Sealevel Systems' 7802e PCI Express serial interface adapter that has eight serial ports for RS-422 or RS-485 communications and has software that supports Windows and Linux operating systems. Courtesy: SealevelSealevel Systems' 7802e is a PCI Express serial interface adapter that provides eight serial ports individually configurable for RS422 or RS485 communications. For error-free operation in high-speed serial applications, the board's 16C950 UART includes 128-byte FIFOs. Additionally, the 16C950 UART supports 9-bit framing and is fully software compatible with legacy UART applications. The 7802e is ideal for a variety of applications including test and measurement, security systems, and broadcast.

The 7802e 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. In RS485 mode, the transmitter is automatically enabled in hardware, eliminating the need for application software control. This allows the 7802e to be used with standard serial applications while removing the risk of bus contention and data corruption.

The Sealevel PCI Express serial adapters include SeaCOM software for Windows and Linux operating systems. They also come with WinSSD, a full-featured application for testing and diagnostics including BERT (Bit Error Rate Testing), throughput monitoring, loopback tests, and test pattern message transmissions.
