DeLOCK 86603 Serial Cable Black 3 m RS-232 Sub-D9

The DeLOCK 86603 black serial cable, 3 m in length, provides a standard RS-232 Sub-D9 connection for reliable serial communication between computers, industrial controllers and peripheral devices. The cable is configured to fit equipment that uses a 9-pin D‑sub connector and is intended for straightforward point-to-point data transmission in commercial, technical and industrial environments.

Advantages

This serial cable offers a durable jacket and reliable connector contact to ensure stable signal transmission over the full 3 m length. The standardized RS-232 Sub-D9 interface simplifies connection to legacy hardware and instrumentation without additional adapters. The black color and conventional construction allow easy cable routing and integration into existing cabling setups while maintaining consistent electrical characteristics for serial data lines.

Suitable for

• Connecting PCs or laptops with RS-232 ports to serial devices
• Linking industrial controllers, PLCs or CNC machines to monitoring equipment
• Programming or configuring network devices and routers with console ports
• Connecting measurement instruments, serial printers and barcode scanners

Key specifications

• Connector type: 9-pin D-sub (Sub-D9) RS-232
• Cable length: 3 metres
• Color: black
• Application: serial data transmission (RS-232)
• Construction: shielded conductors for reduced interference

How to use

Connect one end of the Sub-D9 cable to the RS-232 port of the host device and the other end to the serial port of the target device, making sure screw or thumbscrew fasteners are tightened to secure the connection. Configure the communication parameters on both devices (baud rate, parity, data bits, stop bits, and flow control) to match each other before initiating data transfer. Verify signal integrity and communication using terminal software or device-specific diagnostics.

Recommendations

Avoid routing the cable alongside high-voltage power lines or sources of strong electromagnetic interference to maintain signal quality. For long-term installations, ensure strain relief at connector ends and check connector contacts periodically for oxidation or looseness to preserve reliable RS-232 communication.
