I just added a serial device server to the network, but it does not show
up in NI Ethernet device configuration. What is the problem?
Allow at least 15 seconds for the serial device server to complete its
power-on self tests before launching device configuration or clicking
Refresh.
Communication between NI Ethernet device configuration 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 the device is not discovered.
Verify that the serial device server shares the same subnet as the computer
running NI Ethernet device configuration. NI Ethernet device configuration
cannot communicate with devices through gateways on the network and
will not discover devices on another subnet.
