PCI Express serial interface adapter

Sealevel Systems announces a new two-port PCI Express serial interface adapter with advanced UART architecture, the COMM+2.PCIe. The high-performance 16C950 UART includes 128-byte FIFOs, eight times larger than those found on comparable serial adapters, and provides error-free operation in high-speed serial applications. Additionally, the 16C950 UART supports 9-bit framing and is fully software compatible with legacy 16550 UART applications. The serial ports on the COMM+2.PCIe are individually configurable for RS-232, RS-422, or RS-485. The 14.7456 MHz oscillator and the UART’s flexible clock prescaler support the widest range of standard and non-standard baud rates. With this advanced architecture, each serial port is capable of data rates to 921.6K bps. In RS-485 mode, the transmitter is automatically enabled in hardware, eliminating the need for application software control. This allows the COMM+2.PCIe to be used with standard serial applications while removing the risk of bus contention and data corruption. In RS-232 mode, all modem control signals are implemented providing maximum compatibility with a variety of serial peripherals, such as PLC's, bar code readers, scales, and other data acquisition/control devices. All Sealevel PCI Express serial adapters include SeaCOM™ software for Windows 98, ME, 2000, NT, XP, Vista and Linux operating systems. As an added value, customers also receive WinSSD, a full-featured application for testing and diagnostics including BERT (Bit Error Rate Testing), throughput monitoring, loopback tests, and test pattern message transmissions. The COMM+2.PCIe is available immediately from stock priced at $289 for low profile (Item# 7205e) and standard size (Item# 7205eS) PCI Express slots. Both items include a cable with two DB-9M connectors. Standard operating temperature range for is 0 - +70°C (extended temperature versions operating from -40 - +85°C are available). Like all Sealevel I/O products, the COMM+2.PCIe is backed by a lifetime warranty. Sealevel Systems, founded in 1986, provides industrial computing solutions in addition to a variety of communications and I/O products including PCI Bus cards, Ethernet serial servers, USB serial adapters, PCMCIA cards, and PC/104 modules.
