Ethernet Relay Software Development

The Digi Connect ME firmware is built into the Ethernet module allowing you to login to the device and access powerful network communication options.  Though it does not offer a web browser interface (this feature can be found on the Web Relay models), it does offer many powerful connectivity options for advanced networks.  ME firmware supports Virtual COM Port Ethernet Communications, Direct TCP/IP communications, or direct communication to  ME firmware is only capable of handling only one of these communication options at a time, but can easily be reconfigured if you prefer to change how you communicate.

Ethernet Relay for Advanced Users

Advanced users may want to employ other communication protocols to speak the the Ethernet Relay Controller. NCD Ethernet Relay Controllers can also be controlled using Telnet. I.P. Addresses and are automatically or manually assigned. NCD Ethernet Relay Controllers also support security protocols such as Shared Key, WEP, WPA, and Cisco LEAP with support for WEP, TKIP, and CCMP data encryption.
