Product information

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

This adapter offers a simple, space-saving solution to convert a 25-pin serial connector to a 9-pin Sub-D male connector. 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
Laboratory or workshop setups that require serial interface conversion
Field service and maintenance tasks involving legacy RS-232 devices

Key specifications

Connector 1: 25-pin female (DB-25)
Connector 2: 9-pin Sub-D male (DB-9)
Product colour: Beige
Brand: InLine
MPN: 31249
EAN: 4043718000142

How to use

Connect the DB-25 female end to the corresponding 25-pin cable or device and insert the DB-9 male connector into the 9-pin serial port on the target device. Ensure connectors are aligned and fasten any screws to secure the connection. No drivers or external power are required; the adapter passes through standard RS-232 signals.

Usage recommendations

Use the adapter for short to moderate cable lengths typical for RS-232 communication and avoid exposure to moisture or mechanical stress. Verify pinout compatibility when connecting non-standard or custom-wired cables to prevent signal mismatch.
