GReddy e-Manage Support Tool

Page history last edited by wilbo666 3 months ago


 

Introduction

This page outlines how to construct a GReddy e-Manage (Blue) Support Tool cable.

 

This page also links to the required PC software and wiring diagrams.

GReddy e-Manage (Blue) Support Tool Cable

The GReddy e-Manage (Blue) has a USB connector on it, however it does not support USB communications, this can catch quite a number of people out when they go to connect their GReddy e-Manage (Blue) unit to their PC for tunning.

 

GReddy charge quite a significant amount of money for their 'Support Tool', which effectively simply takes the  TTL voltage level (0V to 5V) serial data from the e-Manage unit and converts it to standard PC serial port RS232 voltage serial data for the PC.

 

It isn't particularly hard to construct a Support Tool Cable yourself and the following information should allow you to construct your own GReddy e-Manage (Blue) Support Tool Cable.  This design fits the PCB and required components inside a conventional plastic DB9 housing.

 

As a further note I have also successfully used this design with USB to RS232 serial converters with laptops that are not equipped with a serial port from factory.
