CNC Setups: FADAL

In order for your FADAL CNC to communicate correctly with your computer, make sure that:

  1. Computer has a serial port (RS-232) available. Identify whether the port is COM1 or COM2.
  2. RS-232 cable must be appropriately wired (see wiring diagram bellow)
  3. Parameters settings are the same in both computer and FADAL VMC:

Use cable with following connections

Note: When shielded cables are used, pin #1 at CNC needs to be connected to the not-insulated wire of the cable (shield).  Do NOT connect pin #1 at computer side.

OPTIONAL - Hardware Handshake

There are two types of handshaking:

  1. Hardware:  By removing voltage from pin #6 (DSR), the CNC pauses the transmission until the voltage is established.
  2. Software:  (XON/XOFF) protocol:
    DC1 - Ready on (ASCII 17)
    DC2 - Punch on (ASCII 18)
    DC3 - Ready off (ASCII 19)
    DC4 - Punch off (ASCII 20)

 

Receive data / programs at the VMC

  1. [VMC]  At the ENTER NEXT COMMAND prompt, enter the command CD,# and press ENTER to switch to "terminal mode".  (# represents the baud rate code number)
  2. [VMC]  Enter the command TA,1 and press ENTER.
  3. [Computer]  Perform the software procedures to transmit the file to the VMC.
    File sent to the VMC should start and end with the percent (%) symbol.
  4. [VMC]  After receiving the file, press the Manual button to return to the "command mode."

Example:  If you want to set the baud rate at 2400 baud and ready your VMC to receive a program, at the ENTER NEXT COMMAND prompt, type these two lines:
    CD,6 ENTER
    TA,1 ENTER

 

Send data / programs from the VMC

  1. [VMC]  At the ENTER NEXT COMMAND prompt, enter the command CD,# and press ENTER to switch to "terminal mode".  (# represents the baud rate code number)
  2. [Computer]  Prepare the computer to receive a file.
  3. [VMC]  Enter the command PU,2 and press ENTER.
  4. [VMC]  After the computer received the file, press the Manual button to return to the "command mode."

Example:  If you want to set the baud rate at 2400 baud and send a program to your computer, at the ENTER NEXT COMMAND prompt, type these two lines:
    CD,6 ENTER
    PU,2 ENTER
