When I installed it on Windows 7, communications don't work.

DAQWORX has a program that performs communication, but it can be interfered with by the Windows firewall. If a program fails to run due to the Windows firewall, you can either disable the firewall or refer to the document below to specify to "Allow a Program Through Windows Firewall." Note, if that does not work, the Windows firewall might not be the only problem. Before adjusting Windows firewall settings, check the following.

• Use a ping to check the Internet connection. If the ping fails, it might be due to HUB or IP address setting problems.
• Check whether the software is operating correctly.

If the problem cannot be resolved even after checking the above items, it is more likely to be a problem with the Windows firewall.
