The Single-Port PCI Cards (PCI"RS-232/422/485/530) provide you with a single field-selectable port for your PC. These cards can easily be configured as RS-232, -422, -485, or -530, supporting asynchronous data rates up to 460.8 kbps. Choose the IC074C-R2 and get isochronous data rates up to the speed of the supplied clock. Want to connect over a clocked digital line while using your standard communications software? These cards let you do just that - without the need for expensive custom software. And, because these cards slide into any standard PCI slot, you won't have to deal with a cumbersome data-conversion box. They're ideal for field use! Configure the port as RS-232 for standard serial COM-port requirements, and you can use a card for modems, printers, plotters, and similar devices. Or you can select the RS-485/422 mode and go beyond the RS-232 cable limit - up to 5000 ft.! Use RS-422 mode for long-distance device connections that require noise immunity and high data integrity, such as in industrial automation and control applications. Or select RS-485 and capture data from multiple peripherals in an RS-485 multi-drop network, that is, a communications link between multiple locations using multiple local exchange carriers. Up to 31 RS-485 devices can be connected to each port to automate your data collection. In both RS-232 and -422 modes, the PCI cards work seamlessly with your standard operating system's serial driver. In RS-485 mode, the cards' special auto-enable feature allows the RS-485 ports to be viewed by the operating system as a COM port. This allows you to use a standard COM driver (instead of a custom software driver) for your high-speed RS-485 connections. It also makes the cards compatible with DOS, and Windows 3.1x/95/98 or Windows NT.
