7.3 Set Geo-Fence There are two user-definable buttons on the Mini-MT. The first button is factory-defined
to set a geo-fence. Depressing the Geo-Fence button will place a half-mile radius circular
geo-fence around the Mini-MT. When the Mini-MT exits the geo-fence an alert message
will be sent via SMS message to the SMS Destination Address defined in the
AT$SMSDA field. (Messages and alerts can also be sent via GPRS packet data. The
user has the ability to control the IP and port that the packet data is transmitted to)
The factory default configuration of the Mini-MT will not have any SMS Destination
Addresses configured and will not be capable of generating SMS messages for Geo-
Fence events.
7.4.1 User-definable Button “”
The Mini-MT “” button is user-definable through the event engine. The default state
is to configure a ½ mile radius geo-fence at the current location.
7.4.2 User-definable Button “>”
The Mini-MT “>” button is user-definable through the event engine. This button
function is not defined from the factory.
The Mini-MT is capable of dialing an emergency number (AT$EMERNUM) and a
dispatch number (AT$DSPATCH). The default emergency number in the Mini-MT is
“411.” The provider should reconfigure this number to the correct emergency number for
the region the Mini-MT will operate in.
To set the emergency number to “911” enter the following text in the terminal window:
AT$EMERNUM=“911” <enter>
AT&W <enter>
The first command sets the emergency number to 911 and the second command saves the
setting.
