[FTP/HTTP Authentication] Setting (p. 214).
Anonymous authentication allows unrestricted access to the HiLogger's FTP server by
all network devices.
To restrict access to the FTP server, enable FTP/HTTP authentication and set a user
name and password.
We recommend restricting file access with a user name and password to avoid unautho-
rized use.
• The FTP server of the HiLogger allows only one connection at a time.
More than one PC cannot access the server simultaneously.
• If no command is sent from a PC for more than one minute after connect-
ing to the FTP server, the FTP may disconnect the PC. Reconnect the
FTP.
• The FTP connection may fail after disconnecting and attempting to
reconnect. In this case, disconnect again and wait for one minute before
reconnecting.
• During real-time, auto, or manual saving, and when deleting files, creat-
ing or deleting folders, or renaming, formatting, or loading files on the
HiLogger, only file transfers are possible from the FTP client.
• If an FTP transfer is writing to removable storage when auto saving starts
or numerical calculations are saved, FTP operation is suspended during
data saving.
• When measurement ends during an FTP transfer, the transfer may be
suspended during data saving.
• Before inserting or removing a removal storage, terminate the FTP con-
nection.
• Although the HiLogger's removable storage can be externally accessed
using FTP, avoid other HiLogger operations such as using telnet at the
same time. Otherwise, unintended operations could occur.
• With IE, the refresh date of files may not match those of the main HiLog-
ger.
• With IE, previously obtained data can be retained in temporary internet
files, and may be reloaded in place of the latest data. If the HiLogger's
data has been refreshed, restart IE before using FTP. (A free alternative
to IE is FFFTP.)
