View source for Template:FMB640 GPRS settings

GPRS defines main parameters for FMB640: GSM operator APN and GPRS username and password (optional – depending on operator), destination server IP and port, and allows to set protocol used for data transfers – TCP or UDP. SIM1 and SIM2 GPRS settings can be configured separate. Both server can be configured separately.
	FOTA WEB settings are used for FOTA WEB server connection parameters configuration. Status enables or disables FOTA WEB functionality. In domain and port fields user can enter address and port number of FOTA website. Period is used for timeout of repetitive connection to FOTA WEB server. 
''GPRS Settings'' define main parameters for {{{model|FMB640}}}: 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>. {{{txt_sim2|SIM1 and SIM2 ''GPRS Settings'' can be configured separately. }}}Backup server settings can also be selected for ''Backup'' 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>: records are sent 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>: records are sent to both servers (main and backup), records are deleted from SD-card (or RAMS) only if both servers accepted the records.
Some operators use specific type of authentication for GPRS session – CHAP or PAP. If any of these is used, APN should be entered as "chap:<APN>" or "pap:<APN>" respectively e.g. 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/>{{{model|FMB640}}} device will send the 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 set is the most recent one, as a result other records will be sent right after the newest records are received by AVL application.<br/>''Data Link Timeout'' is used to set termination timeout for link between {{{model|FMB640}}} and AVL application. If {{{model|FMB640}}} 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 {{{ctrSleepModes|[[Template:FMB Sleep modes#Deep Sleep mode]]}}}). 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.<br/>''Server Response Timeout'' is used to set a period of time waiting for the response from server side.<br/>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.
