RS232 Cable ROLINE M - M 9 m

The ROLINE RS232 Cable M - M 9 m is a 9-metre serial cable with two 25‑pin D‑Sub (DB25) male connectors, designed for reliable RS232 connections between computers, peripherals and serial switchboxes. The grey cable features full 1:1 wiring for all 25 lines and enhanced shielding to reduce electromagnetic interference and data loss.

Advantages

The cable provides direct 1:1 connection of 25 lines, a screen line bonded to the cable foil shield and both connectors, and bronze contacts with gold plating for improved contact reliability. The connector housings are moulded with a special plastic to provide strain relief, and hand locking screws ensure secure mechanical connection.

Suitable for

• Connecting a switchbox to a computer
• Linking two devices with RS232 25‑pin interfaces
• Serial communication setups requiring long cable runs (up to 9 m)

How to use

Plug each DB25 male connector into the corresponding DB25 female port on your devices or switchbox, then tighten the hand screws by hand to secure the connection. Ensure both devices use RS232 signalling and compatible pinouts. Route the cable away from strong sources of electromagnetic noise and avoid sharp bends to maintain signal integrity.

Usage recommendations

For best performance, keep cable length appropriate for your RS232 setup (9 m maximum as supplied), avoid running the cable parallel to power lines, and check device pinouts before connecting to prevent communication errors.
