Hello students, to check the serial communication between the data accusation equipment and the computer, the techniques can improve the several troubleshooting steps to identify and resolve the issues.
00:14
So here are some common steps to follow.
00:17
As the first step, we need to check the physical connection.
00:32
Ensure that the data accusation equipment is properly connected to the computer serial port.
00:39
Verify that the connectors are securely plugged in and that there is no physical damage to the cables.
00:47
The second is to check the serial port setting.
01:01
As verified that the serial port setting on the both computers and the data accusation equipment are properly configured and match each other.
01:14
The critical parameters to check include the as the baud rate and the data bits, stock bits and the partial setting.
01:22
The third step we include test with the different equipment.
01:42
Test the serial port with the different data accusation equipment or the different computers to see if the issues are precise.
01:51
So this can help to determine if the problem is with the equipment or the computer serial port.
01:59
The next step is to use the loopback test.
02:11
As it performs a loopback test by connecting the transmit that is the dx and the receiving the pins that is rx of the serial ports with the shorter jumper wire, sending the data from the computer should result in receiving the same data back.
02:30
So this test helps to verify the functionality of the serial port itself.
02:34
The next step we include check for the buffer overflow.
02:49
As if the data accusation equipment is transmitting the faster than the computer can process, it may lead to the buffer overflow causing the data loss.
03:01
Check the data accusation equipment's data output rate and ensure that the computer serial port can handle the incoming data...
