7.4 Firewall
It is important to disable all Firewalls on the computer. Third party firewall from Norton,
McAfee or other companies can completely disable the operation of the DAQlink III unit.
Typically the Firewall will allow the “ping” command to operate, but will block all other
commands and messages.
There is a built in Firewall with Windows XP. This should be disabled. Go to the
Advanced Menu of the Local Area Properties and disable the Firewall.
Typical Firewalls will ask if the program should be “blocked”, always select “Unblock
this program” if asked.
