6. After the installation is complete, please confirm that “USB Serial Port (COMx)” appears in the “Port (COM and LPT)” expansion item in the “Start\Settings\Control Panel\System\Hardware\Device Manager” menu of Windows. This COMx is the COM port number used by the USB programming cable. In the future, the COM port will appear whenever you insert the programming cable. You only need to select the COM port in the application software such as programming software or communication software.

Mitsubishi usb sc09 fx use notes:
1. If the USB programming cable plugged into the computer is not detected when the computer is turned on (the COM port corresponding to the cable does not appear in the Windows device manager) or other abnormal conditions occur, please re-plug the USB plug once.
2, USB to UART is a plug-and-play USB device, it can not be disconnected during data transmission (disconnect means to pull out the USB cable from the USB socket), that is, must be closed in the application After the serial port, you can unplug the cable from the USB socket.
3. Sometimes the USB communication error occurs when the Windows system is faulty or the USB cable is plugged in during communication. At this time, it may be necessary to restart the computer and the PLC.
4. Generally speaking, it is best to insert the USB cable into the USB socket first. After the computer detects the COM port, insert the other end of the programming cable into the PLC communication port. Because some PLCs work in the master station mode, the communication port is always in the communication port. Sending data to me continuously, such as plugging the cable into the port of the PLC first will reduce the speed at which the computer correctly recognizes the COM port.
