Changing Settings
IP Security (IPsec)
Configured in [TCP/IP]
IPsec is a set of standards for encrypted communication over the Internet. It provides effective
security for both wireless and wired LANs. To use this function, you must enable IPsec in the
network settings of your computer. When IPsec is employed, only transport mode is supported,
and 3DES or AES encryption and SHA1 authentication are used. Note that the IP address of
the computer for communication with the transmitter must be entered in [Destination address]
on the settings screen.
Directory Structure of the Target Folder
Configured in [FTP server]
Selecting [Camera] automatically creates a folder structure matching that of the camera's (such
as A/DCIM/100EOS**) in the server's root folder for image storage. If you have created a
subfolder in the root folder by changing the [Target folder] setting, a folder structure such as A/
DCIM/100EOS** is automatically created in that folder for image storage.
Selecting [Default] will use the root folder for image storage. If you have created a subfolder in
the root folder by changing the [Target folder] setting, images are saved in that folder.
Overwriting Files of the Same Name
Configured in [FTP server]
When the transmitter is configured to prevent overwriting
If there is already a file of the same name in the target folder on the FTP server, a suffix
consisting of an underscore and a number is appended to the new file's name. For example:
IMG_0003_1.JPG.
When you resend images if initial transfer fails
Even if the transmitter is configured to overwrite files of the same name, if you resend an image
file that could not be transferred initially, the existing file may not be overwritten in some cases.
If this happens, a suffix consisting of an underscore, a letter, and a number is appended to the
new file's name. For example: IMG_0003_a1.JPG.
Passive Mode
Configured in [FTP server]
Enable this setting in network environments protected by a firewall. If an Error 41 occurs
("Cannot connect to FTP server"), setting passive mode to [Enable] may enable access to the
FTP server.
