New PCI Express 2-Port RS-232 Serial Interface

Sealevel Systems announces the 7202e, a new low-profile two-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 instrumentation, barcode readers, and other data acquisition/control devices.

The 7202e’s high-performance 16C950 UART includes 128-byte FIFOs for error-free operation in high-speed serial applications. Additionally, the UART supports 9-bit framing and is fully software compatible with legacy 16550 UART applications. The board includes a 14.7456 MHz oscillator and provides a flexible clock prescaler to support the widest range of standard and non-standard baud rates up to 921.6K bps. The 7202e is PCI Express X1 compatible and will work in any PCI Express slot.

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 7202e ships with a 36-inch cable that terminates to two DB9M connectors. Standard operating temperature range is 0°C to 70°C (extended temperature versions operating from -40°C to 85°C are available). Like all Sealevel I/O products, the 7202e is backed by a lifetime warranty.
