DeLOCK Adapter USB 2.0 Type-A to Serial RS-232 D-Sub 9 pin 2.5 kV Galvanic Isolation 2 m

The DeLOCK USB 2.0 Type-A to Serial RS-232 adapter provides a DB9 connector with 2.5 kV galvanic isolation and a 2 m cable, enabling reliable serial communication between a computer and devices that use RS-232. It is compatible with printers, measuring instruments, controllers, IoT devices and other equipment requiring a standard RS-232 interface.

Advantages

This adapter offers galvanic isolation up to 2.5 kV to protect connected equipment from ground loop currents and electrical interference. The 2 m cable gives flexible placement and easy connection to devices, while the standard DB9 (D-Sub 9) serial interface ensures broad compatibility. The black housing and USB Type-A plug provide a straightforward USB-to-serial solution for systems with USB 2.0 ports.

Suitable for

• Connecting legacy printers and point-of-sale devices to modern PCs
• Interfacing measuring instruments and laboratory equipment
• Linking industrial controllers and automation hardware
• Connecting IoT devices and embedded systems that use RS-232

How to use

Plug the USB Type-A connector into an available USB 2.0 port on your computer. Connect the DB9 serial connector to the RS-232 port of the target device (printer, controller, instrument). Install any required drivers according to the operating system prompts or the manufacturer's instructions, then configure the serial port settings (baud rate, parity, data bits, stop bits, flow control) in your application or OS to match the connected device.

Recommendations

For reliable operation, ensure proper driver installation and matching serial port parameters. Avoid placing the cable near strong electromagnetic sources and confirm that the device side connector type (male or female) matches your equipment. Use the galvanic isolation feature to reduce risk from ground loops in mixed-ground systems.
