Serial cable assemblies are used for data transfers between computers via serial communication protocols (data sent one bit at a time). Serial cable assemblies mostly use the RS-232 (Recommended Standard 232) interface specifications.
Although serial cable assemblies have been replaced in some areas by Ethernet, wireless and USB connectorstechnologies, they are still used in applications where two devices need to connect with each other by means of serial communication protocols.
Industry examples include industrial automation systems, scientific instruments, point of sale technologies, consumer products and industrial circuit boards.
The main types of serial cable assemblies include:
