Delock USB-A to 2x Serial DB9 RS-232 Adapter – Compact Dual-Port Serial Interface
The Delock 63950 is a USB 2.0 adapter that converts a single USB-A port into two independent RS-232 serial connections via DB9 connectors. It enables legacy serial devices to connect to modern computers without additional interface cards.
Two RS-232 DB9 ports provide simultaneous connectivity for serial peripherals
USB 2.0 interface ensures plug-and-play compatibility and stable data transfer
External form factor keeps the adapter compact and desk-friendly
24 months manufacturer warranty provides long-term reliability for serial connectivity
What sets the Delock 63950 apart
Unlike internal PCI serial cards, this external adapter requires no opening of the computer case and no driver installation beyond standard USB 2.0 support. The dual-port design allows two serial devices to operate concurrently from a single USB-A port, reducing cable clutter and hub dependency.
Ideal for...
Users who need to connect legacy RS-232 equipment — such as industrial sensors, measurement devices, or serial printers — to laptops or desktops that no longer feature native serial ports. The compact external design suits desk setups where space is limited and a clean cable layout matters.
