Device Watchdogs
The Picotrack has different integrated watchdogs. They automatically check the functions of the
device and generate resets as soon as they recognise any malfunction. Malfunction could occur
due to internal problems of the device, problems related to the GSM connection, problems with
the GPS reception and many more.
This watchdog concept ensures that the Picotrack can automatically return to stable operation if
necessary. Control of the watchdogs by the user is not necessary.
If the watchdog has to restart the device, it may happen that some of the position messages and
respectively events are not logged and as a result they are not transmitted to the tracking server.
Device-based wireless positioning
The device can be configured in order to get a localization obtained by the GSM module, in case
that the GPS has some difficulties providing a valid fix. Of course this position will be less
accurate and take a bit longer than the
standard way by GPS module, therefore this functionality
has to be considered as a fallback for the GPS.
Device Installation on Board
In order to protect your goods from theft and vandalism the device should be installed in a
location where it is well-hidden. Please install the device in a suitable, dry location, not in contact
to radio and audio frequency interference or hot parts of the good. Be aware to observe ESD
(Electro Static Discharge) protection measures. When installing the device consider that antennas
are integrated, this means it must be installed in a place with a minimum distance of 7 cm to any
metallic components of the good in each direction. In order to optimize the quality of the signal
received, the surface of the internal GPS internal antenna must be installed while looking at the
sky.
