With support for various serial configurations, it adapts to the specific requirements of your connected equipment.

Ideal use cases

• Connecting legacy serial printers, scanners, or barcode readers to modern laptops.
• Configuring network switches, routers, and firewalls via console port.
• Interfacing with industrial control systems, PLCs, and CNC machines.
• Upgrading point-of-sale systems that rely on RS-232 peripherals.
• Laboratory data acquisition from older instruments.

Good to know

The adapter uses a standard USB Type-A connector and a DB9 male serial connector, so no additional gender changers are needed for most devices. The 15 kV ESD protection safeguards against electrostatic discharge, a common issue in industrial environments. Drivers for Windows, macOS, and Linux are readily available from the Prolific website or via automatic updates. Note that while the adapter is compatible with USB 2.0 ports, it operates at USB 1.1 speeds, which is sufficient for RS-232 communication.
