OpenLCB/NMRAnet Clinics at Grand Rapids 2012

There are two OpenLCB/NMRAnet clinics at the Grand Rapids 2012 Convention:

Clinic 1 – An introduction to OpenLCB / NMRAnet S-9.7

In this clinic, we provide a beginner’s view of how the new NMRAnet S-9.7 works, and how it can be deployed on your layout. We will offer a demonstration of the capabilities of NMRAnet hardware, and how to use it.

Time: 7/31/12 9:00a – 10:00a Room: Pearl

Clinic 2 OpenLCB/NMRAnet S-9.7 for Developers and DIY

Interested in learning about the nuts and bolts of OpenLCB / NMRAnet? Thinking about making your own hardware? In this clinic, we explore the workings of OpenLCB / NMRAnet at a low level, providing the foundation for designing your own hardware and software. Topics include: the OpenLCB stack; using CAN for transport; basic OpenLCB messages and protocols; designing higher- level protocols; best practices for hardware and software design.

Time: 8/1/12 1:00p – 2:00p Room: Pearl

OpenLCB/NMRAnet DevKit Available

Model Railroad product vendors, developers and early adopters who are interested in the developing NMRAnet standards and developing NMRAnet products, may be interested in the OpenLCB/NMRAnet Developer and Early Adopter Kit.

The kit includes:

The DevKit comes with the following documentation:

  • The DevKit QuickStart guide.
  • The DevKit Tips describes the various connectors and interfacing options available.
  • The Understanding DevKit Ios describes the special Demo-Mode Events that these Ios come pre-configured with and how they can be reset back to normal Events mode.

The Dev Kit is available to interested parties for $US 50 (plus shipping) and you can apply by describing your interest and plans for it in an email to David Harris at It is expected that you will install the nodes onto a real layout, wire up a bunch of sensors and output devices to provide a typical environment for exercise the hardware and provide feedback on the NMRAnet Yahoo Group and/or the OpenLCB Yahoo Group.

As OpenLCB specifications are still being designed, these prototypes are under active development and new firmware updates may need to be loaded and tested periodically. Instructions are provided, but you need to be comfortable with doing these types of operations.

Other commercial products that are available include:

  • The RailstarsIo:duino, an Arduino clone with a AT90CAN128 and native CAN on-board.
  • Silicon Railways LEDuino, an Arduino-clone with a ATMEGA328 and MCP2515 CAN on-board.
  • Three TCH Technology nodes, including a CAN/USB adapter, 32-Consumer, 32-Producer, and 24-Consumer/16-Producer nodes.
  • RR-CirKits is working on a Control Point node.

First Final Draft Documents Available

At long last we have processed the first-of-many OpenLCB documents through to the point of Final Drafts. Once adopted they will form the basis of the new NMRAnet Standards and Technical Notes. These documents are now available here.

These have been a long time in the making as this whole process is new and is being worked out by volunteers who have demanding full-time jobs and other commitments and are spread across several time-zones. Now that we have the initial documents through the process, we hope to have the next set of OpenLCB documents processed through to NMRAnet Drafts stage much sooner.
