USB to RS-232 adapter for legacy serial devices

This USB to RS-232 adapter provides a DB9 serial port for connecting legacy equipment to modern computers. It suits engineers, technicians and hobbyists who need to configure routers, switches, industrial controllers or older scientific instruments. The 1.5 m cable length gives enough reach for bench work without excess slack.

DB9 connector with 1.5 m cable for direct connection

The nine-pin DB9 connector plugs straight into standard RS-232 ports, eliminating the need for gender changers or null-modem cables. The fixed 1.5 m length limits placement flexibility in larger racks or when equipment is farther apart. Buyers who need longer runs or multiple simultaneous serial ports should consider other solutions.

Highlights

  • 5 m cable reaches distant serial equipment
  • USB connection powers the adapter without an external supply
  • DB9 male port fits legacy nine-pin COM devices
  • RS-232 signalling enables communication with industrial and networking gear

Questions about this item

Will the 1.5 m USB to RS-232 adapter reach my legacy DB9 equipment without an extension cable?

The cable is 1.5 metres (59 inches) long, so measure from your USB port to the DB9 device to confirm the distance is covered.

How can I verify the RS-232 link is active after plugging in the DB9 connector?

Open Device Manager, locate the new COM port under Ports (COM & LPT), then run a terminal program to send data and watch the TX/RX LEDs blink.
