use the Ethernet connector for the first configuration. Or in case of 
doubt, use the serial port for this. 
The configuration of the WLAN parameters should follow in a later 
step. This is especially the case, if encryption or certain other 
parameters require certain configuration.

The connector for Ethernet is the usual RJ45. Simply connect it to your 
(switching) Hub. When the connect is done the Link LED on NetCom 
(yellow) will light. When data traffic occurs on the network, this LED 
will blink. It depends on your network whether a 100Mbit or a 10Mbit 
connect will be established. A 100Mbit net causes the Speed LED on 
NetCom (green) to light, otherwise it will remain dark.

There is one set of 4 Dip switches to configure the operation mode of 
the NetCom Device. This switch is the Master configuration for each 
serial port. All ports operate in the same mode, unless the DIP switches 
configure for software setting. Before connecting a serial device, the 
serial port configuration must be completed. 
Warning: a bad configuration may cause serious damage in the 
NetCom or the connected device. 
To avoid these problems, it is recommended not to connect a device to 
the serial ports in the first installation. The serial ports should be 
configured for RS232. This is done by setting the DIP switches like this 
example.
