Sealevel 7803ec

7803ec COMM+8.PCIe Low Profile PCI Express 8-Port RS-232 Serial Interface

Description

The 7803e low-profile PCI Express serial interface provides eight RS-232 serial ports. For maximum compatibility with a wide range of peripherals, the board supports all standard RS-232 modem control signals. The serial ports utilize 16C954 UARTs with 128-byte Tx/Rx FIFOs that enables data rates to 921.6K bps for reliable high-speed communications in data intensive applications. This high-performance UART includes 9-bit framing support and is fully software compatible with legacy 16550 applications. In addition, the board derives a 62.5 MHz clock from the PCI Express link. This ultra-high speed clock is divided by a flexible 8-bit clock prescalar with 1/8 steps to provide support for the widest range of standard and non-standard baud rates.

The Sealevel SeaCOM software driver and utilities make installation and operation easy using Microsoft Windows and Linux operating systems.

The 7803e 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 a 36 inch cable that terminates to eight DB25M connectors.
