Short burst data settings

FMM640 supports Iridium devices which can send short burst data (SBD) to server. This means that some data can be sent from FM device to server through satellites.

FMM640 will enable satellite mode only if device can not send data via GPRS. Satellite mode has his own Save/Send period. If timeout is set to 0 no periodic records will be made. It is not recommended to save records often because of satellites traffic price. 8 kilobytes monthly data limit is hardcoded in firmware. If data limit is reached – data limit counter will reset automatically only on next month first day or you can rest counter by SMS command “sbdlimitsreset”.

In addition, you can select which IO element can generate Satellite record. In order to do that you need to go to IO tab select IO record priority Panic and check checkbox “Satellite I/O” what you want to get that data through satellites if there is no GSM connection. Record which will be sent through Iridium satellites network will be different than the regular record. It will contain: 4 bytes timestamp, 3 bytes longitude, 3 bytes latitude, 1 byte record generation info, 1 byte DIN,DOUT info, 1 byte speed value.

NOTE: Port1/2 cable from FM package can be used for TSM232 connection. For this you need to cut a D-SUB connector and connect wires according instruction above (PIN 4 to TSM GND, PIN5 to TSM Rx, PIN6 to TSM Tx).

NOTE: SBD data is limited to 8000 Bytes per month. For firmware with bigger SBD data limit, please ask your sales manager. If data limit is reached you can reset it with SMS command “sbdlimitsreset”
