 Description Return to top of page

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 SSCLP-100 provides one RS-232 serial port 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.

All PCI registers on the SSCLP-100 are properly implemented. Thus, users can be assured that Quatech boards will be good citizens on the PCI bus, and will not cause conflicts with other properly configured devices.

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 SSCLP-100 uses a single on-board D9 serial port. Windows 95/98/Me/NT/2000 and OS/2 are supported.
