Cablu serial DeLOCK 86574 negru 2m RS-232 Sub-D9

The DELOCK 86574 Black 2m RS-232 Sub-D9 serial cable is a two-meter connection cable designed for reliable serial data transmission between devices equipped with Sub-D9 (DB9) RS-232 ports. Constructed with durable connectors and a flexible black jacket, the cable supports point-to-point connections for peripherals such as printers, modems, industrial controllers, and legacy COM-port equipment. The 2 m length gives room for flexible device placement while maintaining signal integrity over short to moderate distances.

Advantages

This RS-232 Sub-D9 cable features secure metal-shell connectors that reduce contact wear and ensure consistent transmission. The cable jacket offers mechanical protection and flexibility for routing in desktop and rack environments. Its standard pinout and stable construction provide compatibility with a wide range of serial devices without the need for additional adapters. The two-metre length balances reach and signal stability for typical serial applications.

Suitable for

• Connecting serial printers and POS devices
• Linking external modems to computers or routers with RS-232 ports
• Interfacing industrial equipment, PLCs and instrumentation with control systems
• Communicating with legacy hardware and diagnostic consoles

Key specifications

• Cable type: RS-232 serial cable with Sub-D9 (DB9) connectors
• Length: 2 meters
• Connector gender: male-to-female or standard straight Sub-D9 configuration (as typical for RS-232)
• Color: black
• Construction: molded connector shells with strain relief and insulated multi-conductor cable
• Application: point-to-point serial communication for data, control and diagnostics

How to use

Identify the RS-232 Sub-D9 ports on both devices and align the connector pins before inserting. Hand-tighten the connector screws to secure the connection and prevent loosening during use. Route the cable to avoid sharp bends and high-tension points; use cable ties or clips for neat installation. Configure the devices for matching serial settings (baud rate, parity, data bits, stop bits, flow control) to establish communication. If communication fails, verify cable continuity and correct pinout against the connected equipment's requirements.

Recommendations

Use the cable within typical indoor environments and avoid exposure to excessive heat, moisture or mechanical stress. For installations near heavy electrical equipment or long cable runs, consider shielding or alternative cabling to reduce interference. Regularly inspect connector contacts for corrosion and ensure screws are tightened to maintain reliable serial connections.
