I made the 2-transistor style cable a few days ago but haven't been able to locate a laptop with a serial connection and I'll be damned if I spend $40 for a serial-to-usb converter when I can build USB dedicated cheaper! KUDOS on the find! I will take pics and post the write up, giving you credit of course, if you don't mind. 1 to mount permanently and another to make a cable to be used universally. still an excellent price, IMO.Īlright Robert, I took the plunge and ordered 2 of the FT232R setups.

went from 8.80 to 10.80, free shipping in both.

looks like the little pads that seem like they're missing a component would be soldered together to cause 5V?Īnd the most current link for the one i bought before. not sure about the 3.3 to 5 volt setup, not really clear on it in the description. the way the listing is written, it may convert to RS232 specs, which is not the easy method as decribed before, but would work if using something to convert RS232 to TTL (MAX232, similar).

i'd like to do a 160 baud test, but i don't want to try and dig out the 85 IROC ECM.Īnother potential option. since it uses the FT232RL, it should be a quality, long-lasting unit.

attach a male OBD1 connector (for $15 plus shipping from, or i potentially have an overseas supplier that has a cable that can be used after some tweaking for a little under $9 shipped) and you have a fully functional and professional enough looking cable.Īnyways, tested at 8192 and it works flawlessly. put it in a radioshack project box for like $3(since this came with it's own USB cable) and you're out the door with a USB ALDL cable for just under $12. Now, assuming you can get ahold of a male ALDL connector or just use the bare pins for whatever reason, you'll have 2 or 4 quick solder joints to make and then you're done. then soldering into the solder cups of a DB9 connector? also a pain. ever built a MAX232 on proto boards? they're a pain. So anyways, before this i was using Parallax 28030 units, which are serial->USB adapters, so i converted the 8192 stuff(basically TTL?) to serial using a MAX232 circuit, then converted serial to USB using the Parallax 28030. also passes the tunerpro "test for cable" when unplugged from the car, not something i'm used to with my current cable. just went and tested it on the MC, works great. :homer:Īnd when it comes to homebrew hardware, simple is always good.
