===== Passive Converter =====

A **passive converter** refers to a simple device designed to merely change the port of a keyboard's cable. This **excludes** the translation of the keyboard's protocol, which is a task usually done by an [[active converter]] instead.

Thanks to their simplicity, passive converters are often more affordable than active converters, but their practical uses can be very limited.

==== Use-cases ====
=== AT-to-PS/2 ===

Although backwards compatibility is rare among protocols, the PS/2 protocol stands out as a prevalent example as it can interpret an AT keyboard. Furthermore, an active PS/2-to-USB converter can be used afterwards to practically convert an AT keyboard into USB.
