Serial connection cable DIGITUS D-Sub9 male to D-Sub9 male, 2 m, beige

The DIGITUS Serial connection cable D-Sub9 male to D-Sub9 male, 2 m, beige provides a straightforward wired link for RS-232 and other legacy serial interfaces. With two molded 9-pin D-Sub male connectors and a 2-metre flexible jacket, the cable is designed to connect computers, routers, industrial controllers, measurement instruments and other devices that use DB9 serial ports. The beige outer jacket and secure connector shells offer a tidy, reliable physical connection for device configuration and data transfer tasks.

Advantages

This serial cable delivers a direct DB9-to-DB9 connection without adapters or additional wiring, which simplifies setup and reduces points of failure. Molded connector ends provide strain relief and help protect the soldered contacts, while the 2 m length balances reach and signal integrity for typical installation scenarios. The cable’s construction supports stable serial communication and straightforward device-to-device connections.

Suitable for

• Connecting PCs to serial peripherals such as modems and serial printers
• Linking routers, switches or network equipment with DB9 console ports
• Interfacing industrial controllers, PLCs and measurement devices
• Device configuration, firmware updates and serial data logging

Key specifications

• Connector type: D-Sub 9-pin male to D-Sub 9-pin male
• Cable length: 2 metres
• Jacket colour: beige
• Cable type: serial communication (RS-232 compatible wiring)
• Connector design: molded ends with strain relief

How to use

Ensure both devices are powered down or in a safe configuration for connection. Align the 9-pin male connectors with the DB9 female ports on each device and gently insert until the connector seats. Secure the connectors using the thumb screws or fastening hardware on the D-Sub shells to prevent movement. After physical connection, power devices and configure serial communication parameters (baud rate, parity, data bits, stop bits and flow control) to match on both ends for proper communication.

Usage recommendations

For reliable communication, keep cable runs away from strong electromagnetic interference sources such as large motors, fluorescent lighting or unshielded power cables. Use the 2 m length to position equipment within a practical distance and avoid unnecessary cable tension; inspect connectors periodically for corrosion or bent pins before use.
