Ethernet Shield and Arduino DUE connection

I was connecting the Arduino DUE with the Ethernet shield but without connecting IOREF I wasn't able to communicate to DUE using LAN but in the Sechmatic of Ethernet Shield I didn't see any connection to IOREF. May I know any suggestions?

That should not be to hard but I do not what you have, post an annotated schematic showing all parts and connections. Also be sure to show all power and ground. IOREF: This is a voltage corresponding to the i/o of that board, for example an Uno would supply 5v to this pin, but a Due would supply 3.3v. Sending a signal to this pin does nothing.

Can I get the schematic? I am referring to the Schematic that I got from the website of the Ethernet shield there is an IOREF point in the schematic but it is not connected anywhere I have seen the Layout of the PCB also there also I can't able to find it.

I am not worried about the schematic for the shield, posting a link to the technical information generally solves that. i am concerned on how you have wired the boards together. Without a link to the shield I assume it is board that you connect with jumpers.

yes, I have connected with the jumper wires to understand what points are required for Arduino and ethernet shields without direct connection. but I need to understand why IOREF is required to enable communication through LAN because the connection is not in the schematic. and I need a schematic of the updated IOREF point as I can't able to see the usage of the IOREF point in the Schematic.

This is a voltage corresponding to the i/o of that board, the UNO, Mega, etc would supply 5v to this pin, but a Due would supply 3.3v. This is the reference voltage for the processor I/O system. This pin controls nothing, placing a signal on this pin does nothing.

okay TQ I understand. now i will continue
