Description

StarTech GC9SF Slim DB9 Gender Changer

Overview

The StarTech GC9SF is a compact gender changer designed to adapt a serial cable's connector type. This unit features two slimline DB9 female connectors, allowing you to join two DB9 male cables or convert a male port to female. Its slim profile is ideal for tight spaces where standard gender changers might not fit, such as behind rack-mounted equipment or within console server enclosures. The GC9SF model facilitates direct serial communication for devices like industrial controllers, legacy diagnostic tools, or network console ports where a simple physical connection change is required.

Compatibility

This gender changer is compatible with any standard DB9 serial port and cable configuration. It functions as a passive adapter, requiring no drivers or software. It is suitable for use with serial devices including, but not limited to, industrial automation equipment, point-of-sale systems, network switches, routers, and older computer peripherals that utilize a DB9 serial interface.

Installation Notes

The GC9SF requires no special tools for installation. Simply connect a DB9 male cable to one end and another DB9 male cable to the other end to achieve a female-to-female connection. The slim design minimizes protrusion from the connected device or cable.
