I searched the device by XPortInstaller or DeviceInstaller (an utility software for XPort settings), but I cannot find it on the network.
There is a possibility that IP overlaps. First, input MAC address described under LAN connector of the device to "Assign IP" of XPortInstaller. Then, set IP address to "0.0.0.0" (the condition of shipment from the factory). Or, if you use a fixed IP address, please set an IP address that is not overlapped.
If you use DeviceInstaller 3.6.0.6, after MAC address is input on "Assign IP", select "Obtain an IP address automatically", and check DHCP, BootP, Auto-IP and Clear Gatway. Then, press "Assign". If you use a fixed IP address, after MAC address is input, select "Assign a specific IP address" and set an IP address.
