Check the operation mode of the NPort and change it to Real COM Mode or Host Based / Driver Mode.

Check if the TCP port numbers 950 to 981 are occupied.įor example, for Port 1 of an NPort 6000 Series device, go to the Log, Monitoring and Warning -> System Monitoring -> System Status -> Network Connections page and confirm that TCP ports 950 and 966 are in the LISTEN state.Check to ensure that the filter rules in your firewall do not restrict the TCP port numbers 950 to 981.Open the web UI of the NPort by entering the IP address of the NPort into a browser and ensure that the IP address of the host is included in the Accessible IP List of the NPort.įor example, in the NPort 6000 Series, go to the System Configuration - > Accessible IP List page and check the Accessible IP list as shown below:.Note: Since the Search function in the search utility searches by MAC addresses and not by IP addresses, all NPorts connected to the host/LAN will be located, regardless of whether they are under the same subnet as the host or not.
