Serial cable DELOCK 85524, D-Sub 25 pin to D-Sub 9 pin, 2 m, beige

DELOCK 85524 is a 2 m beige serial cable with a D-Sub 25-pin connector on one end and a D-Sub 9-pin connector on the other. It is designed for RS-232 connections and for linking legacy serial devices to computer ports or serial adapters. The cable provides a straightforward wired connection for data transfer, device configuration and maintenance between computers, routers, modems, industrial controllers and measurement instruments.

Advantages

The cable offers a fixed-pin wired mapping between a 25-pin D-Sub plug and a 9-pin D-Sub plug, enabling direct serial communication without additional converters. Its 2 m length balances reach and signal integrity for typical desktop and rack installations. The neutral beige jacket supports conventional equipment aesthetics and easy identification in mixed-cable environments. Constructed for standard RS-232 signalling, the cable maintains compatibility with a wide range of legacy hardware and serial interfaces.

Suitable for

• Connecting PCs to legacy serial printers, modems or terminals
• Serial console access to routers, switches and network equipment
• Configuration and maintenance of industrial controllers and instrumentation
• Data transfer between devices using RS-232 signalling

Key specifications

• Cable length: 2 m
• Connector A: D-Sub 25-pin (male/female as per product type)
• Connector B: D-Sub 9-pin (male/female as per product type)
• Colour: beige
• Interface standard: RS-232 serial communication

How to use

Identify the appropriate D-Sub 25-pin and D-Sub 9-pin ports on your devices. Align the connectors and secure each connector by tightening any built-in screws or thumbscrews to ensure a stable mechanical and electrical connection. After connecting, configure the serial port settings on the host device—such as baud rate, parity, data bits and stop bits—to match the connected equipment. For serial console access, open a terminal application on the host and select the corresponding COM port.

Recommendations

For reliable performance, avoid routing the cable alongside high-voltage power lines or sources of strong electromagnetic interference. Use appropriate strain relief at connector ends and avoid sharp bends near the connectors. Verify port pinouts and serial settings before operation to prevent communication errors when connecting different generations of equipment.
