Isolate the DeviceMaster from the network. Connect the device directly to the
NIC in the host system.
The default DeviceMaster IP address is often not accessible due to the subnet
masking from another network unless 192.168 is used in the network.
In most cases, it will be necessary to program in an address that conforms to
your network.
Invalid IP information may also cause the switch or router to check for a
gateway address. Lack of a gateway address is a common cause.
