The Robotino is equipped with two Ethernet ports — one for the embedded PC and one for the microcontroller.
 
        Ethernet port to the embedded PC
Function
            You can establish a direct connection from your PC/notebook to the control computer in
            the Robotino via the Ethernet port to the embedded PC. 
On delivery, the
            embedded PC's IP address for this connection is 172.27.1.1. Since the embedded PC does
            not support DHCP, you will need to configure a static IP address for your network card,
            for example 172.27.1.100 with subnet mask 255.255.0.0, before establishing a connection
            with the Robotino.
          
 
        Ethernet port to the microcontroller
Function
            You can establish a connection from your PC/notebook to the microcontroller via the
            second Ethernet port. 
On delivery, the microcontroller's IP address for this
            connection is 172.27.254.254. The microcontroller does not support DHCP either. This
            means that you will need to configure a static IP address for your network card for the
            connection to the embedded PC, for example 172.27.1.100 with subnet mask 255.255.0.0,
            before establishing a connection with the Robotino.
