SMS Remote Configuration and Management of the Universal 2G GSM
If using the Universal 2G GSM with an emergency telephone other than the Memcom or C100, the GSM can be
configured remotely and send status information via SMS to a list of authorised users.
Two types of authorised user profile can be configured:
•
Up to 4 users who have permission to configure and request information messages from the Universal GSM
•
Up to 4 users who can receive SMS information messages from the Universal GSM.
NOTE: If no numbers are set to configure then any user can remotely manage the GSM
Configuration of the Authorised User List
The authorised user list can be setup by sending the following SMS to the Universal GSM unit:
*1 # ID # conf1 , conf2 , conf3 , conf4 # dest1 , dest2 , dest3 , dest4
Command
*1
#
ID
#
conf1
,
conf2
,
conf3
,
conf4
#
dest1
,
dest2
,
dest3
,
dest4
Notes: All telephone numbers must have the international prefix e.g. +44 for UK
Example configuration message (two users):
*1#2GLIFT#+447987654321,+447123456789#+447987654321,+447123456789
Configuration acknowledgement messages
When the GSM has received a message it will check if the message is from the list of authorised numbers.
•
If the message is from an unauthorised number then it will be ignored
•
If the message is from an authorised number, and is correctly formatted, then a message reading 'ACK' will be
received
•
If the message is from an authorised number, and is incorrectly formatted, then a message 'NACK' will be received
All the messages from the GSM start with an index number followed by a #. This index number starts at 0 and will
increase to 255 before resetting to 0. This will reset if the GSM is powered down.
Example of successful configuration message:
2 # *1 2GLIFT # ACK
