The 105U radio protocol is designed for very efficient radio usage, with configurable communications based on event reporting (I/O change), update times and/or poll response. Other features are:

• high security data encryption
• automatic acknowledgment and error-correction,
• peer to peer addressing, and
• mulitple path routing

The 105U-G modules also have eight on-board discrete I/O, individually configurable as input or output.

Network configuration is performed with easy-to-use free software. I/O links are configured between different modules in the network.
