PCI-E to Dual PS/2 Expansion Adapter Card with MCS9990 Chip, PCIe X1 PS2 Round Port Extender for Traditional PS/2 Keyboard & Mouse, Plug-and-Play Driver-Free Design, Internal Desktop PCI Express Expan

This PCI-E to PS/2 expansion card adopts mature MCS9990 master control chip, which converts PCIe bus signal into two independent PS/2 round ports, perfectly supporting traditional PS/2 interface keyboards and mice that lack USB conversion function.

It adopts universal PCIe X1 slot design, compatible with PCIe X4/X8/X16 slots of all ATX and MATX motherboards. The built-in dual PS/2 ports can connect keyboard and mouse separately without signal conflict or input delay.

No complicated driver setup is required after installation; the card can be automatically recognized by all mainstream Windows operating systems. It comes with a standard full-height metal baffle and supports low-profile replacement for mini chassis.

Suitable for industrial control hosts, POS cash registers, old monitoring equipment and industrial computers that rely on PS/2 input devices, solving the compatibility problem of new motherboards canceling native PS/2 interfaces.
