DeLOCK 86578 Serial Cable Black 1 m RS-232 Sub-D9

The DeLOCK 86578 is a 1 m RS-232 Sub-D9 serial cable in black designed for connection between devices that use the RS-232 interface. The cable provides a standard Sub-D9 connector on each end and is intended to deliver stable serial data transmission for equipment such as modems, routers, industrial controllers and legacy computer ports. Its compact length and classic black jacket make it suitable for rack installations, desktop setups and point-to-point connections where a short, reliable cable is required.

Advantages

The cable offers reliable physical connectors designed for repeated insertion and removal, maintaining consistent contact for serial communication. Its 1 meter length reduces excess cable clutter while providing sufficient reach for nearby devices. The black outer jacket provides a neutral appearance that integrates into professional or industrial environments. Constructed for standard RS-232 usage, it supports straightforward, plug-and-play connection without the need for additional adapters when both devices use Sub-D9 connectors.

Suitable for

• Connecting computers, terminals or legacy hardware with RS-232 Sub-D9 ports
• Linking modems, routers or serial peripherals for configuration and data exchange
• Industrial control panels and PLCs that require short serial connections
• Test benches and service desks where compact, predictable cabling is needed

Key specifications

• Interface: RS-232 (Sub-D9).
• Connector type: Male-to-Male Sub-D9 standard connectors.
• Length: 1 meter.
• Color: Black outer jacket.
• Purpose: Serial data transmission between RS-232 devices.

How to use

To use the cable, align the Sub-D9 connectors with the device ports and insert each connector until the screws (if present) can be tightened to secure the connection. Ensure both devices are powered off or configured according to manufacturer guidelines before making connections if required. After connecting, configure serial port parameters (baud rate, parity, data bits, stop bits and flow control) on both devices to match for successful communication. The cable is intended for direct point-to-point serial links and does not provide signal conversion; confirm both endpoints support RS-232 signaling.

Recommendations

For stable operation, avoid routing the cable alongside high-voltage power lines or sources of strong electromagnetic interference. Keep the cable length appropriate for the installation — this 1 m cable is optimized for short runs. Periodically inspect connector screws and contacts for secure fit and signs of wear if the cable is frequently connected and disconnected.
