Hi
I've tried everything to solve my problem read everything but i can't solve it.

I use rs232 to usb converter to connect my machine and I checked everything that I read about it.

In Windnc my setup is ok but when I click the folders it says transmission error but my parameters are correct and my cable I just bought it.

Thank you for your time and I hope someone know the solution

Try a computer with a real serial port, I seen so many times where these USB to serial adaptors just don't work

Did you check if the converter is working properly? Do you get the echo in the terminal program when you short Rx and Tx together?

I have seen the power supply to the serial interface fail.om them before.
This made both RS232 and RS422 ports fail.
You could could confirm this by testing the plugs on the cnc. With either a multi meter or with a led serial indicator.

If you trust the cnc is ok and you are confident the problem is in the pc, you should check the com Number.
Normally usb adaptors assume COM8 or some other above COM4..... try to rename it to other number under COM4.

Why you bought new cable?
Are you sure you have correct pin out?
Different FAGOR models have different pin out, specially the older ones. Which one is the model you have?
