RS232 Cable ROLINE DB9 M - F 1.8 m

The ROLINE RS232 Cable DB9 M - F 1.8 m is a grey RS232 extension cable with a 9‑pin D‑Sub (DB9) male connector on one end and a 9‑pin D‑Sub (DB9) female connector on the other. It is intended for serial data connections, for example to connect devices with an IBM AT‑style serial interface or to link a serial device to a switchbox. All signal lines are wired 1:1 and the screen conductor is connected to the foil shield and both connectors to ensure proper shielding and signal integrity.

Advantages

This 1.8 m ROLINE DB9 cable provides a straightforward, fully wired RS232 connection with one‑to‑one pin mapping, reducing wiring complexity when extending or connecting serial devices. The integrated foil shielding and screen connection at both connectors help minimise electromagnetic interference and maintain stable data transmission over the cable length. The male‑to‑female configuration allows direct connection between compatible serial ports and peripheral devices.

Suitable for

• Connecting computers or controllers with RS232/IBM AT serial ports to peripherals
• Linking a serial device to a switchbox or serial adapter
• Extending an existing DB9 serial connection up to 1.8 m

How to use

Plug the DB9 male connector into the RS232 serial port of the source device and connect the DB9 female connector to the target device or switchbox. Ensure both devices are powered off when making the physical connection if the equipment manufacturer recommends it. Verify the serial communication settings (baud rate, parity, data bits, stop bits and flow control) in the devices' software or firmware to match for successful data exchange.

Recommendations

Use this cable for short to medium length RS232 connections in industrial, commercial or lab environments. Avoid routing the cable alongside high‑voltage power lines to reduce interference; if necessary, use separate conduits or additional shielding. Inspect connectors for bent pins before connecting and store the cable coiled without sharp bends.
