Extend Your Serial Connections Reliably
The XMSJSIY DB9 RS232 to RJ45 Extender Adapters (2-Pack) enable you to extend serial data transmission up to 66 feet (20 meters) using standard Cat5e or Cat6 Ethernet cables. These adapters are designed for bidirectional transparent transmission between serial ports and TCP/IP networks, offering a reliable solution for connecting legacy devices like desktop computers, digital machine tools, PDAs, and barcode scanners. They are USB-powered and require no external power source, ensuring a simple and convenient setup.
Constructed with high-quality alloy transmission ports to minimize impedance and interference, and encased in durable, environmentally friendly PVC material, these adapters enhance data transmission rates and quality. The interface is DB9 Male to RJ45 Female (9-pin/8P8C). For optimal performance and full functionality, these adapters are typically used in pairs, connecting two serial devices or a serial device to a network. Drivers are generally plug-and-play across Windows, macOS, and Linux systems.
These adapters are ideal for extending the reach of serial devices in industrial settings, labs, or retail environments where direct connection is not feasible. While they support up to 100m in ideal conditions, using them within 1-15 meters is recommended for maximum stability. All customs duties and GST are included in the listed price, with tracked delivery via ExpressBox.
Reliable Serial Extension for Indian Setups
Extend the reach of your industrial equipment, POS systems, or lab instruments across your Indian facility. These adapters use readily available Cat5e/Cat6 Ethernet cables to bridge distances up to 66ft (20m), overcoming the limitations of standard DB9 ports. Unlike direct serial connections that are often too short, this solution offers flexibility in device placement. They are powered via USB, ensuring compatibility with standard laptops and PCs used in Indian businesses. The durable construction and high-quality components ensure stable data transmission, crucial for uninterrupted operations in demanding environments. Imported directly from authorized US retailers and partners, ensuring authenticity and quality for your critical infrastructure.
Who It's For vs. Who Should Skip It
Ideal for IT professionals, industrial automation engineers, and small business owners in India needing to connect legacy serial devices (like older printers, scanners, or control systems) to modern networks or extend their range. If you require a direct USB-to-serial connection without needing to extend over Ethernet, a simple USB-to-DB9 cable might be more suitable. This adapter is not designed for direct USB-to-serial conversion; it specifically extends existing RS232 signals over Ethernet cabling. Ensure your target devices have standard DB9 serial ports and that you are using compatible Cat5e/Cat6 cables.
