RS232 Serial Port to RJ45 Crystal Head Cable This cable provides a direct RS232 serial connection between a DB9 (9pin) port and an RJ45 console port. The RJ45 end uses a crystal head and is nonrotating for stable, reliable plugin. Key features and benefits Functionality: Converts a standard RS232 DB9 serial port to an RJ45 console port, enabling direct communication between devices that provide RS232 and those with RJ45 serial interfaces. Compatibility: Suitable for equipment that uses RS232 DB9 connections and devices with RJ45 serial console ports, including networking gear and PCs with compatible interfaces. Connectors and orientation: One end is a DB9 male (9pin) connector; the other end is an RJ45 crystal head (RJ45) connector. The RJ45 end is nonrotating. Performance: Provides a straightforward RS232 serial link for console access and basic serial communication between compatible devices. Size and form: Compact cable with standard DB9 and RJ45 connectors; designed for easy routing and quick connections. Materials: Standard RJ45 modular plug and DB9 connector assembly, designed for durability in typical usage environments. Reliability: Simple, direct wiring minimizes potential connection issues and setup complexity. Specifications and compatibility Interface: RS232 from a DB9 (9pin) serial port to an RJ45 (male) console port End connectors: DB9 male to RJ45 crystal head Cable type: RS232 Serial Port to RJ45 Crystal Head Cable Head type: Nonrotating RJ45 plug 3 practical use scenarios Network equipment setup: Connect a PC or laptop with a DB9 serial port to a network switch or router that exposes an RJ45 console port for initial configuration and management. Device maintenance and diagnostics: Link a PC to embedded devices or industrial controllers that use RJ45 serial interfaces to perform diagnostics, parameter changes, or firmware updates. Lab and development testing: Use in a development lab to connect serial devices to a workstation for data collection, testing, and debugging without needing a USBtoserial adapter. Notes This cable is designed for RS232 serial communication between a DB9 port and an RJ45 console port. Length and wire mapping are consistent with standard RS232 serial signaling. No rotating head or additional adapters are included; it is a straightforward DB9 to RJ45 cable as described.
