The Cablexpert CCDB9RECEPTACLE is an internal COM port extension designed to add a DB9 serial port to your computer chassis. It features a female DB9 receptacle mounted on a gold-finished metal bracket, which allows for a secure fit into a standard expansion slot. Connecting to the motherboard via a 25 cm grey ribbon cable with a 2x5 pin IDC connector, this adapter provides a reliable physical link for legacy serial devices. It is a practical solution for users who need to maintain connectivity with older hardware while keeping the connection neatly organized within the system case.
