Lindy Sub D-9/Sub D-9 Serial Cable Grey 20 m

The Lindy Sub D-9/Sub D-9 20m Grey serial cable provides a straightforward wired connection between devices that use 9-pin D-sub (Sub D-9) ports. With a 20-metre length and grey outer jacket, the cable is designed for extended runs where a stable RS-232 style serial link is required. High-quality molded connectors on both ends and a shielded conductor arrangement reduce interference and signal loss over longer distances, enabling consistent data transfer in office, lab or industrial environments.

Advantages

This 20 metre Sub D-9 cable features robust molded housings and secure locking screws to maintain a reliable mechanical and electrical connection. The shielded construction provides improved resistance to electromagnetic interference compared to unshielded leads, and the full metal connector shells enhance durability during repeated insertion and removal. The neutral grey jacket aids discreet routing in professional installations.

Suitable for

• Connecting computers, legacy equipment and instrumentation with 9-pin D‑sub serial ports
• Serial device configuration and console access in server rooms and networking closets
• Laboratory setups and industrial control systems requiring a long, stable serial link
• Point-to-point data transfer between POS terminals, barcode scanners, and controllers

Key specifications

• Cable type: Serial Sub D-9 to Sub D-9
• Length: 20 metres
• Connector gender: 9-pin male/female or as specified for direct Sub D-9 connection
• Shielding: Overall shield to reduce EMI
• Jacket colour: Grey
• Connector housing: Molded with screw-locks for secure fastening

How to use

Identify the 9-pin D-sub serial ports on both devices and align the connectors before seating them. Hand-tighten the screw-locks to secure the connection; avoid over-tightening to prevent damage. Route the cable away from high-voltage power runs and sources of strong electromagnetic interference where possible. For longer-term installations, use cable ties or clips to support and protect the cable along its path.

Recommendations

For reliable long-distance serial communication, verify pinout compatibility between connected devices and test the link with diagnostic software or loopback checks. If communication errors occur, inspect connector seating, shielding continuity and replace any damaged sections. Keep the cable dry and avoid sharp bends to preserve signal integrity over time.
