Data Acquisition Mode Settings - Teltonika FMB920 User Manual

operator, not roaming. Any not written operator in roaming operator list (not home operator)
will be recognized as unknown operator and FMB920 will work in Unknown mode (make sure it
is configured to allow data sending – GPRS context is enabled).
Operator Blacklist - if user wants that FMB920 do not connect and work with a particular
operator it must be written to Operator BlackList. Total 50 operators can be written to this list.
Operator Blacklist working: Operator search procedure is initiated as normal every 15
minutes. If device connects to operator from black list – best operator search procedure is
initiated instantly. Depending on White list device finds new operator to connect to. If no
operator was found in configured White list – device tries to connect to operator with strongest
signal, except if it's in Black list, then second best operator connection would be initiated and so
on. During the time when device is connected to Black list operator - no GPRS connection would
be initiated and no data would be send via GPRS.

Data Acquisition Mode settings

Data Acquisition Modes are an essential part of FMB920 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 Roaming Operator list (see section
5.8) 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 Roaming 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 FMB920 to switch between Vehicle on Stop and Vehicle
Moving modes see section 5.4.
FMB920 has 6 different modes. Operational logic is shown in Figure 19.
If home operator will be written to roaming operator list any part, it will be
detected as home operator, not roaming.
