InLine Serial Extension Cable 9-pin Male to Female 1:1 Assigned Moulded Beige 2 m

The InLine Serial Extension Cable 9-pin Male to Female 1:1 Assigned Moulded Beige 2 m is designed to extend existing serial interface connections between computers, servers, and various peripheral hardware. Featuring a 9-pin male Sub-D connector on one end and a 9-pin female Sub-D connector on the other, this cable allows you to bridge distances without signal loss or alteration. It uses a 1:1 pin assignment to ensure direct, uncrossed data transmission, making it a dependable solution for maintaining stable communication between legacy and modern devices.

Advantages

This serial extension cable provides a reliable method for lengthening established RS232, RS422, or RS485 connections. The moulded connector design enhances mechanical stability at the connection points, protecting internal wiring from strain and daily wear. Its neutral beige color blends easily into office and industrial environments, while the standardized Sub-D layout guarantees broad compatibility with standard serial hardware. The direct 1:1 pin configuration prevents unexpected signal translation errors.

Suitable for

• Extending RS232, RS422, or RS485 serial connections
• Connecting legacy hardware to PCs or servers
• Office equipment and data switches
• Industrial automation and control systems

When it may not be suitable

This cable is not designed for null-modem or crossover communication where specific pins need to be swapped, as it utilizes a strict 1:1 pin assignment. Additionally, it is not suitable for modern high-speed consumer data interfaces such as USB, HDMI, or DisplayPort.

Key specifications

• Cable length: 2 m
• Connector 1: male 9pin Sub-D
• Connector 2: female 9pin Sub-D
• Assignment: 1:1
• Supported interfaces: RS232, RS422, RS485
• AWG wire size: 28
• Product colour: Beige
• Design: Moulded connectors

How to use

To use the cable, ensure that all connected devices are powered off to prevent electrical surges. Take the male 9-pin Sub-D connector and plug it into the female port of your computer, server, or existing serial cable. Take the female 9-pin Sub-D connector on the other end and attach it to the male port of your peripheral device. Tighten any thumbscrews on the connectors to secure the physical connection firmly. Once securely attached, power on your equipment and begin normal data transmission.

What to consider before purchase

• Verify that your devices utilize standard 9-pin Sub-D serial ports
• Confirm whether a 1:1 straight-through connection is required rather than a crossover or null-modem configuration
• Check that the 2-meter length is sufficient to span the distance between your connected equipment

Usage recommendations: Route the serial extension cable away from sharp edges, heavy foot traffic, and high-voltage power lines to prevent physical damage and electromagnetic interference. Ensure connectors are aligned straight before insertion to avoid bending the internal pins.
