## Long description

The InLine Serial AT-Adapter 25 Pin female / 9 Pin Sub-D male is a compact adapter for serial communication ports and cables. It provides a 25-pin female (DB-25) interface converted to a 9-pin Sub-D male (DB-9) connector, enabling connection between legacy RS-232 devices and equipment that uses the smaller 9-pin serial port. The adapter comes in beige and is intended for straightforward, passive signal routing without additional power or drivers.
Advantages

It supports reliable wired RS-232 connections for legacy devices, is plug-and-play with no software required, and its neutral beige colour blends with standard serial cabling and equipment.
Suitable for
Connecting older printers, modems or industrial equipment with DB-25 ports to DB-9 serial ports
