“If you connect your arduino directly to an RS232 signal you’ll destroy it - that’s what RS232 to TTL converters are for so you can connect TTL components to RS232 components without letting the smoke out…“
Ohh ok so even if I attach to rx I need to still use my rs232 to tll converter
Ok will do
The baud rates etc are sane on arduino as the sending device parity, stop bot etc
Great news finally I have it working I have been working on this on and off for months
So now the rs232 data outputs as expected connecting it rx and vis the rs323 to tll adaptor
Once again I thank all those helping me along the journey

Claude,
Good to know you finally got sorted.

It’s been a bloody long haul and a hurdle for me to move my project toward poc
Re obd2 I can see my wanting to build my own messages to be recognised by an existing display that accepts data may be a bigger challenge so may either go down path of creating own display using obd2/can shield and display shied.
Anyway happy to keep you updated with progress if you would like as i walk the path to a poc that can be present for evaluation for commercial product potential development
