Connection to LAN 
If the control system is connected to a larger network via a hub, make sure that a 
straight (non-crossover type) Ethernet cable is used and that the cable is not 
connected to the UPLINK port of an Ethernet hub. 
Connection to PC 
If the system is connected directly to a personal computer (PC) Ethernet card, make 
sure that the cable between the C2ENET-1/-2 is a crossover type.
