Black Box 2-port 16750 UART RS-232 Low-Profile PCI Card

The Serial Host Adapter provides multiple PCI-bus links for communication servers, point-of-sale (POS) systems, and other data-collection devices. Integration problems are a thing of the past with this Adapter, since it supports all PCI interrupts, giving you more IRQs to choose from when installing.

This card has 16750 UART (Universal Asynchronous Receiver/ Transmitters) chips, which are integrated circuits that convert bytes from the computer bus into serial bits for transmission.
