The 7106e low-profile PCI Express serial interface from Sealevel Systems offers a single serial port configurable for RS-232, RS-422, RS-485 or RS-530.
The ultra high-speed UART, flexible clock prescalar, and large 256-byte Tx/Rx FIFOs allow the adapter to support the widest range of standard and non-standard baud rates exceeding 921.6 Kbps. These features make the unit suitable for data intensive applications that require reliable, ultra-fast throughput rates. The electrical interface, echo suppression and line termination are set via convenient on-board DIP switches, which can be overridden in software. The board's software selectable Slew Rate Limiting feature minimizes electromagnetic interference where high baud rates are not required. For rapid troubleshooting, on-board LEDs display the board heartbeat, electrical interface selection and line termination state. In RS-485 mode, the transmitter is automatically enabled in hardware, eliminating the need for application software control. This allows the adapter to be used with standard serial communications applications and removes the risk of bus contention and data corruption. In RS-232 mode, all modem control signals are implemented for maximum compatibility with a wide range of serial peripherals. The company's SeaCOM software driver and utilities make installation and operation easy using Microsoft Windows or Linux operating systems.
