DeLOCK 86573 1m RS-232 Sub-D9 Serial Cable Black

The DeLOCK 86573 is a 1 metre RS-232 Sub-D9 serial cable in black designed for reliable point-to-point data transmission between devices with standard 9-pin serial ports. Constructed with quality connectors and shielding, the cable provides stable connections for serial communication in desktop, industrial, and embedded environments. Its compact length makes it suitable for tidy installations where short, direct cabling is required.

Advantages

This RS-232 Sub-D9 cable offers durable metal-backed connectors and secure pin alignment for consistent signal contact. The cable’s shielding reduces electromagnetic interference and preserves data integrity over the full 1 m length. Its flexible outer jacket supports repeated routing and repositioning without compromising performance.

Suitable for

• Connecting PCs, laptops or terminals to serial devices such as modems and routers
• Linking industrial controllers, PLCs and measurement instruments with RS-232 ports
• Serial configuration of networking equipment and serial consoles on servers
• Embedded system development and debugging via serial ports

Key specifications

• Cable type: RS-232 serial cable
• Connector type: 9-pin Sub-D (male/female depending on model end configuration)
• Length: 1 metre
• Colour: black
• Construction: shielded cable with metal-backed connector housings
• Intended use: data transmission for RS-232 serial interfaces

How to use

Connect the Sub-D9 connectors to the matching RS-232 serial ports on each device, ensuring correct orientation and secure screw fastening where applicable. Confirm COM port settings and communication parameters (baud rate, parity, data bits, stop bits) on both devices before initiating data transfer. Route the cable away from high-voltage power lines and sources of strong electromagnetic interference to maintain signal quality.

Recommendations

For reliable operation, use this cable for short-distance serial links and avoid bending the cable excessively near the connector ends. Periodically inspect connector contacts and screws for tightness and signs of corrosion in humid or industrial environments. If longer runs or higher immunity to interference are required, consider using a differential or fiber-based serial solution.
