The 7205e low-profile PCI Express serial interface provides two serial ports configurable for RS-232, RS-422 or RS-485. Each serial port utilizes a 16C950 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 14.7456 oscillator and UART's flexible clock prescalar supports the widest range of standard and non-standard baud rates.

In RS-485 mode, the transmitter is automatically enabled in hardware, eliminating the need for application software control. This allows the 7205e to be used with standard serial communications applications and removes the risk of bus contention and data corruption. In RS-232 mode, all modem control signals are implemented for maximum compatibility with a wide range of serial peripherals.

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

The 7205e 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 7205eS. Both versions ship with a 36 inch cable that terminates to two DB9M connectors.
