Mazatrol 640M

[hense]

I am trying to transfer program from PC to Mazatrol 640. It works fine from machine to PC and when I transfer PC to machine, first 6 lines of the program is missing. I use ISO program and TAPE option to do the data transfer. I use a standard DNC software and it was working fine at other customer places with same controller. I do not want to use CMT. Can anybody help me.

Could be a few things... wrong baud rate.... baud rate too fast for length of cabe (try a slower baud) DNC start trigger not set up properly (on the PC side)...

Sounds like the DNC is sending before the control is ready. Are you starting the CNC receive first then sending from the DNC?
