APPLICATION NOTE 4599
Use a DS3900 to Evaluate IC-Compatible Devices for Successful
Bidirectional Communication
By: Jason Andrews


Abstract: This application note explains the design considerations and hardware requirements for developing a hardware
solution to establish IC-compatible communications using a DS3900.


Introduction

The DS3900 is used to evaluate IC-compatible components, and it provides fast, bidirectional communication with 2-wire
devices using a PC's serial port. Figure 1 shows the recommended configuration for establishin
