1. Introduction

This document describes a system that has two QNX computers providing data to one Windows computer running an InTouch application. Cascade Connect provides the connection between the QNX and Windows computers. Each QNX computer is running a Cascade DataHub and it is assumed that all QNX data that we want to send to InTouch is duplicated on each datahub. This means that any QNX device drivers in the system will need to be configured to send data to both QNX computers so that both Cascade DataHub will have a mirror image of the current data set.
