1. Introduction

1.1. General remarks

First of all, we would like to congratulate you to the purchase of a high qualityDEDITEC product.

Our products are being developed by our engineers according to qualityrequirements of high standard. Already during design and development we takecare that our products have -besides quality- a long availability and an optimalflexibility.

Modular design

The modular design of our products reduces the time and the cost of development.Therefor we can offer you high quality products at a competitive price.

Availability

Because of the modular design of our products, we have to redesign only a moduleinstead of the whole product, in case a specific component is no longer available.

1.2. Customer satisfaction

Our philosophy: a content customer will come again. Therefor customersatisfaction is in first place for us.

If by any chance, you are not content with the performance of our product, pleasecontact us by phone or mail immediately.

We take care of the problem.

1.3. Customer response

Our best products are co-developments together with our customers. Therefor weare thankful for comments and suggestions.

3.1. Application examples

3.1.1. Programming under ispVM System

Start "ispVM System" as follows:

Start -> Programme -> Lattice Semiconductor -> ispVM System

Software |Seite 11

3.1.1.1. IspVM System - Configuration

To use the "USB-JTAG" in full volume, you have to make some preferences in theoptions. Start "Cable and I/O Port Setup" via "Options -> Cable and I/O PortSetup..."

Software |Seite 12

At first, connect the "USB-JTAG" to the PC. By pushing the "Auto Detect"button, the port and cable connection will be searched automatically. The foundconfiguration is shown ongoing automatically. The configuration should look asfollows:
