Serial UPCI Board, 2-Port, DB-9, Surge - DSCLP-200/300IND

The Quatech, Inc. DSCLP-200/300(two-port) and SSCLP-200/300 (one-port) provides upto provides two RS-422 or RS-485 asynchronous serial communication interfaces for IBM-compatible personal computer systems using the PCI expansion bus. The DSCLP-200/300 uses Quatech's new Enhanced Serial Adapter design. Legacy serial port data rates are limited to a maximum of 115,200 bits per second. Quatech Enhanced Serial Adapters can achieve data rates as high as 460,800 bits per second. This discussion relates to DSCLP-200/300. A SSCLP-200/300 is just one port in the discussion. As a PCI device, the DSCLP-200/300 requires no hardware configuration. The card is automatically configured by the computer's BIOS or operating system. The two serial ports share a single interrupt line and are addressed in a contiguous block of 16 bytes. A special interrupt status register is provided to help software to manage the shared interrupt.

The DSCLP-200/300's serial ports are implemented using 16550 Universal Asynchronous Receiver/Transmitters (UARTs). These UARTs contain hardware buffers (FIFOs) which reduce processing overhead and allow higher data rates to be achieved. The 16550 contains a 16-byte FIFO and can transmit and receive data at a rate of up to 230,400 bits per second.

The "IND" option provides the protection essential for reliable use in an industrial environment.
