Serial connection cable ACT 3 metre 9 pin D-sub male - 9 pin D-sub male

The ACT 3 metre Serial 1:1 connection cable features 9 pin D-sub male connectors on both ends and a 3 m length to connect serial devices over moderate distances. Designed for direct, straight-through wiring, the cable provides a simple and durable link between equipment such as computers, modems, industrial controllers and serial peripherals. The beige outer jacket and standard 9‑pin male D‑sub plugs make the cable compatible with a wide range of legacy and industrial interfaces.

Advantages

The cable offers straightforward 1:1 pin mapping for predictable signal routing and easy installation. At 3 metres it balances reach and manageability for desktop and equipment-rack setups. The molded D-sub male connectors provide secure mating and strain relief, while the cable jacket resists everyday wear in office and light-industrial environments. Its simple construction ensures compatibility with standard RS-232 and other serial implementations that use 9‑pin D‑sub connectors.

Suitable for

• Connecting PCs or laptops to serial devices with 9‑pin D‑sub ports
• Linking modems, GPS units, or serial printers to host equipment
• Connecting PLCs, HMIs or industrial controllers in control cabinets
• Data transfer, configuration and diagnostic tasks for serial-enabled hardware

Key specifications

• Connector type: 9‑pin D‑sub male to 9‑pin D‑sub male
• Cable length: 3 metres
• Wiring: 1:1 (straight-through) pin configuration
• Outer jacket colour: beige
• Typical use: serial signal transmission (RS‑232 and similar)

How to use

Ensure both devices are powered down before connecting the 9‑pin D‑sub male ends to the corresponding serial ports. Align the D‑sub connector screws and tighten them by hand or with a small screwdriver to secure the connection. After connecting, power on the devices and configure serial communication settings (baud rate, parity, data bits, stop bits and flow control) on both ends according to device requirements. For diagnostic or configuration operations, verify COM port assignments and test communication using terminal software or device-specific utilities.

Usage recommendations

Avoid sharp bends and excessive tension along the cable to preserve connector integrity and signal quality. For installations in electrically noisy environments, keep the cable routed away from high-voltage power lines and large motors. When using the cable in permanent or semi-permanent installations, periodically check connector screws and the jacket for wear and replace the cable if physical damage is observed.
