Has anyone tried to download the demo Heidenhain it530 software for your pc. I tryed to download it but i'm not getting something right. The control panel on the machine has keys that a pc keyboard does not have. Any info will be greatly appreciated.Thanks!

If you extracted the files from the large .zip file look for Pgmplatz_tast_en.pdf
That is a printable Acrobat PDF file of the PC keyboard overlay. I've used the 530 emulator and it works great!
