INTRODUCTION

The DS2705 evaluation kit (EV kit) makes performance evaluation, software development, and prototyping with the

DS2705 SHA-1 Authentication Master easy. The evaluation board interfaces to a PC through a DS9123O USB

Adapter and RJ-11 cable connection as well as to a DS2703 or DS2704 EV kit evaluation board. The provided CD

ROM contains all related data sheets along with the evaluation software, which can be run under any Windows

operating system that supports USB operation.

The DS2705 EV kit evaluation software allows the user to completely program and configure the DS2705. It also

provides limited programmability of a DS2703 or DS2704.

The evaluation board circuit is designed to provide the DS2705 with a stable environment to perform a SHA-1

Authentication with a DS2703 or DS2704 and display a Pass/Fail on the result. Kit demonstration boards will vary

as they are improved upon over time. For information on the demonstration board circuits refer to our website at

www.maxim-ic.com.

SETUP AND INSTALLATION

BOARD CONNECTIONS

Connections to the demonstration boards are best made either by soldering directly to the pads or by using cables

with mini-grabber clips. The DS2705 EV Kit has 2 RJ-11 Jacks labeled “ MASTER” and “SLAVE ” since the

DS2705 can function as both a Master and a Slave.
