T.2.4.5 Is the firewall feature activated?

Cause

When Microsoft Windows XP Service Pack 2 is used and the Transfer Tool starts, a message appears to show that the operation is blocked by the Windows firewall.

Solution

You can continue the transfer process by canceling the blocking. However, if you transfer data to two or more display units, you need to select [PASV] for [Communication Port Settings] in the [Transfer Settings] dialog box, or disable the firewall feature.
