I am able to connect to my X3 and see data through esys. Cable is working perfectly. I will now study the procedure in details before going into experimentation.
The most critical element so far was getting the cable
. Being an electronics engineer, making right cable was not a problem for me but its not every ones cup of tea. Tiny wires with good connection and no chance of making a short any where needs skill. I think I can support others if they want to have the reliable cables.
