Liberty, SC, USA - December 05, 2013 --

Product Features

Eight RS-232 Ports with all Modem Control Signals
Fully compliant with all PCI Express X1 slots
Powerful 16C954 UARTs provide 128-byte FIFOs
Oscillator and clock prescalar support wide range of baud rates
Supports 9-bit protocol framing and data rates to 921.6K bps
Included 36" cable terminates to eight DB25M or eight DB9M connectors
Supported in Microsoft Windows and Linux operating systems

Sealevel Systems announces the 7803e, a new low-profile eight port RS-232 PCI Express serial interface adapter with advanced UART architecture. For maximum compatibility with a wide range of serial peripherals, the board supports all RS-232 modem control signals making it a perfect solution for interfacing to a wide range of peripherals.

The 7803e's serial ports utilize 16C954 UARTs 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 board 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.

All Sealevel PCI Express serial adapters include SeaCOM software for Windows and Linux operating systems. For easy installation and troubleshooting, 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 7803e is available immediately from stock priced at $449 for low-profile (Item# 7803e) and full-height (Item# 7803eS) PCI Express slots. Both items ship with a 36 inch cable that terminates to eight DB25M connectors. Both boards are also available with a 36 inch cable that includes eight DB9M connectors. Standard operating temperature range is 0 - +70°C (extended temperature versions operating from -40°C - +85°C are available). Like all Sealevel I/O products, the 7803e is backed by a lifetime warranty.
