Product information

Description

The InLine USB-C to serial adapter cable bridges the gap between modern computer systems and legacy hardware by offering a seamless connection from a USB Type-C port to an RS232 serial interface. Measuring 1.8 meters in length and featuring a sleek black design, this adapter cable is equipped with a USB Type-C male connector on one end and a DB9 male connector on the other. It integrates a reliable FTDI FT232RL chipset to ensure stable data transmission rates of 1 Mbps and higher, making it a dependable solution for linking older serial peripherals to contemporary laptops and desktop computers without traditional serial ports.

Advantages

This adapter cable efficiently creates an additional virtual COM port on your system, allowing uninterrupted communication with older hardware. The inclusion of a 9-pin Sub-D female to 25-pole Sub-D male adapter provides added flexibility for connecting both 9-pin and 25-pin devices. Designed for convenience, the cable supports remote wake-up and power management functions, ensuring efficient system operation and device responsiveness. Its robust build quality and standardized RS232 interface compatibility make it an essential tool for technicians and professionals who need to maintain legacy infrastructure alongside modern computing environments.

Suitable for

  • Connecting legacy modems, ISDN systems, and PBX telephone systems to modern computers
  • Interfacing with industrial machinery, automation systems, and programming consoles
  • Service work, on-site diagnostics, and IT maintenance involving older serial peripherals
  • Connecting legacy personal digital assistants and science instruments to USB-C ports

When it may not be suitable

This adapter cable is not designed for video output transmission and cannot be used to connect monitors or displays, despite the physical similarity of some D-Sub connections. It is also unsuitable for high-speed data storage applications or general USB peripheral expansion, as it is strictly engineered for serial communication protocols.

Key specifications

  • USB Type-C male connector
  • DB-9 male connector
  • Cable length: 1.8 meters
  • RS232 serial interface support
  • Data transfer rate of 1 Mbps and higher
  • FTDI FT232RL chipset
  • Includes 9-pin Sub-D female to 25-pole Sub-D male adapter
  • Supports remote wake-up and power management signals
  • Color: Black

How to use

To begin using the adapter cable, connect the USB Type-C end into an available port on your computer. Connect the DB9 end directly to your serial device, or attach the included 9-pin to 25-pin adapter if your peripheral requires a 25-pin connection. Ensure that the appropriate drivers for the FTDI chipset are installed on your operating system, which will automatically assign a new COM port. Once configured, you can operate your serial device through the standard communication software on your computer.

What to consider before purchase

  • Verify that your operating system is compatible with the FTDI FT232RL chipset
  • Check whether your serial device requires a 9-pin or 25-pin connection to utilize the included adapter
  • Confirm that your computer is equipped with an available USB Type-C port
  • Ensure your application requires an RS232 serial interface rather than a different communication standard

For optimal performance, ensure that the latest manufacturer drivers for the chipset are installed and avoid routing the 1.8-meter cable near strong electromagnetic sources that could cause signal interference.
