I have a 2000 Saturn SL1, which uses OBD-II. I got a program that will read the codes from my car to my laptop.
I have a cable that connects to the car's OBD connector, but the other end that's supposed to plug into my computer is an LPT1 (printer) port.
The only free OBD-II software that I've been able to find only seems to support COM1 ports, but not LPT1 ports.
Can I just use an LPT1 to COM1 adapter to connect it to my computer? Or do I need to go out and buy myself another cable?
Could it be a 25 pin serial connector? does it say RS232 on it? if so you need a 25 to 9 pin adapter. The instructions (or the website) should give more details about this.
Unfortunately though, it cannot input live data from the sensors.
You can't use that cable from that code reader. It was designed specifically for that unit and won't work with your software or your laptop to do what you want to do.
You will need to purchase an ELM compatible interface to work with the OBD software on you laptop. They come in either a serial (9 pin) or a USB version. You can Google ELM 327 to find a compatible device for your setup.
If you mean the top connector of the handheld device I donīt believe that you can connect that into a computer. This is probably some interface which only compatible with this particular device.
1. There is a separate USB cable in the background
2. The description states Custom PC Software is available for reports and update tool
3. The display is battery powered for off-vehicle review
OBDII is not a communications network which can connect directly to a computer without some kind of interface/protocol converter. Without the display device I would say the cable is useless and will not do anything for you.
