Right, those two resistors aren't needed, but I'd connect pin 10 to ground.weezlebub wrote:Unfortunately i am still having the same issue after building max232 cable.
I use the schematic http://www.techedge.com.au/vehicle/aldl8192/8192hw.htm.
I left out resistors r2 and r3 cause my vy series 1 v6 doesn't have those pins on the car. Is that right?
Wondering if i got wrong setting somewhere
Ok thanks its not an old laptop and it has a smsc lpc47n237 io controller in the dock for the com port . I think that my problem thenantus wrote:If its old enough that its a genuine 16550 chip behind it then it will. If its a built in usb to serial then itll be no different to needing a compatible usb adapter.
I ordered a cheap FT232RL USB to TTL on ebay. I read you just tie the RX and TX and works at 8192bps. Probably not genuine though so not sure but read on here someone who had one working at 8192bps. I'm not really interested in tuning just want to be able to check codes.antus wrote:Yep i'd think so. If you really want to use your own cable you could try getting a genuine FTDI usb to serial as they are known to work with stock settings out of the box.
Non-genuine = wasting your time. If the converter was cheaper than a genuine chip, then it's too good to be true.weezlebub wrote:I ordered a cheap FT232RL USB to TTL on ebay.
