Nearly ready to install bodies on my 205, loom is built up, got a base map, DTASWIN installed on desktop PC (haven't got hold of a laptop yet)
USB to serial adapter purchased, up to date Drivers installed from Prolific website.
ECU powered up with a battery reading 12.6v, fuel pump relay primes fine.
I get this error:
I have checked which comms port the USB is connected to, DTASWIN is pointing to the correct port.
I am connecting through a POT box I have made myself which saves buying or making a specific lead, would be so much simpler if they used an USB connection...
I have confirmed pinouts to be correct through the box

Re: comms issues via usb
try a different com port, some times windows applications reserve one!
Re: comms issues via usb
have done, there are 6 ports and none will do anything but return this error.
Re: comms issues via usb
have you tryed rebooting?
Re: comms issues via usb
hang on is that a monitor lead? you might have problems with that, sometimes they gang a load of pins to the screen for a ground connection!
Re: comms issues via usb
bother!
I have no idea what it is specifically but its quite likely, I know the 5 main pins buzz through correctly, I'll check the rest.

Re: comms issues via usb
I think you nailed it, just tried to buzz a few pins through, damn tricky as they're so small and I only have two hands! but as you suggested, the main earth on pin 5 pulls several others to earth as well which are the knobs, though none of these are connected to the 9 pin at all, I guess it would be confusing the hell out of the ecu.
Re: comms issues via usb
yea the outher day i made a lead like this for a tricky install, you only need pins 1 - 12 so moniter cable will do it, but i put new plugs on to get rid of the linked up pins.

Re: comms issues via usb
If buying cables to butcher, always best buying extension cables. That way they are usually just straight through, pin to pin
Re: comms issues via usb
Right, got 2 plugs from maplin and made a straight through 9 to 15 and still no luck.
USB set to com1, FIFO buffers set to min (Suggested by Sandy Brown), also tried with them off.
with ecu off, get the usual ecu off/not connected error,
power ecu up it primes FP relay, but I get comms port already in use error.
