Acknowledge the message at the operator panel by pressing the 'RECALL' or acknowledgment softkey to clear the informational display.

Verify the RS232C interface parameters match your connected device (baud rate, parity, data bits, stop bits) in Settings > Interfaces > RS232C configuration menu.

If using the interface for data transfer, proceed with your intended operation (program upload/download, DNC operation, etc.).

Document the occurrence if this message appears unexpectedly during operation, as it may indicate an interface reset or communication interruption that has recovered.

Unexpected interface resets during active data transfer may cause incomplete file transfers or data corruption.

Check the physical RS232C cable connection between the control and external device (PC, laptop, or peripheral) to ensure proper seating of the connector.

Verify the external device communication software is properly configured and active with matching communication parameters.

Test communication by performing a simple operation such as requesting a directory listing or sending a small test file to confirm bidirectional communication.

Clear the message and proceed with your data transfer or DNC operation as planned.

Ensure no active machining operations are running when performing large data transfers to avoid processor load affecting cycle time.

Review recent changes made to communication settings in Commissioning > Machine Data or Settings > Interfaces to identify what triggered the interface reset.

Changing communication parameters without documenting original settings may prevent reconnection to previously configured devices.

Verify the new communication parameters are correctly saved and match the requirements of connected external devices.

Test interface functionality with connected devices to ensure communication works properly with the new configuration.

Document the configuration changes in the machine logbook and update any communication setup documentation for future reference.
