GPRS Settings and Server Settings[edit source]

These settings define the main parameters for FMB920: 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 – TCP or UDP.


Second Server Settings[edit source]

Backup server has 4 different modes:

  • Disable: backup server is not used.
  • Backup: 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.
  • Duplicate: records are sent to both servers (main and backup), records are deleted from SD-card (or Flash storage) only if both servers accepted the records.

Some operators use a specific type of authentication for GPRS sessions – CHAP or PAP. If any of these is used, APN should be entered as "chap:<APN>" or "pap:<APN>" respectively e.g. if the 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.
FMB920 the device will send the newest records first when Newest 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.
Data Link Timeout is used to set termination timeout for the link between FMB920 and AVL application. If FMB920 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 Deep Sleep mode). If new records are generated during the period of this timeout and the minimum count to send is reached, the records are sent to the AVL application. This option is useful when GSM operator charges for link activation.
Server Response Timeout is used to set a period of time waiting for the response from the server-side.
