Scm And Windows Firewall - National Instruments NI DIDS-2103 User Manual

3.2.2.4 SCM and Windows Firewall

After installing SCM, if Windows Firewall is enabled, SCM should be added to the list of Allowed Programs to
communicate through the Windows Firewall. Since SCM must communicate with the DI Driver System via a Ethernet
LAN port, it is important that Windows Firewall be configured to allow SCM, and its associated programs, access to
the network. SCM and its associated programs use UDP, TCP/IP, and FTP protocols. Sometimes, certain Windows
settings prevent SCM from being added to the Allowed Programs list. The Allowed Programs list can be checked by
following the instructions below.
The PC used for interfacing with the DI Driver System may have the Windows Firewall turned off. In this case, the
Allowed Programs list is not applicable and does not need to be checked. If the Windows Firewall is turned on, it
may be possible to turn it off, if allowed by the network administrator.
Some PCs may use a different software firewall other than Windows Firewall and will need to be configured properly
to allow SCM to communicate with the DI Driver System IP address via UDP, TCP/IP, and FTP protocols.
Checking the Windows Firewall Allowed Programs List
The Windows Firewall configuration can be opened by going to the Windows Start menu and entering "Windows
Firewall" in the search field.
Select Windows Firewall from the Start Menu search results to open the configuration window. The screen shot
below is a general representation of what may be seen if the Windows Firewall is on.
