RS232 Cable ROLINE DB9 F - F 1.8 m

The ROLINE RS232 Cable ROLINE DB9 F - F 1.8 m is a 1.8 metre serial cable with two 9‑pin D‑Sub (DB9) female connectors designed for RS232 connections. It is intended to link devices that use standard serial ports, for example connecting an IBM AT‑style serial interface to a switchbox or other RS232‑equipped equipment. The cable is grey and wired with a 1:1 pin assignment to preserve standard serial signal mapping.

Advantages

The cable provides a direct 1:1 wiring of all nine DB9 pins, ensuring compatibility with devices expecting standard RS232 pinouts. The screen conductor is tied to the foil shield and to both connectors to reduce electrical interference. With its 1.8 m length the cable offers moderate reach suitable for typical desktop or rack setups while remaining flexible for installation in office and industrial environments.

Suitable for

• Connecting RS232 serial devices with female DB9 ports
• Linking an IBM AT style serial interface to a switchbox or serial extender
• Serial communication between computers, PLCs, routers or instrumentation with DB9 connectors

How to use

Plug each DB9 female connector onto the corresponding male DB9 port of the devices you wish to connect. Ensure secure mechanical fastening if the devices provide fastening screws. Verify that both devices are configured for RS232 communication and that any required baud rate, parity, data bits and stop bits settings match on both ends before initiating data transfer.

Usage recommendations

The cable is intended for short to medium length RS232 connections in office or industrial settings; avoid routing it parallel to high‑voltage power lines for extended distances to reduce the risk of interference. For long distance serial links or environments with strong electrical noise consider using proper line drivers, differential converters or shielded conduits.
