PCI 2.3, RS-232, 2 x DB-9 (M)
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. Quatech's DSCLP-100 provides two independent RS-232 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 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 Quatech 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-100 comes with a cable providing two D9 ports. Windows 95/98/Me/NT/2000 and OS/2 are supported.
