Please read first this Article:

Getting started with Arduino and WIZ820io --> [1]


It uses the same source code exept we use here an Wiznet W5100 Chip intead of W5200 so only config TCPIP needs to be changed.

The usage of Easy TCP/IP in combination with that example is also the same.

Source Code:

The difference is only this part in the Bascom source code: 


'Here you need MAC address, the ip address you like to use, subnet mask, gateway and localport
 Config Tcpip = Noint , _
 Mac = 1.1.94.127.1.255 , _
 Ip = 192.168.2.254 , _
 Submask = 255.255.255.0 , _
 Gateway = 192.168.2.1 , _
 Localport = 1000 , _
 Tx = $55 , Rx = $55 , _
 Chip = W5100 , _
 Spi = 1
