7. Timing criteria
The Default timing programming settings are:
T
0003
R
020
C
010
T
=
Time between each SMS message with GPS coordinates that the device will send
when it is in the “Tracking” mode, and also the timing that “Geofence” feature will
use for its position checks.
R
= Number of times the GPS position SMS messages is sent while in “Tracking” mode.
C
=
This is the time delay between Checking for any new SMS messages when
the Tracker is in Power Save mode.
7.1 Power Save Mode-OFF:
If Power saving mode is switched
OFF
the SMS messages will be processed
immediately, but as a consequence the battery will last much shorter. With the 700mA
internal battery, it will last about 10-12 Hrs.
7.2 Power Save Mode-ON:
In above example a message
1234-R-TRK
is sent in the active Time (about 2 min.) of
the Tracker and a response message will normally be received in about 30 seconds.
(Depends on the mobile network provider and their associated SMS message servers)
The second SMS command
1234-T
can only be processed in the next active time after
the Power Save period, and the entire device is turned off for 10 minute periods (Or
whatever the “C” time is programmed by the user).
NOTE: For a general idea of how Power saving mode saves battery life, when a SMS is
sent with GPS coordinates every 15 min (e.g. Tracking mode activated with a “T” time of
15 min), the internal battery will last about one week. Depending on other parameter
settings the battery life could even last for months.
