Reporting Protocol (PROT)
The AT200 supports various reporting protocols (data packet formats). Protocols used by
other devices are implemented for compatibility with existing systems. To take
advantage of the full AT200 feature set, the specific AT200 protocol “K” is recommended.
Documentation for each of these protocols is available on request from Astra Telematics,

Reporting Interval / Event Settings:
Distance Reporting Interval (DIST)
Distance based reporting interval in metres. This feature can be disabled by setting
Minimum Distance Moved to zero. Default is 5000.
Heading Reporting Threshold (HEAD)
The objective of this feature is to provide a vehicle trace which closely follows the actual
route, but with the minimum of position update reports. In broad terms, the system
provides fewer updates whilst driving in a straight line (e.g. motorways), but increases
the number of updates whilst negotiating corners (e.g. city/town driving). Heading based
reporting can be disabled, by setting HEAD to zero. Default is 45 degrees.
Stationary Timed Message Interval (STIM)
This parameter defines the maximum time interval in minutes between position update
reports whilst stationary. The appropriate value for Stationary Timed Interval will depend
on the user application. Setting the Stationary Timed Message Interval to zero will
disable time based reports whilst stationary. Default is 60 minutes.
Journey Timed Message Interval (JTIM)
This parameter defines the maximum time interval between position update reports whilst
in a journey. The journey mode is dictated by the IGNM setting, as below:
<IGNM>
Journey Detection Method
0
GPS speed
1
Digital input 1
2
Digital input 1
3
External Voltage
The appropriate value for Journey Timed Interval will depend on the user application.
Setting the Journey Timed Message Interval to zero will disable time based journey
reports. Default is 2 minutes.
Journey Timed Message Interval (JSEC)
The journey timed reporting interval may be entered in seconds using the JSEC
command. Default is 120 seconds.
Idle Mode Timed Message Interval (ITIM)
This parameter defines the maximum time interval between position update reports when
a vehicle is idling. Idling mode is initiated after a period of stationary time (see IDLE
parameter) whilst the ignition is on. Setting the Idle Mode Timed Message Interval to
