Setting Up Password Protection - Siemens 7XV5655-0BB00 Manual

Setting Up Password Protection

The Serial Modem features extensive password protection. This protects the called
modem (substation modem) from unauthorised external access. The password is
always transmitted encrypted via the Ethernet.
Password protection can only be configured after entering the master password in the
password configuration mode with the terminal program via the serial interface, i.e.
locally.
Note: The connection via the serial RS232 interface can only be established with the
baudrate and data format currently set in the modem.
Activating Password Configuration Mode
You enter the configuration mode the first time by entering ATP<Enter>, i.e. no master
password has been assigned yet. If the master password has been changed, the new
master password must be entered.
ATP<Enter>

Changing / Deleting the Master Password
By entering ATZ="new master password", you can change the master password.
ATZ=master
ATZ=<Enter>
If the master password has been forgotten, the device must be sent in.
