Greetings. We bought machine from title with heidenhain TNC 310 control. I am trying to connect it to pc. Problem is i dont have cable so i decided to make my own. DNC is Dsub25 pin female. On my end i have Dsub9. I was reading all kind of manuals where they show schematic from logic to adaptor to out of machine. But they all end up as 25 to 25 pin cable. I have spent hours and hours of soldering to try to find solution. And there is no solution for me i cant get any connection. So if anyone knows pinout from 25 to 9 Dsub connector i would be thankful for help.
