ALDL Interface
Posted: Thu Jul 04, 2019 7:44 pm
Hey guys,
I've got a ALDL USB interface I purchased from here years ago. I haven't used it for ages but thought I would pull it out to do some playing around with a VY PCM on the bench.
As soon as I plug it in, its recognised in windows and all drivers installed etc BUT when I hit connect hardware in tunerpro it says hardware not found.
I've got a status LED connected to the ALDL line on my bench setup and noticed it holds the ALDL data line low permanently when connected, regardless of being connected to PC or not (SO no other modules can communicate on ALDL with it connected).
In device manager it shows as an FTDI device with driver version 2.12.28.0
I pulled the case off and on the PCB it has "MPR" "delcohacking.net" "rev 1.1"
Its been stored well and I don't believe its been broken or dropped. There no sing of physical damage.
I have noticed C6 on the PCB is lifted and disconnected at one end only, but this looks intentional (the other side is still soldered to the PCB fine)
I remember something about counterfeit FTDI chips, but I wouldn't of thought that would hold the ALDL line low if it had been bricked by the latest FTDI drivers, and I know it would almost certainly be a genuine FTDI chip anyway.
Whats the potential problems?
I have the 2 earths, ALDL and battery voltage connected to the diagnostic port on my bench
Thanks
