The web server user names can not be changed but you can change the password for each
user - for safety reasons it is recommended to change the passwords. Changing the password is
possible only through a web page in the "Ethernet" parameter group. The passwords can be up to 8
characters. If the password is lost (what disables using the web server), restore the default settings of
the Ethernet interface e.g. from the menu:
Ethernet EthStdPa
→
→
Yes
, or by entering the
value "1" to the register 4080. All standard Ethernet interface parameters (see Tab. 17) and the
passwords of the FTP server users will be restored:
user „
admin
” → password: „
admin
”;
user "
user
” → password "
pass
”.
The session lasted five minutes opens when you log in to the web server. After five minutes a
user will be automatically logged out from a web server. The change of the group parameters renews
time to expiry of the session.
5.10.3 FTP Server
The FTP file sharing protocol has been implemented in the P30P transducers. The transducer
acts as a server, allowing the users to access the internal memory of its file system. Access to the files
is possible using a computer, a tablet with installed FTP client or other device acting as a FTP client. The
standard FTP ports are used for transferring files, "20" - data port and "21" -- commands port. A user can
change the port used by the FTP protocol if necessary. Please note, that the port configuration of the
FTP server and the client must be the same.
It is recommended to set the FTP client in the passive mode, because the connection is then
fully configured by the FTP client (a client chooses the data port). Only one connection at one time can
