RS232 USB to DB9 HID Keyboard Converter Cable with CH9328 

PCM-KW-559 is a USB to DB9 male HID keyboard converter cable designed to convert RS232 serial data into standard USB HID Keyboard input. The cable integrates a CH9328 IC chip to process serial data and output corresponding keyboard scan codes, allowing a connected host to receive serial information as keyboard input rather than through a conventional COM port.

The DB9 male interface connects directly to compatible RS232 serial equipment, while the USB interface connects to the host system. This Serial to HID Keyboard Converter is suited to legacy equipment and systems that accept USB keyboard input but do not provide direct RS232 or COM port support.
