for GPRS session – CHAP or PAP. If any of these is used, APN should be entered as "chap:<APN>" or "pap:<APN>". I.e. if operator is using APN "internet" with CHAP authentication, it should be entered as "chap:internet". Information about APN and authentication type should be provided by your GSM operator.<br/>FMB120 device will send newest records first when <span style=color:#F6A83E>Newest</span> is selected in ''Records Settings'', which is useful in cases when the most important parameter to know is most recent position of the car, as a result other records will be sent right after newest records are received by AVL application.<br/>''Data Link Timeout'' is used to set termination timeout for link between FMB120 and AVL application. If FMB120 has already sent all records it waits for the new records before closing the link (except for Deep Sleep mode, for more information refer to [[FMB120 Sleep modes#Deep Sleep mode|Sleep modes]]). If new records are generated during the period of this timeout and minimum count to send is reached, the records are sent to AVL application. This option is useful when GSM operator charges for link activation.

FOTA WEB settings are used to configure FOTA WEB server connection parameters. Status enables or disables FOTA WEB functionality. Address and port number of FOTA website are entered to ''Domain'' and ''Port'' fields. ''Period'' is used to set the timeout of repeat connections to the FOTA WEB server.
