An increasing number of new Laptops no longer have a serial port fitted in favour of more USB ports. In such cases it is possible to use this USB to RS232 adaptor which converts the USB to a Serial port.
Please beware that this lead supersedes AC002 and unlike that lead, this new one connects directly to the Vehicle Server.

You can download the required drivers from the downloads section here, under Public Downloads -> Faultmate MSV2.
