Hi Michael
We are now able to reliably connect to a new unit and a 'previously used' unit.
I'm accepting that one unit I have done a lot of testing with now seems to be faulty.
I'm happy to now call this issue 'closed'.
Thank you for your assistance and patience.
We got there eventually :)

Hello, again..

5v signal from adaptor TX line converted to 12v
snap one shows 12v level pulses on the line when PCAN-LIN unit NOT connected

This works OK, checked with scope, however when the PCAN-LIN box is connected it clamps the voltage at it's pins to 5v, must be some ...

Hello,

So we now know speed is factually at 38400 but still unable to connect with a simple USB/RS232 interface, it is an FTDI, tried both inverted and non-inverted RX,TX ...

Thanks for your reply, however I'm still struggling.

Hi,

please use a standard USB2Serial (FTDI) with -12/12V Levels for RS232. 5V TTL Levels are not supported by PCAN-LIN

Please also use a 1:1 cable without crossing, or simply connect the PCAN-LIN directly to the USB2Serial adapter ...
