The 7205eS 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 which 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 prescaler 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 7205eS 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 Windows 98, ME, 2000, NT, XP, Vista and Linux operating systems.

The 7205eS is a PCI Express X1 board compatible with any PCI Express slot. The 7205eS is for use in standard size PCI Express slots. If you have a low profile PCI Express slot, order the 7205e. The board ships with a 36" cable that terminates to two DB9M connectors.
