TMT250 Features settings
Over Speeding[edit | edit source]
This feature is used to prevent the driver from exceeding fixed speed and inspects the driver if needed. When vehicle speed exceeds maximum configured speed value the scenario is activated, and a record is generated. Scenario is activated until speed value decreases below the set parameter value.
Alarm[edit | edit source]
This function can only be triggered by the configured button. When the alarm is triggered, an event with IO ID 236 is generated. Eventually an SMS will be sent informing user about the event. A call possibility is also available if desired number is selected near Call to parameter. In addition, users are allowed to configure event priority. Two options are available - Call where voice call comes first and Record where data transmission to servers will be prioritized over a voice call.
ManDown[edit | edit source]
This feature gets current accelerometer data and calculates angle between offset positions. Currently there are two positions: horizontal (when device is in horizontal position and alarm button is on top) and vertical (when device is in vertical position and magnetic USB connector is facing up). Scanning is performed each second. When calculated angle exceeds configured threshold for configured timeout, then an event with I/O ID 242 is generated. SMS and/or call event takes place, if it is configured.
Event Notification[edit | edit source]
The purpose of this function is to notify any alarm events by sending an SMS message to up to 5 receivers and to call up to 5 pre-defined numbers.
At least one of the following has to be selected for this feature to work - Alarm, ManDown or Movement Event. In addition, at least one SMS Number or one Call Number has to be configured.
Movement Event[edit | edit source]
Movement Event scenario makes an eventual high priority record (and sends an optional SMS) when device is stationary or in motion (depending on configured "Mode") for set Timeout (added to "Movement Start/Stop Delays" accordingly).
Timeout is a configured amount of time (in seconds) after which an eventual high priority record is generated.
Additional Features[edit | edit source]
User ID feature allows users to send custom number as AVL ID 854 parameter.
