USB To DB9 HID Keyboard Cable

The USB-to-DB9 HID Keyboard Cable features a built-in CH9328 serial-to-HID keyboard chip, which receives RS232 serial data via the DB9 interface and emulates it as standard USB keyboard input. The computer recognizes it as an HID keyboard device, requiring no driver installation to achieve true plug-and-play functionality. The PCM-KW-559 features a USB-A male connector at one end and a standard DB9 male connector at the other; constructed with pure copper conductors and a PVC jacket, it typically measures 1 meter in length, ensuring stable signal transmission. It is widely applicable for connecting traditional serial devices-such as barcode scanners, industrial instruments, and electronic scales-by directly converting serial data into keyboard input.
