STARTECH GC9SF DB9 Gender Changer F/F Data Adapter

DB9 Female-to-Female Gender Changer

The StarTech.com GC9SF is a slimline DB9 gender changer that converts a 9-pin male serial port into a 9-pin female connection. It provides a direct female-to-female interface for joining two male cables or adapting a male port on legacy equipment. The compact black adapter adds no cable length and weighs 0.03 kg.

Extending or Adapting Male DB9 Connections

This adapter suits technicians maintaining serial infrastructure who need to link two male-terminated cables or convert a male port for a female plug. It is not for situations requiring a male-to-female gender change, a male-to-male connection, or conversion to a different connector standard such as DB25 or USB.

DB9 Female Connector on Both Ends

The defining specification is the dual DB9 female pinout that accepts only 9-pin male connectors. Buyers must verify their cables or ports are male DB9 before purchase; the changer cannot mate with female ports or any other pin count.
