COMPAQ DC195A

The PCI Serial and Parallel I/O Card is designed and tested specifically for the d530 Ultra-Slim Desktop providing serial and parallel ports for connectivity to external devices.

The PCI Serial and Parallel I/O Card is a PCI-based card which provides both a parallel and serial IO port that can be used simultaneously to connect to external devices such as a printer, scanner and/or a modem. The card is a dual function device, offering IO or memory mapped access to an ultra-high performance Universal Asynchronous Receiver Transmitters (UARTs). The UART channel is the fastest available PC-compatible UART, offering data rates up to 15Mbps and 128-byte deep transmitter and receiver FIFOs. The dual FIFO's reduce CPU overhead and allow utilization of higher data rates.

The parallel port is an IEEE 1284 compliant SPP, EPP and ECP parallel port that fully supports the existing Centronics interface. For legacy applications, the PCI resources have been arranged so that the parallel port can be located at standard I/O addresses.

The serial port is a standard 9-pin D-connector supporting baud rates up to 920Kbps.
