2.14 User Interface
The user interface of the GT863-PY Terminal is accessible from a Data Terminal Equipment DTE
connected to the RS232 interface and it is managed by AT commands according to the GSM 07.07
and 07.05 specification and the supported commands are listed in the AT Commands Reference
Guide.
2.14.1 Switching the GT863-PY Terminal ON and OFF
In this paragraph will be explained the way to switch the GT863-PY Terminals ON or OFF.
NOTE: Switching OFF the GT863-PY by disconnecting the external power supply line requires to
wait enough time that the load capacitor of the DC/DC converter inside the GT863-PY discharges
so that the Telit module inside goes to OFF condition.
• The GT863-PY Terminal switches on automatically each time the Power Supply is
connected the first time or re-connected.
• The GT863-PY Terminal can be turned OFF by the command AT#SHDN, but immediately
thereafter it switches ON again automatically (AUTO POWER ON always enabled).
2.14.1.1 GSM/GPRS Standard Modem
It is always worth a trial to install the GT863-PY Terminal as modem on a PC in the following way:
First add it in the PC’s Control Panel – Telephone and Modem. Select from the list the “Standard
33600 bps Modem” with connection to the related COM port, then make a new “Dial-up connection
to private network” using this modem with the dial-up parameters of the GSM/GPRS Network in
use. Sometimes the parameters indicated for the use of the WAP-Browser of mobile phones (over
GSM CSD call or GPRS) will work.
Example for a GPRS connection set-up:
Under “Properties-General Configure” the initialization has to be entered in the text box selecting
“Run Script”. The parameters are examples for subscribers of Italian GSM network operators.
