RS232 Explanation

When connecting RS232 to a UTOR or other device, please note that the IN and OUT of RS232 are cross-connected, meaning IN connects to OUT and OUT connects to IN; otherwise, communication will not be possible.
When using RS232 communication, ensure that the ground wire of the tool board and the upper computer are connected together; otherwise, communication will not be possible.
