4 Service and SW / Firmware Update
The RS232 serial interface on the Terminal used for the communication with a PC can also be
used to update the
Telit GT863-PY Terminal firmware (Software).
The firmware update can be done with a specific software tool provided by Telit that runs on
windows based PCs.
The update procedure requires switch-on the Terminal at a prompt within the running update tool.
Thus, the power supply line shall be disconnected before the launch of the update tool on the PC
and prepared for re-connection.
NOTE: Switching OFF the GT863-PY by disconnecting the external power supply line requires to
wait enough time (depending on the HW version!) that the load capacitor of the DC/DC converter
inside the GT863-PY discharges so that the module inside goes to OFF condition.
