The 7406e low profile PCI Express serial interface provides four 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 a 16C954 UART 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 7406e is a PCI Express X1 board compatible with any low profile PCI Express slot. If you have a standard size PCI Express slot, order the 7406eS
. Both versions ship with a 36 inch cable that terminates to four DB25M connectors.
