Why doesn't my serial ENET interface show up in the NI Ethernet Device Configuration utility?

Allow at least 90 seconds for the serial device server to complete its power-on self tests before launching device configuration or clicking Refresh.

Communication between the NI Ethernet Device Configuration utility and the serial device server is not guaranteed. Though unlikely, it is possible that the communication gets lost in the network. Click Refresh more than once before concluding that the device is not discovered.

Verify that the serial device server shares the same subnet as the computer running the NI Ethernet Device Configuration utility. The NI Ethernet Device Configuration utility cannot communicate with devices through gateways on the network and will not discover devices on another subnet.
