  First, check the RS232C cable connection, ensuring it's properly connected to the correct serial port. Next, verify that no other display is connected with a duplicate ID, as this can cause data collision. Finally, confirm that the display ID is within the range of 0 to 99 by changing the ID in the Display menu if necessary.
