How do I configure the EST4 IPv6 network for multi-panel communication?

The EST4 network is a self-configuring IPv6 peer-to-peer system that automatically negotiates between nodes upon power-up [1](Page 2). While it features plug-and-play setup, you must use the 4-CU (Configuration Utility) to identify nodes and enable communication ports. 1. Install SFP Modules: Insert 4-NET series SFP controllers into the slots on the 4-CPU or 4-NET-AD modules to define your media type [1](Page 1). 2. Wire the Network: Connect the eth0 and eth1 ports between nodes; connections can be made eth0 to eth0 or eth0 to eth1 [1](Page 154). 3. Collect MAC Addresses: Record the unique MAC address from the product label of each node, such as the 4-CPU or 4-ANNCPU [1](Page 48). 4. Configure 4-CU: Enter the MAC addresses into the 4-CU software so the system can identify each node on the network [1](Page 48). 5. Enable Ports: Use the 4-CU to manually enable the SFP ethernet ports (eth0/eth1) for each node to allow data transmission [1](Page 154).
