End-Of-Line Testing & Provisioning

Fix Inconsistent Serial Port Assignments with USBHub3+

The Problem: Inconsistent Serial Port Assignment for multiple devices

A recurring issue when working with multiple USB-to-serial connections is that the operating system does not consistently assign port names. This is especially painful for end-of-line (EOL) functional test customers who are connecting multiple Devices Under Test (DUTs) at once, since it is important to know which DUT is passing or failing. 

Case Study: End-Of-Line Test and Provisioning

Introduction

This case study presents how an automotive supplier was able to automate firmware and OS provisioning and End-of-Line (EOL) functional final assembly testing using Acroname industrial USB hubs and switches and their USB Host switching features.  This automation resulted in reduced cycle times, less manual intervention and fewer errors while supporting a mix of software versions on the same production line.
