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.

/:root

MEMCARD: Memory card directory

EM:EM file memory directory

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).
