Applications

PS/2-to-serial adapter cables like this one were used to interface PS/2 keyboards with older systems and devices that accepted keyboard input over a DB9 serial port rather than a standard PS/2 socket. This type of adapter saw use with legacy industrial terminals, PLCs, embedded systems, and specialized computing equipment from the late 1980s through the 1990s that accepted keyboard input via serial. They also appear in console and KVM setups where a serial keyboard protocol was required. While modern computers have largely moved to USB, these adapters remain useful for maintaining or servicing legacy hardware that still relies on serial keyboard interfaces.
