Communication with a Serial ECU via USB - Serial Adaptor

Postby HaltechScott » Mon Sep 20, 2010 2:32 pm

When using Windows based Haltech software (HalWin) you can use a USB adaptor if there is no Serial port on your laptop.
Before using a USB to serial adaptor you must install the manufacturers supplied drivers onto your Laptop. After the USB adaptor is set up you need to find which Com Port number the Operating System has allocated before using Halwin. Before you go Online you need to configure select the correct com number under 'Setup/Program Setup' edit Com port details.

A warning for some brands of USB to Serial adaptors, some of these have poor response and no provision for any setup changes which can give you a staggered screen update and a slow response. One of most typical problems
with this behavior is Halwin will ask you for a 'Password' because of the corrupted communications between the pc and the ECU.

Installing USB to Serial Communications Port Adaptor:

Install USB to serial adaptor device driver from the product installation CDROM provided with the adaptor. Once the driver has been installed you will have to make sure the Haltech ECU software (Halwin or HalwinX) is setup to read from the same COM Port that the adaptor has installed itself as.

The following guide will help you through the process, with the USB to serial adaptor plugged into a USB port.

Using Windows XP
1 - Select MY COMPUTER, under the Start Menu.
2 - Select SYSTEM icon.
3 - Select HARDWARE tab.
4 - Select DEVICE MANAGER button.
5 - Open PORTS(COM&LPT), and select the USB-to-Serial Comm Port. 6 - Select PORT SETTINGS tab. 7 - Click ADVANCED button. 8 - Under Com Port Number, select Com1, as long as not already in use (any com port 1-4 can be used, just be sure to select the same com port when setting up the Halwin software). 9 - Click OK.

Using HalwinX V1.26:
Open HalwinX 1.26.
Under SETUP on task bar, select COM PORT SET UP.
Under Port, Select COM1 (or whatever you have selected in your device manager in step. Click Apply and then OK Close down HalwinX and restart the software, you should now be able to communicate and go online with your Haltech ECU.

Select EDIT COM PORT DETAILS tab.
Under PORT, Select COM1 (or whatever you have selected in your device manager in step) Click Apply and then OK Close down Halwin and restart the software, you should now be able to communicate and go online with your Haltech ECU.
