More information

The Sealevel 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 prescalar, 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 is a PCI Express X1 board compatible with any low profile PCI Express slot. If you have a standard size PCI Express 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.
