OEM. If the connected network does not have a DHCP server, the address stored in the default IP address is assigned. If the E-DIO24-OEM is directly connected to a Windows PC or other host that supports link-local addressing, a link-local address is assigned. A link-local address is valid only for communications between the E-DIO24- OEM and the PC to which it is connected. -
