The 7803ec low-profile PCI Express serial interface provides eight RS-232 serial ports. All modem control signals are implemented for maximum compatibility with a wide range of serial peripherals. Each serial port features an ultra high-speed UART, flexible clock prescaler, and large 256-byte Tx/Rx FIFOs allowing the adapter to support the widest range of standard and non-standard baud rates to 230.4 Kbps. These features make the 7803ec 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 7803ec PCI Express X1 board is compatible with any low profile PCI Express slot. A standard profile bracket is also included. The board includes your choice of 36-inch spider-cable that terminates to eight DB25M (CA202) or DB9M (CA231) connectors.
