5.10.3.1. FTP user selection
The transducer has two FTP server user accounts protected by individual passwords:
●
user: „ admin ”, password: " admin ” - access to read and write the files
●
user: „ user ”, password: " passftp ” - access to read only the archive files.
The FTP 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 FTP 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 " passftp ”.
Internet browser can be used as a rudimentary FTP client. By entering the IP address of
transducer with the “ftp” header into the address field, e.g.: ftp://192.168.1.30 it is possible to browse
and download archive files from the Internet browser directly.
