StarTech AT925FM DB9 Female to DB25 Male Adapter

Overview

The StarTech AT925FM is a passive adapter designed to bridge serial communication interfaces. It converts a standard DB9 female connector to a DB25 male connector, enabling compatibility between devices with different serial port configurations. This adapter is useful for connecting legacy serial peripherals, such as older industrial equipment or specific diagnostic tools, to systems that may only offer a DB25 port, or vice-versa. Its compact form factor ensures it does not add significant bulk to your cable runs.

Compatibility

This adapter is compatible with any serial device or system that utilizes a DB9 serial port and requires a DB25 serial connection, or vice-versa. It is commonly used in IT, industrial automation, and networking environments where legacy serial interfaces are still present. For example, it can connect a serial console server with a DB25 port to a network switch that has a DB9 console port, or adapt a serial printer to a computer with a different serial port type.

Installation Notes

No drivers or software are required for the AT925FM. Installation involves simply plugging the DB9 female end into the corresponding male connector and the DB25 male end into the corresponding female connector. Ensure a secure connection is made on both ends to maintain signal integrity. The adapter does not require external power.
