SKU CH-WQDV-9FEXB

Connects a DB9 serial device to a USB 2.0 Type-A port with a 25 cm cable

  • Connect legacy serial devices via USB 2.0
  • DB9 female to USB-A female converter cable
  • Compact 25 cm length for tidy setups
  • Supports RS232 communication standard

Serial adapter for legacy devices

This 25 cm cable converts a DB9 serial port to a USB 2.0 Type-A connection, letting older industrial equipment or networking gear communicate with modern computers. It suits technicians and hobbyists who need a short, direct link without extra hubs or gender changers.

Compact build for tight spaces

The moulded connectors and 25 cm length keep cable clutter low inside cabinets or behind racks where depth is limited. DB9 and USB Type-A ends are both female, so the adapter plugs straight into existing cables without additional couplers.
