Port savers can prevent damage to the port connectors on your equipment that can be caused by repeated plugging and unplugging of connecting cables and adapters. They can also be used as in-line couplers to connect two similar cables to make a single effectively longer cable.This 9-pin DE-9 (DB-9) adapter is incorrectly labeled as a Gender Changer. However, it is actually a port saver/in-line coupler for DE-9 (DB-9) connections. It has nut connectors on one end and screw connectors on the other for securing it to panel and line connectors.
