Serial Cables

A serial cable is a computer cable used for data transfer and information between computers. The cables achieve this via serial communication protocols (data sent one bit at a time). Serial cable assemblies mostly use the RS-232 (Recommended Standard 232) interface specifications.

RS offer a selection of high-quality serial cables from leading brands including Phoenix Contact, Startech, Molex, TE Connectivity and of course RS PRO.

How is a RS 232 Cable made?

RS232 cables are typically made from shielded cable and will be terminated with D-subminiature connectors. D-subminiature connectors could be DB9 (9-pin) or DB25 (25-pin). The connectors can be plugs (male) or sockets (female). Cable ends often incorporate strain relief for added flexibility.

What are serial cables used for?

Although serial cables have been replaced in some areas by Ethernet, wireless and USB connectors technologies, they are still used in some applications. The cable assemblies are used for connecting computers to printers, PLCs to HMIs, input, and output modules and even motor drives. With the help of adapters, it is still possible for devices to communicate with each other using old and new standards.

Industry examples include industrial automation systems, scientific instruments, point of sale technologies, consumer products and industrial circuit boards.

What are the different types of assemblies?

Basic DTE-DCE cables with universal compatibility features, typically used in data terminal equipment and data communication applications. Null modem cables, which ensure connection stability between two PCs where no modem is present. V.35 crossover cables, which enable enhanced data rates and increased transfer speeds. Serial printer cables are used to connect computers and printers with serial port features.
