Selecting a Password-Protected Serial Modem

Selecting the Remote (Substation) Modem
After you have selected a password-protected Serial Modem, the message
"PASSWORD:" appears to prompt you to enter the password.
Entering a Password
To establish a link, you must enter one of 9 user passwords and confirm with "Enter".
Transmission is always encrypted.
If the correct password has been entered, the connection with the device on the remote
modem is established.
Note: The master password is only for activating password configuration mode; it does
not permit connection setup.
Entering an Incorrect Password
If you enter the wrong password, the message "WRONG PASSWORD" is displayed.
You have two more goes at entering the password.
If a call from an IP protected modem is not accepted, the message "ACCESS DENIED"
is displayed and the password blocking time starts (register S82).
Note: A repeated call will not be accepted until the password blocking time has elapsed
and the correct password has been entered.
