IT-2000
PROGRAMMING AND MANAGEMENT WITH SMS TEXT MESSAGES
USE OF THE SMS TEXT MESSAGES FOR REMOTE PROGRAMMING
As already explained, IT-2000 is completely configurable by means of SMS text messages.
To program the system, the user must send a text message suitably formatted.
A command can be composed by more fields separated by a space character: each field is composed by a
command id, an optional command index, an operator and a value (
ID[.index]operator[value]
)
The first field of a command text must be the password declaration in order to authenticate the user access
(e.g.;
PWD:000000
) .
The following operators are recognized by the system:
Operator
Name
Example
:
Declarator
PWD:111111 This statement declares the password value
=
Assignment
TEL.3=1234 This statement assignes the 123456 value to the third phone
number
?
Request
PFX? This statement asks the system to return the PFX parameter
value
After receiving a SMS, the system will execute the command(s) and will answer with a SMS containing the
result of each single command.
For example, after receiving the “PWD:000000 TEL1.1=24 “ SMS, the “PWD:OK TEL.1:OK” SMS will be
returned.
A wrong field will be answered with the *FAIL* indication while a not recognized field will be answered with
the *?* indication.
Commands are CASE UNSENSITIVE and may be written either in capital letters or in small letters.
WARNING:
incoming messages exceeding 64 characters will be ignored and will be not acknowledged.
SIM CARD AND PIN CODE
The system normally works with SIM cards without the PIN code. If the SIM card cannot work without the
PIN code it must programmed to the
1234
value: the board will use that code to use the SIM card.
USE OF THE INTERFACE WITH A TELEPHONE EXCHANGE SYSTEM
When the IT-2000 is connected to a telephone exchange, the number generated by the alarm system may
contain a prefix that must be skipped when forwarded to the GSM network (eg: the 0 065487954 number
must exit as 065487954).
This can be done through a suitable system setup (see the relevant paragraph).
NOTES
To avoid damages, when working on the PSTN line, IT-2000 doesn’t generate any ring signal at the
occurrence of an incoming call from the GSM network.
At system reset, all SMS messages are associated to the first telephone number (if any): to modify
this setting it is necessary to send a suitable command to the unit (smstel.x=0)
RESET (DEFAULT) BUTTON
To return to the initial default programming condition the system must be turned off (disconnecting supply
and battery) and then turned on with the RESET KEY (SW1) pressed.
The are two type of system reset:
1° PASSWORD RESET:
if the key is pressed for about 5 seconds only the system password is reset
2° TOTAL RESET:
if the reset key is pressed for more than 10 seconds the system will resume the default
configuration
REMARK: during reset the RED LED is turned ON, the GREEN LED blinks and, only for TOTAL RESET, the YELLOW LED
gives a short flash.
DIAL TONE
IT-2000 is able to generate either a continuous dial tone (default setting) or a pulsed dial tone.
To change the setting a suitable SMS command must be sent (PULSE=on/off).
