Chapter 1: Starting out

Introduction

The Ellisys USB Explorer 260 is a sophisticated protocol test system for USB traffic

monitoring, driver and software stack debugging, protocol compliance verification and

performance analysis. The EX260 can reduce your R&D development time by finding

issues early and debugging more efficiently, and can improve quality and reliability by

verifying compliance to the specifications.

The Ellisys USB Explorer 260 is available in three configurations:

The Ellisys USB Explorer 260 Analyzer includes Ellisys' analysis features with

real-time monitoring, hard-disk data streaming, class decoding, traffic statistics,

and triggering and filtering.

The Ellisys USB Explorer 260 Generator supplements protocol analysis by

emulating USB devices and hosts, and by testing corner cases and recovery

mechanisms. Reproducible traffic, timing and error scenarios can be created

with a scripting environment. Captured traffic can be replayed to test a

particular situation. The Generator supports Inline Error Injection feature to

insert programmed errors between a host and device to determine the impact of

transmission errors under rare conditions.

The Ellisys USB Explorer 260 Duo is a flexible bundle of two full-featured

units that can be used as one analyzer and one generator, two analyzers or two

generators depending on your testing requirements. More convenient than

having both functions on the same unit, this allows you to better share your test

equipment among your R&D team.

Common terms

The following terms are used throughout this manual:

Analysis software The analysis software enables users to record data sent

by the analyzer and subsequently displays them in a

simple, easy-to-follow format.

Generator software The generator software enables users to write, run and

debug generator scripts.

Device Under Test A USB device that is going to be analyzed with the

analyzer is called a device under test in this document.

Host Under Test The device under test will be plugged into the Host Under

Test through analyzer's Link Under Test connectors. The

Host Under Test can be any host including a PC, an

embedded computer, a PDA or even a custom piece of

equipment acting like a USB host.

Chapter 2: Connecting the unit as protocol analyzer

Introduction

The Ellisys USB Explorer 260 Analyzer is a non-intrusive USB protocol analyzer that can

connect on any link between any host controller and device.

InterChip USB is supported with an optional analysis probe that connects directly

on the USB link between the embedded host and device on a PCB board. Please

contact [email protected] for more information about this option.

The EX260 Analyzer sends data using a High-speed USB 2.0 connection. Although the

unit can download analyzed data on a Full-speed USB 1.1 connection, it is strongly

recommended that you connect it using a High-speed USB 2.0 port to obtain optimal

performance. If you experience any trouble with your analyzer, please ensure it is

connected on a High-speed USB 2.0 enabled host controller before contacting our

technical support.

The Power LED of the front panel is illuminated in green when the unit is

connected on a High-speed USB 2.0 link, and in red when connected on a Full-

speed USB 1.1 link.

Connecting the Analyzer to a computer

Configuration with two computers: recommended configuration

The use of two computers is the recommended configuration (see Figure 1). The Host

Under Test is ascribed to the Device Under Test, and the analysis computer handles

downloads and analyses data coming from the analyzer.

Figure 1 - Configuration with two separate computers

Version 1.0.0 November 22, 2007

Configuration with only one computer

It is possible to use just one computer for both testing and analysis (see Figure 2), but

this may affect the performances of the real-time data monitor and download. You

must, however, ensure that two or more host controllers are available on the

computer. If there is only one host controller on your computer, a CardBus or PCI

extension card can be purchased to add a second host controller to an existing

computer. Please refer to the chapter on Troubleshooting to determine if your computer

has two host controllers. The following diagram shows how to use the analyzer with

only one computer.

Connecting a device under test for analysis

Connecting only one Device Under Test

The most straightforward configuration involves only one device to be analyzed.

Figure 3 shows how to properly connect the device under test.

To prevent problems which could arise from your cables' length, please follow the

following instructions:

-The blue cable must be no longer than 5 meters.

-The total length of the red and purple cables must not exceed 3 meters. A

greater length could result in an abnormally high error rate on the bus being

analyzed.
