I watched as others gave up on the Dyna control and "upgraded" to PC control over the frustration of not being able to load programs.
I tried some demo DNC software and had limited success (Multi-DNC trial version worked for me).
I tried Hyperterminal. I tried a hundred things.
I use NCLink from OneCNC & it's FREE. CAD CAM CNC software solutions by OneCNC CAD/CAM
It WORKS. You need to do some things with your program to make the transition beyond 900 lines. There's a thread here where I describe the setup for my DM2800, although not guarenteed to work on your machine might get you close. http://www.cnczone.com/forums/bencht...nications.html (Dyna Myte 2800 RS232 communications)
