    If you have the PCB, you can find a way to read the hex codes embedded inside. If the code is protected, I guess the only way is to do reverse engineering and write your own code that would make the circuit work as intended just like what Okada is doing.

    Dont think this is a simple piece of job even for the experienced people here; me not included. I am just a hobbist like you...

    Thank you absf for your replay..... Its code is protected.. I try to read. So I now searching internet for that.. I think I can find one for the same, But I need more time...

    I previously say that, "you can got anything from internet, but you can't get your Dad and Mom. But I now say, extend your time for searching extra five minute, you can also get them.."

    I really Belive my words, I have many reason....many reson...

    anyway thank you for your kind attenssion in my post and help........
