Converters
change signals from one physical system to another.
Example: An RS 232 V.24 signal is converted to a TTY 20mA signal. The transmitted data is not affected.
Connectors
are used for connecting devices or expansion components to the power supply, data cables or I/O devices.
Adapters
can modify the pinning, as well as the output direction of a connector attached to the core product. It is also possible to implement transitions from “n”-pin” to “x”-pin.
