RS232 Cable ROLINE DB9 M - F 10 m

The ROLINE RS232 Cable DB9 M - F 10 m is a 10-meter serial cable with 9-pin D-Sub (DB9) connectors that provides a direct 1:1 wiring for reliable RS232 communication. It is intended for connecting devices with RS232 interfaces, such as legacy serial ports and switchboxes, and features a grey jacket and shield continuity through the screen conductor and foil shield connected to both connectors.

Advantages

The cable offers full pin-to-pin wiring (1:1) for straightforward signal mapping and a continuous screen connection that helps reduce electromagnetic interference. With standard DB9 male and female connectors, it is compatible with typical RS232 devices and switchboxes and its 10 m length provides flexibility for equipment placement in industrial and commercial environments.

Suitable for (tasks / use cases)

• Connecting PCs, terminals or industrial controllers with RS232 ports to peripherals or switchboxes
• Extending serial connections over a longer distance within control cabinets or between devices
• Maintenance and diagnostic connections to legacy equipment using DB9 interfaces

How to use

Identify the RS232 DB9 ports on both devices and align the male and female DB9 connectors. Secure the connectors by tightening the thumbscrews or screws if present. Ensure the pinouts on both devices are compatible with standard RS232 1:1 wiring. Route the cable to avoid sharp bends and strong sources of electromagnetic interference; maintain adequate slack to prevent strain on connectors.

Recommendations

For best performance, keep the cable away from high-voltage power lines and large motors. Verify device settings (baud rate, parity, stop bits) match on both ends before use. If signal issues occur over the 10 m run, check connector contacts and cable integrity.
