Low Profile PCI 8-Port RS-232 Serial Interface The 7803c low-profile PCI serial interface provides eight RS-232 serial ports capable of data rates up to 230.4 Kbps. Each RS-232 port implements all modem control signals for maximum compatibility with a wide range of serial peripherals. The 7803c utilizes eight, independent, enhanced 16550 compatible UARTs that provide 256-byte Tx/Rx FIFOs allowing the adapter to support a wide range of non-standard baud rates. These features make the 7803c ideal for data-intensive applications that require reliable, fast throughput rates. The Sealevel SeaCOM software driver and utilities make installation and operation easy using Microsoft Windows operating systems. The 7803c is a PCI board compatible with any low profile PCI slot. If you have a standard size PCI slot, be sure to select the standard profile bracket. The board includes your choice of 36-inch spider-cable that terminates to eight DB25M (CA202) or DB9M (CA231) connectors. Part: 7803c | Model: COMM+8.LPCI WORLD CLASS. AMERICAN MADE.
