Figure 25. Operator list configuration
If operator list is left empty, it will allow using GPRS to any GSM operator. Please note that
FM3620 will work in
Unknown mode only
(make sure it is configured to allow data sending –
GPRS context is enabled).

Data Acquisition Mode settings
Data Acquisition Modes are an essential part of FM3620 device, it is also highly
configurable.
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 5.12)
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 FM3620 to switch between Vehicle on Stop and Vehicle
Moving modes see section 0.
FM3620 allows having 6 different modes. Operational logic is shown in Figure 22.
