Firmware Update
The firmware of the i-modul Modem 336 LL 3.0 can be updated to add further functions
to the i-modul Modem 336 LL 3.0 or to improve the existing functions. A firmware up-
date can be performed with the help of a terminal program that supports ASCII uploads
(e.g. TeraTerm).

Damage of the serial interface!
A possible direct connection of the serial interface of the
i-modul Modem 336 LL 3.0 with a typical RS232 interface
of a PC overloads components of the module due to the
higher voltage levels.
Use a level converter (e.g. MAX232) to adjust both inter-
face types correctly.
