Key Features & Advantages
-
DB9 RS232 Female Connector
One end features a standard 9-pin female DB9 connector, fully compatible with RS232 serial ports found on industrial equipment, PLCs, and legacy devices. The screw-locking mechanism ensures a secure, vibration-resistant connection, preventing accidental disconnections in industrial environments.
-
Dual USB Type-A Connectors
The other end splits into two standard USB Type-A male connectors, allowing connection to two USB ports on a computer. This dual USB design ensures stable power supply and reliable data communication, eliminating common issues with low-power serial adapters.
-
Purpose-Built for RS232 Debugging & Communication
The cable is designed to support standard RS232 signals (TX, RX, GND) for debugging, programming, and data transfer with serial devices. It is ideal for connecting to industrial control equipment, CNC machines, test instruments, and legacy serial peripherals.
-
Durable Industrial-Grade Construction
Built with high-quality stranded copper conductors and a thick black PVC jacket, this cable offers excellent resistance to wear, bending, and environmental damage. Molded strain relief at both the DB9 and USB ends prevents wire breakage, ensuring long-term reliability even with frequent use.
-
Plug-and-Play Compatibility
Designed to work with major operating systems (Windows, macOS, Linux) with standard USB-to-RS232 drivers, this cable provides seamless connectivity without complex configuration. It is perfect for industrial automation, laboratory testing, and maintenance tasks involving RS232 devices.
This DB9 RS232 to Dual USB Cable provides a reliable, dual-powered solution for connecting and debugging legacy serial devices with modern computers via USB.
