4.1 SMS commands
The SCOM-100 unit accepts text SMS commands to configure operational parameters,
control the unit’s operation modes, and control the unit’s outputs. Several commands
can be packed in one SMS message.
An SMS command has the following structure:
XXXX,A..A,..,..,Z..Z
XXXX:
Command identification number 0000-9999
A..A, Z..Z: Command parameters
The comma character (‘,’) is used as a separator in the command structure. The
semicolon character (‘;’) is used to separate more than one commands packed in a
single SMS.
4.2 Naming the unit
You can specify a unit name for identification purposes. The unit name will be used in
several device’s SMS transmissions and responses. The command to name the unit is:
0300,My SCOM-100
0300:
Command ID
My SCOM-100:

Use your mobile phone to edit an SMS containing the above command. Type in the
characters without any spaces between except in text strings (eg. The name ‘My
SCOM-100’ may contain spaces). Send the SMS to the SCOM-100 mobile phone
number of the SIM. You will receive an SMS with the following response:
COMMAND PROCESSED OK
indicating that the device’s name is configured.
4.3 Configuring a digital input for alarming
A digital input can be configured to initiate an alarm SMS transmission after a signal
change. The following selections can be made:
1. Give a name to the digital input. This name will be attached to the alarm SMS if the
unit answer mode is verbose.
2. Configure the signal transition desired to initiate the alarm SMS by selecting
between a positive (0 to 1), a negative (1 to 0) or any transition.
3. Specifying a delay time for alarm annunciation. The signal change must persist
during this delay period in order to initiate an alarm SMS.
