Interoperable Self-Installation Developer Center
Create devices that install themselves—without a network management tool!

With the Interoperable Self-Installation (ISI) protocol, LonWorks devices can self-install automatically or at the push of a button. If you're a LonWorks device manufacturer, you'll find this new application-layer protocol can open new markets for you—including the fast-growing, price-sensitive sensor/actuator mass market.
The ISI protocol is also the only interoperable self-installation tool model that can transition to a managed network, where a network management tool configures all devices.
Features
- Supports up to 32 devices for simple networks
- Supports up to 200 devices for networks with a simple domain address server
- Leverages LonMark standards to allow devices from different manufacturers to work together
- Enables network isolation for power line networks
- Allows simple or complex connections among devices
- Installs simply and reliably, even if many devices are off when new ones are added
- Operates on top of the ISO/CEA 14908-1 Control Network Protocol
- Can transition to a managed network
Documentation
- The ISI Developer's Kit datasheet
- The ISI Programmer's Guide describes how to use the ISI library to create an ISI device.
- The ISI Protocol Specification describes the ISI protocol.
- The ISI eTraining provides an introduction to ISI.
Development
You can develop ISI devices with the NodeBuider FX Development Tool, the Mini FX Evaluation Kit.or the ShortStack FX Developer's Kit. You can download and install the ISI Developer's Kit 4 to get the latest updates to the ISI libraries. The ISI Developer's Kit includes an ISI library that manages the ISI protocol and simplifies ISI device development. ISI Example Neuron C Applications are available for download. ISI examples are included with the NodeBuilder FX, Mini FX, ShortStack FX, and Mini EVK products, and are made available separately for NodeBuilder® 3.1 Development Tool users.
Licensing
ISI is a licensed protocol. The NodeBuilder FX, Mini FX, ShortStack FX, Mini EVK and ISI Developer's Kit products include a royalty-free license for using the ISI library with Echelon transceivers and processors.
- If you want to produce devices that incorporate the ISI library and Echelon transceivers, you'll need to sign a Revision J or newer OEM License Agreement in order to receive a royalty-free license.
- If you want to create your own implementations of the ISI protocol, you'll need to sign an Echelon ISI Protocol License Agreement.
To get a copy of either license agreements, please contact your local sales representative.
