For direct communication using the electrical ETHERNET port, connect a 10/100 BaseT cross-over network 
cable  between  the  computer  and  the  unit,  as  shown  in  Figure  24.  The  network  cable  should  have  the 
following pinout:  
 
TABLE 29: Cross-over network cable pinout.

In the direct communication with the unit, it is necessary both the computer and the unit connected on the 
same local network. To do so, configure the computer network connection according to the unit IP address, 
and network mask, as the following example. 
RT430 IP address, broadcast and network mask configuration:
