The $250 you're spending isn't just for the cable; it's also for the license. The cable contains their own special electronics that allows the software to recognize that you bought a Ross-Tech license. They used to structure their licensing procedure like most software; you had a license code to unlock the software while the cable was nothing special. I vastly prefer the Cable/Dongle setup they have now since you can install the software on any computer you want and just plug the cable in and go. I hate keeping track of software licenses (like the Bentley manuals) and it makes switching/upgrading computers a pain.quipstad said:Is there a cheaper alternative for a $250 cable? Can I make my own?
I'm not tricking my way around the license. You can buy the license from their site for $99. If I do that and use my own interface, I still save $150 minus the cost of my interface. I was just wondering if anyone had any luck with interfaces other than the one included in the kit. When I said I have the software already, I didn't say it was registered. I'll still need a license to do anything other than test my cable. But saving over a hundred bucks is well worth a little hassle if it works. Hundred bucks goes a long way when you're broke.SeththeRuthless said:I don't much respect people who try to trick their way around the licensing system. Ross-Tech employees have to feed their families too.
'cos people are mugs and big companies take the piss because normal people don't realise that you can do things cheaper.quipstad said:Sorry for the double-post, but I guess I don't understand why it's so expensive.

Yes, you need to convert voltages from 12V to 5V in the case of RS-232. In the case of USB you need to convert speed and protocol as well.checkerj said:Actually, I'm probably being a little too simplistic on my pinout approach. Based on this photo, it looks like there could be some additional logic required to make your own cable:
Full offence intended, but that's stupid.Curious Chris said:So you want to build your own cable and save money. This I understand. So are you going to spend years to develop the software to do the diagnostics? Uwe spent a long time developing the software and what you are paying for is R&D. While Uwe was developing the software he was being paid nothing. He then produces a great piece of software and the only way he can recoup the money is by selling you a license for his software. You are paying for a license not a cable.
I think if you want to build your own cable and want to complain, you should develop the software yourself too.
