Single Serial Port Supports Wide Range of Baud Rates

Description

7106e low-profile PCI Express serial interface, configurable for RS-232, RS-422, RS-485 or RS-530, include an ultra high-speed UART, flexible clock prescalar, and large 256-byte Tx/Rx FIFOs to allow the adapter to support the widest range of standard and non-standard baud rates exceeding 921.6 K bps.

The single serial port ideal for data intensive applications also includes an electrical interface selection via on-board DIP switch with software override. Electromagnetic interference is minimized by  software selectable Slew Rate Limiting. For rapid troubleshooting, on-board LEDs display the board heartbeat, electrical interface selection and line termination state.
