Password Protection
To prevent unauthorised access to the menus, the V100 has three levels of password protection; Read-
only, Read/Write and Superuser.
The serial number is used in the password mechanism. By default, the units have no passwords
configured, and there is no password required to access the supervisor port. The user can configure two
levels of password through the SYSTEM menu. The first is for read-only (RO) access - the second is for
read-write (RW) access. Once a RW password has been configured then any future access to the
supervisor port (either local or remote) will encounter a request for a password before allowing access. If
the RW password is entered, then the supervisor port works as before with full management functionality.
If the RO password is entered, then the menu system is presented, but any changes made to the
configuration will not be saved - also access to the debug menus and debug mode (and other shortcuts)
are prevented. The RO password is only effective once the RW password is entered.
Password entry is in a conventional format, with the entry being asterisked out and password setting
requiring re-entry for confirmation. The password is case-sensitive. If the user forgets their configured
password there is a backdoor mechanism to get them back into their units. This backdoor is the
"superuser" password - it is unique for each V100, and consists of an encrypted key based on the serial
number. Once entered, the user is given normal read-write privileges to allow him/her to set the RW
password to something that they can remember! A superuser password can only be supplied by Vocality
International on the following telephone number:
+44 1483 813120
Please be prepared to supply your name, company name and the serial number of the unit.

The FLASH loader utility – FLASH.EXE - will not work straight away if a RO or RW password has been
configured. The FLASH loader has been updated to request the user for a password. If no password has
been configured or the unit is running an older revision of software that does not support passwords, then
leaving the password field blank will allow programming to work as before. The utility presents separate
fields for local and remote passwords to fully support remote unit downloading.
