The 7204e low-profile PCI Express serial interface provides two serial ports configurable for 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 7204e to be used with standard serial communications applications and removes the risk of bus contention and data corruption. The Sealevel SeaCOM software driver and utilities make installation and operation easy using Microsoft Windows and Linux operating systems. The 7204e 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 7204eS. Both versions ship with a 36 inch cable that terminates to two DB9M connectors.

Spurious error messages, especially those from rolling-stock subsystems, can be difficult and time consuming to diagnose. Siemens Rail, in Manchester, wished to install a data logging system onto their rolling stock to transmit data in real-time back to their depot for efficient data analysis by their team.
