7802e PCI Express serial interface adapter provides eight serial ports individually configurable for RS-422 or RS-485 communications. For error-free operation in high-speed serial applications, the board's high-performance 16C950 UART includes 128-byte FIFOs, eight times larger than those found on standard 16550 UARTs. 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.
