Black Box Serial Host Adapter serial adapter - 4 ports

Adding device ports to your PC has never been easier. This Serial Adapter provides the PC with four RS-232 asynchronous ports. You can connect any device that uses the RS-232 electrical interface, such as modems, data-entry terminals, and plotters, to the Adapter. The Adapter is easy to set up and use. It can be installed in any of the PCI expansion slots on your PC. There's only one jumper to set. And the Adapter employs a unique clocking option that allows the end user to select one of three clocking modes to set the baud rate via the jumper. Because the Adapter works with many versions of Windows, it functions with the operating system you're already running. In a typical application, you can connect a modem, an async printer, a plotter, and a data-entry terminal all to one PCI slot of a single PC via the Adapter. This Adapter uses 16854 UART communication chip.
