NCE Bus

This page is the umbrella page for projects involved with interacting with the NCE Bus.

----------------

Introduction

The NCE bus is used to combine several NCE devices. For example, a controller plus individual controllers.  Shown as a "Host Controller" and "Slave Controllers" in the following diagram. The Slave Controllers are also known as CABs or Throttles

The photo shows a RS485 card mounted on an Arduino UNO. The wires to the left are Black Ground, Red B- and Green A+. Yellow is not connected. Some documentation on the www suggest that the Green and Red should be reversed.

The Projects

 The following pages build up a class/library NCE_Bus_Probe.

1. NCE_Bus_Probe1 will capture the bus activity as a string of bytes. Any messages will be decoded but not used at this point.

2. NCE_Bus_Probe2 will illustrate how to extract the messages. These will be displayed on the monitor.

3. NCE_Bus_Probe3 will illustrate the start up and handshake responses from the slave controller.
