Black Box CBPS76000 DB9M to DB25F Screwlock Cable - 30ft
Overview
The Black Box CBPS76000 is a 30-foot serial cable designed to bridge the gap between DB9 male and DB25 female interfaces, featuring screwlocks for secure connections. This cable is critical for integrating legacy serial devices, such as older security system components or industrial control equipment, into modern infrastructure where DB25 ports may still be present or required for specific hardware. The 30-foot length provides ample reach for installations where devices are not co-located, ensuring flexibility without excessive cable management.
Compatibility
This cable is designed for direct connection between devices featuring a DB9 male serial port and devices requiring a DB25 female serial port. It is commonly used for connecting serial printers, modems, terminals, and certain types of industrial automation hardware. Its straightforward wiring scheme ensures broad compatibility with most serial communication protocols, provided the pinout matches the application requirements. Specific compatibility extends to systems and devices that utilize standard RS-232 serial communication and require this specific connector configuration.
Installation Notes
The integrated screwlocks on the DB9 connector ensure a firm, vibration-resistant connection, preventing accidental disconnections that could disrupt critical data flow. Ensure the DB9 male connector is properly seated in its female port and the screwlocks are tightened. The DB25 female connector is designed to mate with a DB25 male connector, typically found on peripherals or interface cards. Verify pinout compatibility for your specific application to avoid communication errors.
