Chipi-X Cable

Chipi-X is a USB to full-handshake RS232 cable with a male DB9 connector. This cable is

available with or without an enclosure.

1

Introduction

The Chipi-X cable is a USB to RS232 level full-handshake UART cable. Chipi-X utilises FTDI’s

FT231XS USB to full-handshake UART IC and FT3243S RS232 transceiver IC. A male DB9 (aka

DE9) connector provides the connectivity for RS232 communications and a USB-A plug tethered

by a 10cm cable to the PCB provides connectivity for USB communications.

All components used are Pb-free (RoHS compliant).

1.1

Features



Entire USB protocol handled on the

FT231XS chip



FTDI’s royalty-free VCP and D2XX drivers

eliminate the requirement for USB driver

development in most cases
