ECURE ACCESS
The Xcom-SMS module protects your system with an access code in order to avoid that a third
party takes control over a system by knowing its phone number. This access code, indicated <key>
in this document, is a unique code of 6 characters. These characters can be composed of
numbers ('0' to '9'), upper case or lower case letters ('a' to 'z' et 'A' to 'Z'). The access code is case
sensitive.
As it is not possible to identify the sender of an SMS command, the access code has to be used in
the beginning of each SMS. The access code must be followed by a space in order to be
acknowledged.

It is highly recommended to change the access code to guarantee the security of your system
(see the command "newkey").
Attention, in case of loss of the code the configuration has to be repeated from
scratch using the Xcom Configurator available on the micro SD card.
Your installer may also reset the access code if necessary.
If an SMS is sent using an incorrect access code <key>, the system will send an error message in
return if it's possible to identify the sender. The error message has this format:
The number of consecutive error messages has been limited to 5. Thereafter the
Xcom-SMS is blocked during 24h before taking in consideration any new SMS.
This function prevent the system from being hacked by the scanning method which
would create important SMS costs (in reply) by the Xcom-SMS.
