programmed with function 26. The SMS which is then sent contains information on the
current settings (transmission period and 4 telephone numbers to be notified, also for test
transmission purpose). For the module to return the SMS, the SMS centre number must be
programmed (function 02).
Note:
The message sent to the module may contain just the SMS password, but it can also
be longer than the password (the password can be part of a longer word). It is
important that the password be inserted in the initial part of the message text (among
the first 32 characters). This feature makes it possible to load a verbal description of
the performed operation into the memory of the telephone from which the SMS will be
sent. Thus the user does not need to remember the passwords and their
corresponding functions. Only one control password can be sent in one message.
Sending an SMS without any password will cause no reaction of the module.
The received message will be deleted, and the telephone will be ready for reception of
a next text message.

ODULE PROGRAMMING
For the module to operate properly, corresponding parameters must be programmed.
The programming is possible by means of a stationary telephone capable of generating
DTMF signals, or by using a PC computer and the DLOAD10 program (version 1.00.17 or
later).
10.1 DLOAD10
PROGRAM
The GSM LT-1 module is delivered together with the DLOAD10 program which enables the
module to be programmed from a computer. The program is designed for IBM PC/AT
compatible computers. It works in any computer hardware configuration in the
WINDOWS
(9x/ME/2000/XP) environment. It is recommended that the program be installed on the
computer hard disk.
The GSM LT-1 module communicates with the computer via the RS-232 interface.
To connect the ports, use the cable made as shown on Fig. 6 (the cable symbol acc. to
pricelist: DB9F/RJ-KPL).
