DELOCK 64307 Serial Cable USB Type-C to RS-232 (D-Sub 9) Black 0.25 m

DELOCK 64307 is a 0.25 m cable that converts a USB Type-C port into a single RS-232 D-Sub 9 (DB9) serial connection. The black cable provides a direct wired interface for legacy devices such as printers, measuring instruments, controllers, POS systems and routers, allowing data transfer, configuration and diagnostics over a standard serial link.

Advantages

The adapter offers a compact, low-profile connection with gold-plated contacts for reliable signal transmission and corrosion resistance. It uses a Prolific PL2303 GT chipset for USB-to-serial conversion and supports common serial data formats. Its short 0.25 m length reduces cable clutter and is supplied as a single unit ready for immediate use.

Suitable for

• Connecting printers and measuring instruments with RS-232 ports
• Configuring routers, switches and industrial controllers
• POS systems and legacy point-to-point serial devices
• Field diagnostics and short-distance data transfer

When it may not be suitable

This cable is intended for short, direct serial connections; its 0.25 m length limits use where longer runs are required. It provides a single DB9 male serial connector and is not suitable where multiple serial ports, DB9 female connections or RS-485/TTL voltage levels are needed.

• Supported data bits: 5, 6, 7, 8
• Conductor AWG: 28/24
• Connector contact plating: gold
• Colour: black
• Quantity: 1 piece

How to use

Plug the USB Type-C male end into a compatible host port and connect the DB9 male serial end to the RS-232 device using the appropriate mating connector. Install any required drivers for the Prolific PL2303 GT chipset on the host system if they are not already present. After driver installation the serial port appears to the operating system and can be accessed by terminal, configuration or diagnostic software using the appropriate baud rate and serial settings.

What to consider before purchase

• Ensure the host has a USB Type-C port that supports data connections.
• Verify the target device uses RS-232 signaling and a DB9 male/female match or adapters are available.
• Confirm required cable length — 0.25 m is for short, direct connections.
• Check operating system driver support for the Prolific PL2303 GT chipset.

Usage recommendations

For reliable communication, use correct serial settings (baud rate, parity, data bits and stop bits) matching the connected device and avoid excessive bending near the connectors. If a DB9 female is required, use a compatible gender changer or adapter; for longer runs consider longer shielded serial cables or signal repeaters.
