Serial Cable DeLOCK 86575 Black 3 m RS-232 Sub-D9

The DeLOCK 86575 Black 3 m RS-232 Sub-D9 serial cable provides a straightforward physical connection for devices that use RS-232 serial communication. With a three-metre length and conventional Sub-D9 connectors, this cable enables point-to-point data exchange between computers, industrial controllers, peripherals and measurement instruments that accept a 9-pin RS-232 interface. Its plain black jacket and standard connector layout make it compatible with a wide range of legacy and modern equipment that retain serial ports.

Advantages

The cable offers a fixed 3 m reach suitable for setups where a short to medium distance between devices is needed. Its standardized Sub-D9 connectors ensure reliable mechanical mating and straightforward installation without special adapters for equipment that supports RS-232. The construction is designed for stable signal transmission and repeated plug cycles, providing consistent serial communication for configuration, monitoring and control tasks.

Suitable for

• Connecting PCs or laptops to serial-enabled peripherals such as modems and printers
• Linking industrial controllers, PLCs and HMIs for configuration and diagnostics
• Interfacing measurement instruments and laboratory equipment with serial ports
• Firmware updates and serial console access on networking or embedded devices

Key specifications

• Cable type: RS-232 serial cable with Sub-D9 (9-pin) connectors
• Length: 3 meters
• Color: black outer jacket
• Connector gender/configuration: standard male/female Sub-D9 (9-pin) interface
• Use: point-to-point serial data transmission for RS-232-compatible devices

How to use

Connect the Sub-D9 connectors to the RS-232 ports on the two devices you want to link, making sure the connector orientation matches the port. Secure the connectors by fastening any thumbscrews or retaining hardware if present to prevent accidental disconnection. Configure the serial parameters (baud rate, parity, data bits, stop bits, and flow control) on both devices to the same values before starting communication. For equipment that requires a specific cross-over wiring (null modem) or pin assignment, verify the pinout compatibility with the device documentation before use.

Recommendations

For reliable operation, avoid routing the cable near high-voltage power lines or sources of strong electromagnetic interference. Keep the cable free from sharp bends and excessive mechanical stress; secure it with cable ties at gentle bends if needed. When using in industrial environments, check connector fastening regularly and confirm serial settings after any hardware changes.
