The GX111 has an update function. However, an update should only be performed to solve wrong behaviour. Every
update process has risks (e.g. cancellation during the update, etc.). It must be assumed that the product must be sent
to the manufacturer after a defective update process.
In the following, the most important items that you must observe when using the product are noted.
All text message answer examples are to be understood symbolically. Actual implementation may vary. The
examples should only show the information on the format and writing to be expected.
Prior to commissioning of the product, check whether it is generally suited for the intended application!
If in doubt, ask a suitable specialist.
a) General Descriptions
This product is to be used to monitor the customer's property. In case of alarm, its task is to inform the customer of it
by text message as quickly as possible.
It may monitor shock, position changes, brightness differences and temperature. In case of alarm, the GX111 sends
an alarm text message to up to 4 stored phone numbers.
The GPS receiver is used to determine and monitor GPS zones („GeoFence"), i.e. a place or area where the product
may be present.
The product is designed for maximum battery life. The regular condition is sleep mode, where only the configured
sensors are active. They wake up the module to send text message alarms if a threshold is exceeded.
Apart from this, the module will wake up every 24 h, e.g. for 15 minutes (default) and will check for any text messages
received. Upon receipt of a text message, the „ONLINE" timeout is reset and can be considered further. During this
time, e.g. the current position can be determined. For this it is possible to have a link to OpenStreetMap.org (open-
source map provider) sent by text message command.
Furthermore, the product may also record and save (track) the current GPS position. These saved data can be read
by USB.
