By configuration user defines how records will be saved and sent. There are three different
modes: Home, Roaming and Unknown. All these modes with configured data acquisition and
send frequencies depend on current GSM Operator defined in Operator list (see section 5.6) and
are switched when GSM operator changes (e.g. vehicle passes through country boarder).
If current GSM operator is defined as Home Operator, device will work in Home Data
Acquisition mode, if current operator is defined as Roaming Operator, device will work in
Roaming Data Acquisition mode, and if current operator code is not written in Operator list (but
there is at least one operator code in the operator list), device will work in Unknown Acquisition
mode.
This functionality allows having different AVL records acquire and send parameters values
when object is moving or stands still. Vehicle moving or stop state is defined by Stop Detection
Source parameter. There are 3 ways for FMB900 to switch between Vehicle on Stop and Vehicle
Moving modes see section 5.7.
FMB900 has 6 different modes. Operational logic is shown in Figure 24.
If there are no operator codes entered into operator list, FMB900 will work in
Unknown network mode ONLY.
