Product description

The Telit GT863-PY terminal is a complete encased modem solution for wireless m2m applications.

GT863-PY is the new generation of Telit terminals based on the quad-band and RoHS compliant GE863 core engine incorporating additional and new features.

The GT863-PY featuring the embedded Python™ script interpreter provides the possibility for running customer programs inside the modem, thus making the terminal a complete self-contained application platform for customer solutions. Programmable I/O ports and the ­IIC-Bus can be used for monitoring external signals, connecting sensors, and switching external devices. The GT863-PY is capable of communicating through all traditional data services provided by GSM/GPRS networks. As with all Telit modules, the GT863-PY offers jamming detection functionality allowing the unit to sense attempts to disrupt the GSM communication by interference with the GSM signal.

Directly controlled by a standard serial RS-232 interface and offering a broad supply voltage range (9–24V DC), the GT863-PY is a universal solution for most low-volume m2m and mobile data applications.
