Description

StarTech NM9FF DB9 Female to Female Null Modem Adapter

Overview

The StarTech NM9FF is a passive adapter that converts a standard DB9 male serial port into a DB9 female port, effectively creating a null modem connection between two DTE devices. This is critical for direct serial communication between computers or between a computer and a serial peripheral that requires a crossover connection, such as older industrial equipment or specific network devices. Its compact form factor and white color make it suitable for clean installations where aesthetics matter, and the 2-inch length minimizes cable extension.

Compatibility

This adapter is compatible with any system requiring a DB9 female serial port for direct DTE-to-DTE communication. It functions as a passive adapter, so it does not require drivers and works with any operating system or hardware that supports RS-232 serial communication. It is commonly used to connect two computers directly for file transfer or remote control, or to interface with serial consoles on network switches, routers, and other IT infrastructure components. It's also used for connecting certain types of legacy industrial control systems or diagnostic equipment.

Installation Notes

No special installation is required beyond physically connecting the adapter between two serial cables. Ensure the connected devices are configured for serial communication and that the appropriate null modem configuration is established at the software level if direct PC-to-PC communication is intended. The adapter's small size and lightweight (1.1 oz) design mean it adds minimal strain to connected cables.
