Description
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 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.
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.

CONNECTOR:
The DSCLP-100 has an
on-board D25 connector, the included cable provides two D9 male
serial ports. Each D9 male serial port has the following pinout:
|
Pinout:
PIN 1: Carrier Detect
PIN 2: Data Input
PIN 3: Data Output
PIN 4: Data Terminal Ready
PIN 5: Signal Ground
PIN 6: Data Set Ready
PIN 7: Request To Send
PIN 8: Clear To Send
PIN 9: Ring Indicator |

OS SUPPORT:
Windows 95/98/NT/2000 and OS/2.
CONFIGURATION: Windows does not
assign COM1-COM4 to ports addressed at nonstandard locations.
Therefore, the DSCLP will install in the lowest available address
block over COM4.
