Addressable TCP/IP Interface – EC400

The (EC400) is high performance, reliable and secure network infrastructure device for accessing Eaton Lon Network of intelligent addressable control panels over intranet or ethernet.

The EC400’s built in configuration server manages up to 256 IP devices on 1 IP channel without a dedicated management PC.

This unit supports DHCP even with changing IP addresses in an intranet environment. The easy to understand, diagnostic LED’s allow installers to install and trouble shoot the device without expert knowledge and dedicated troubleshooting tool.

To connect the Eaton Lon network via intranet will require a minimum of 2 EC400’s. The first EC400 must be configured as a “configuration server” and the second as a “client”

The EC400 when configured as a server requires the address list of all the EC400’s IP addresses in the network.
