Hello,

We have this machine in house but have no machine constants list. I'm presently trying to hook up a Shop Floor Automations unit (model is the 'Portable USB Connect') to the control via RS232.
I managed to download programs from the CNC to the USB Connect.
But it will not upload from the USB Connect to the CNC.

I don't know which constants to alter in order to upload from the portable unit

All I know is the machine constants numbers related to file transferring on a B3T control run from N770 to N777.
This machine has the older B2T control and the machine constants run from N1 to N300 only

Thanks in advance !
