Low Profile PCI was designed to provide greater flexibility for embedded systems, thin-clients, and desktop and server environments. The boards are mechanically similar to standard PCI boards, but use a shorter board and a different mounting bracket. They are designed to fit into systems as low as 3.350" without using riser cards. The boards are built on 32-bit addressing, and can be used in standard PCI backplanes or with specialized Low Profile PCI brackets.
The DSCLP-200/300 provides two independent serial ports to a host computer via a single Low Profile PCI slot. The boards are built using the smallest (MD1) Low Profile board specification, which allows them to be used in even the smallest size systems.
The boards also use a universal PCI connector compatible with both the 3.3V connector key required by the specification and the 5V connection used by older PC and thin client systems. This means that they can be used with current equipment, and will not need to be replaced as systems are upgraded.
Each port on the board can be configured as either RS-422 or RS-485 for full or half-duplex communication. It is implemented with an automatic RS-422/485 transmitter enable/disable function that permits the hardware itself to regulate data flow by only driving lines while actively transmitting--providing increased speed and convenience over the older software controlled method.
The channels are addressed in a continuous 16-byte I/O block for simplified software access. And, all channels may also share one PCI interrupt. An interrupt status register is available for determining the interrupt source. All PCI registers are properly implemented, and users can be assured that these boards will be good citizens on the PCI bus.
The boards are implemented with 16550 UARTs containing 16-byte FIFOs. They have a clock multiplying feature allowing them to achieve data rates as high as 460.8 kbps. The high clock speeds and deep FIFOs will greatly reduce CPU overhead, making these boards an ideal choice for heavy multi-tasking environments.
The DSCLP-200/300 comes with a cable providing two DB-9 ports. Windows 95/98/Me/NT/2000/XP and OS/2 are supported. |
