Key specifications

How to use

Connect the USB-C end to a host device with a compatible USB-C port and attach the DB9 connector to the RS-232 port of the target equipment. Ensure the host recognizes the serial interface; install drivers if required by the operating system. Configure serial communication parameters (baud rate, parity, data bits, stop bits, flow control) in the host application or terminal software to match the RS-232 device settings.

Recommendations

For reliable operation, use the cable in environments free of excessive moisture and mechanical strain. When connecting to industrial equipment, verify signal ground and voltage compatibility and follow the device manufacturer’s guidance. If the host does not auto-detect the adapter, obtain the appropriate driver from the system or adapter vendor.
