FTP Server Function Details Section 4-2
4-2 FTP Server Function Details
4-2-1 File Types
The file system in the CPU Unit that can be accessed by the Ethernet Unit
includes files in any Memory Card mounted in the CPU Unit and files in the
EM file memory. The directory tree is shown below.
A connection will be initially made to the root directory.
Note 1. The date of the MEMCARD directory displayed for ls or dir commands in
the root directory will be the date of the file system volume label.
2. The login date will be displayed for EM files and for MEMCARD if a volume
label has not been created.
4-2-2 Connecting to the FTP Server
The host computer must connect to the FTP server before the FTP server
functions can be used. The login name and password set in the Unit Setup will
be used when connecting. The default FTP login name is “CONFIDENTIAL”
and no password is required.
The FTP server in the Ethernet Unit can connect to only one client at a time. If
a client attempts to connect when the FTP server is in use, a message will be
returned and connection will be refused.
Note When general-purpose FTP software is used, files can be transferred and
read using a graphical user interface similar to Explorer.
Login Name and Password Setting
The default login name for FTP is “CONFIDENTIAL” and no password is set
for the default login, so login is possible by simply entering “CONFIDENTIAL”
as the login name. A user-set login name and password can also be set in the
User Setup (CPU Bus Unit System Setup).
