• Processes or information communicated through the serial port are not operating properly.
• The CNC is unable to download files through the serial port.

To test serial communications:
1. On the Machine Interface screen, choose the serial port you want to test.
2. On the CNC, plug the serial test hardware into the port you selected.
3. Choose Test on the serial test screen. A message informs you if the test is successful.
If the test fails, contact your table manufacturer to replace the utility and serial isolation board (141307).
