Product information

Description

ATEN ku31-232 is a USB to RS-232 converter with an integrated 1.8 m cable and a USB-C connector. It enables connection of devices that use an RS-232 serial port to modern hosts with USB-C, providing a wired serial interface for tasks such as device programming, firmware upgrades and data communication with legacy equipment.

Advantages

The converter supports data rates up to 1 Mbps and is built around an FTDI FT232RL chipset, ensuring broad driver support and stable serial communication. It includes drivers (CD) for legacy systems, does not require IRQ configuration, and features a 9-pin D-sub (Canon) male connector. The integrated 1.8 m cable and compact design simplify installation with laptops and newer devices that have USB-C ports.

Suitable for

  • Connecting modems and serial printers to USB-C hosts
  • Programming and firmware updates of embedded devices
  • Connecting POS terminals, barcode readers and legacy PDAs
  • Industrial controllers and serial equipment integration

Key specifications

  • Interface: USB-C (host) to RS-232 (9-pin D-sub male)
  • Cable length: 1.80 m (integrated)
  • Chipset: FTDI FT232RL
  • Maximum data rate: up to 1 Mbps
  • Operating system support: Windows 98/ME/2000/XP/Vista/7/8/10 and macOS
  • Color: black

How to use

Connect the USB-C end of the ATEN ku31-232 to the host device. Attach the 9-pin D-sub male connector to the RS-232 serial port of the peripheral. Install drivers provided on the included CD or download the latest FTDI drivers from the FTDI website if required. After driver installation the serial port will appear to the host as a standard COM port for use with terminal software, programming tools or communication applications.

Usage recommendations

For reliable operation, ensure correct COM port settings (baud rate, parity, data bits and stop bits) that match the connected device. If using modern operating systems, download updated FTDI drivers from the manufacturer rather than relying on legacy CD media.
