RS232 port
« on: February 27, 2007, 10:37:24 AM »
I have just bought new software for my laptop, it's for diagnostics on cars. The software has been configured to use a rs232 (db9) socket on the laptop to conect to the OBD2 on the car, the only thing i have on my laptop is USB's and the 25pin printer port. Is there a way around this?
many thanks.

Regarding the software you bought:    
Does it have a webpage?    Got any links you can post here?

Is a shareware version downloadable?


...just on the outside chance that somebody might spot something in the config/docs/webpages  about how to get your software to point at  a USB port instead of a com port.

    If the software can be configured to use LPT1, you can purchase a parallell to serial converter. Windows has a built in feature that works for printers but I don't know if it would work for your software. It allows output to LPT1 to be redirected to a USB port.
    If you don't stand for something, you'll fall for anything.

    Yes these are some of them:

    Check out:
    http://www.scantool.net/products/index.php?cPath=5&osCsid=46f2e0ac3abe53f490ba1298b4ba4146
    There are several cables on that page.

    See:

    The USB to Serial converter allows ElmScan interfaces to be used with laptops that do not have a serial port. This product is based on the Prolific Technology PL-2303 USB to serial converter chip. For best results, be sure to download the latest drivers from the Prolific Technology website.

    I don't think they'd be selling the cable if it was not possible to use it with their software.    :)
    I have not read every word there -  maybe I'm mistaken.

    This looks to be commercial software only.   I did see a place there where you can email them.    If this is the software you bought,  if it were me I'd expect a reply to an email inquiry.  
    Have you emailed them and asked?


    Btw,  the ScanTool software looks to be free.    Thank you for mentioning it.    I sort of wanted to find free OBD software, and hadn't put much effort into looking around.
    If and when you get it working,  would you mind posting again to let us know how it works, if you like it, etc., etc. ?

    If you learn of any other OBD free software out there,  let us know too.    Thanks.
