In Tunerpro try testing using Tools - Preferences - Click the Data Acq.Emulation tab at the top of the pop up box - then click "Configure Plug In Component" - Then "Test For Valid Interface Using...

Glad to hear you got it working. Weird that you had to roll back the driver to make it work. I ship the latest drivers along with my cables and they are FT232RL based. FTDI has it's drivers...

Pins 4 & 5 are ground. Pin 9 is data. No 10K resistor is needed. Yes pin 16 is 12v if needed.

You will only be able to scan your VY Commodore. Use TunerPro RT and the .adx definition for the...

If you can't set the baud rate to 8192, don't plan on it working.

It is illegal to sell pirated clone chips or cables made with pirated clone chips in the US. You could end up in criminal or civil trouble.

From the negative attitude I got from FTDI when I...

Not me btw.

The diagrams for making a DSM cable start with a Rs232 serial port board and then they add the diode and resistors. Actual RS232 ports operate at a + or - 15v. The cable you show is for a TTL level...

My bench 7747 running ASDU connects right up without the 10K in place.

If your cable fails TunerPro RT's self test (test with the cable plugged into the laptop but not plugged into the vehicle)...

Yes it should

Start with not connecting VCC to 5v. Normally that isn't needed, but you are using a different board so idk. If you have no lights at all when you are plugged into the USB only then do it, but if...

Yes 1227747 = 160 baud

Your best bet is here - http://aldlcable.com/sc/details.asp?item=daewoo

That way you know you have all the conductors that are needed. A lot of the OBD1 junk out there don't have wires on all the...

It seems odd that they would use RS232 voltages and then tie them together in one wire, however that is quite similar to what GM did. It would be interesting to see if a standard FT232RL works,...

You still need to add the ALDL connector itself and a housing if you wish to compare the price to a purchased cable.

Otherwise you might as well compare the price of the FT232RL chip to the cable....

Well then for sure get the one that has the clear 3v-5v jumper on it. It should work.

I to also sell on ebay - Seller name RedDevilRiver also Phonedawgz

btw, yes it costs more on ebay - to pay...

Are you talking about the one that I sell?

It is ready to go, plug and play. It does include the A-B resistor if needed. You can order it with either the 12...

I don't see the jumper either, I'm just going by the text.

The FT232RL works so it looks good, however the only way to find out if that board in particular works is to try it. The signaling needs to be 5v TTL, not 3.3. It isn't clear if the jumper selects...

You have to send a series of rotating/reversing electrical signals to move a stepper motor (IAC). You can't just jumper power to it.

I do sell USB to ALDL cables for less.

http://reddevilriver.com/aldl.html

Yes it works out of the box.

Yes it is based on the FT232RL chip

Yes it works for both Pin E 160 Baud and Pin M...

If you shorted A- B, the ses light will blink out the SES codes
If you had the 10K resistor between A and B - then the flashing light will tell you if the ECM is in a rich or lean condition. Note...

If you are looking at a 160 baud - one directional cable, and you want to keep the 3.3v input - you should be able to do it with just two resistors to divide the voltage. A single resistor inline...

Earlier OBD1 vehicles need a 10K resistor between pins A and B to start the data flow.

Later OBD1 use bi-directional data flow on pin M and don't require it. Having the 10K resistor between pins...

The PL2303HX chip is 3.3 to 1.8 on it's TTL output only, so there is no chance of it working for an ALDL cable.

I have tried with the 5v version of the PL2303 (PL2303H) but have not had success....

USB to ALDL 160 Baud Pin E or 8192 Baud Pin M cable for $55 shipped -

It does use the FT232RL chip

By the time you do $10-15 for the FT232RT USB,...
