Description

C2G 52188 25ft Null Modem Cable

Overview

The C2G 52188 is a 25-foot CMG-rated null modem cable designed for direct serial communication between two devices, such as configuring network equipment or connecting legacy serial peripherals. Its CMG rating indicates suitability for in-wall or riser applications, providing a cleaner installation for fixed deployments. This cable uses a DB9 male connector on one end and a DB9 female connector on the other, with internal wiring crossed over to facilitate a direct serial connection without requiring a modem. The 52188 model is critical for scenarios where direct device-to-device serial communication is necessary for initial setup, firmware updates, or diagnostic access.

Compatibility

This null modem cable is compatible with any two serial devices requiring a direct connection, including but not limited to: industrial control systems, legacy network switches and routers, serial printers, and certain security system components that utilize DB9 serial ports for configuration or data transfer. It is designed to interface with standard DB9 serial ports found on most computing and networking hardware.

Installation Notes

The CMG rating signifies that this cable is suitable for use within walls or between floors in commercial buildings, adhering to safety standards for plenum and riser spaces. Ensure connectors are securely fastened to prevent signal degradation. The cable's 25-foot length provides flexibility for routing within racks or across short distances between equipment.
