RS232 Serial Port Cable: Female DB9 to Female DB9 Cross-Over Connection 1.5 Metres
This RS232 serial port cable provides a direct cross-over connection between two devices equipped with female DB9 serial ports. With its 1.5-metre length and cross-over wiring configuration, it eliminates the need for additional null modem adapters when connecting PCs to other PCs, industrial control equipment, or legacy peripherals that utilise standard RS232 communication protocols. The cable is designed for straightforward data transfer, terminal communication, and device control applications where a direct serial link is required between compatible hardware.
Features and Construction
The cable features practical design elements suitable for basic serial communication needs in both home and technical environments.
Material and Build
The cable utilises a milky white PVC outer jacket that provides basic insulation and clear visual identification in technical setups. This colouring helps distinguish it from power cables and other connection types, reducing confusion in multi-cable installations. The construction includes standard copper conductors suitable for RS232 signal transmission at typical serial communication speeds.
Size and Practical Fit
At 1.5 metres in length, this cable offers sufficient reach for connecting adjacent equipment on a desk, workbench, or within a small technical enclosure. This length accommodates typical PC-to-PC or PC-to-peripheral configurations while maintaining manageable cable routing and avoiding excessive slack that can create clutter in workspace environments.
Uses and Placement
The cable serves specific applications where direct serial communication between compatible devices is necessary.
Event or Professional Use
In professional environments, this cable enables direct connections between computers for data transfer, terminal sessions, or file sharing via serial protocols. It's suitable for linking industrial control systems, laboratory equipment, point-of-sale terminals, or other legacy hardware that maintains DB9 serial interfaces for configuration or data retrieval purposes.
Everyday Home Use
For home users with older peripherals or hobbyist projects, this cable provides connectivity between PCs and devices like older printers, modems, GPS units, or microcontroller development boards that utilise DB9 serial interfaces. The cross-over wiring allows direct communication without requiring additional adapters or gender changers.
Benefits and Buying Value
The cable offers practical advantages for users requiring basic serial connectivity between compatible devices.
Reuse and Low Maintenance
As a straightforward connection cable with standard DB9 connectors, it can be reused across multiple projects and applications that share the same interface requirements. The PVC jacket provides basic protection against everyday wear, while the standard connectors ensure compatibility with a wide range of existing serial port hardware without requiring specialised maintenance.
Why Choose This Product
This cable provides a complete cross-over solution in a single cable, saving users from purchasing separate cables and null modem adapters. The 1.5-metre length represents a practical middle ground between too short and excessively long cables for typical desktop or workstation setups. The female-to-female configuration directly matches common port types on computers and many peripheral devices.
