Black Box EDN12H-0025-MM RS232 Shielded Cable - Metal Hood DB9
Overview
The Black Box EDN12H-0025-MM is a 25-foot shielded RS-232 serial cable designed for environments where reliable data communication is critical. Its metal hood DB9 connector provides robust shielding against electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring data integrity for sensitive equipment. This cable is ideal for connecting industrial control systems, security devices, and legacy serial peripherals where signal integrity cannot be compromised. The EDN12H-0025-MM ensures a stable connection for point-to-point serial communication.
Compatibility
This cable is compatible with any device featuring a standard DB9 serial port that requires RS-232 communication. It is commonly used with industrial automation equipment, point-of-sale systems, network devices requiring console access, and older security system components that utilize serial data interfaces. The metal hood ensures a secure connection and grounding path, beneficial for equipment susceptible to electrical noise or requiring a stable ground reference.
Installation Notes
The metal hood on the DB9 connector allows for screw-locking to secure the connection and prevent accidental disconnection. Ensure the connector is properly seated and the locking screws are tightened to maintain optimal shielding and physical connection integrity. The cable's shielding is most effective when the metal hood is properly grounded, which is facilitated by the screw-locking mechanism.
