RS232 Cable ROLINE DB9 M - M 1.8 m

The ROLINE RS232 Cable DB9 M - M 1.8 m is a serial data cable with two 9‑pin D‑Sub (DB9) male connectors, designed for reliable 1:1 signal transmission between RS‑232 devices. The 1.8 m grey cable is suitable for connecting equipment such as computers, modems, serial printers or a switchbox using the IBM AT style serial interface. The cable's screen conductor is connected to the foil shield and to both connectors to provide basic shielding.

Advantages

This DB9 M‑M cable provides straight‑through wiring with all pins connected 1:1, ensuring compatibility with devices that expect standard RS‑232 pinouts. The integrated foil screen tied to both connectors helps reduce interference. With male DB9 connectors on both ends and a 1.8 m length, the cable offers straightforward, flexible connections between serial devices.

Suitable for

• Connecting computers or terminals to modems and serial printers
• Linking devices to a serial switchbox or serial port switch
• Establishing direct RS‑232 links between industrial or laboratory equipment

How to use

Connect each DB9 male connector to the corresponding female DB9 serial port on the devices you want to link. Ensure connectors are seated firmly and screws (if present) are tightened to secure the connection. Use typical RS‑232 settings (baud rate, parity, data bits, stop bits) configured in the connected devices' software or firmware to establish serial communication.

Usage recommendations

For reliable operation keep cable runs away from strong sources of electromagnetic interference and avoid sharp bends. Verify device pinouts when connecting legacy equipment; this straight‑through cable assumes standard RS‑232 wiring on both ends.
