The DSC-100 enhanced serial board provides two RS-232 serial ports on a single
PCI board. As a PCI device, the DSC-100 requires no hardware configuration.
The card is automatically configured by the computer's BIOS or operating system.
The two serial ports share a single interrupt line and are addressed in a contiguous
block of 16 bytes. A special interrupt status register is provided to manage
the shared interrupt. The DSC-100 completely adheres to the PCI 2.1 specification,
and all PCI registers are properly implemented, so users can be assured that
the DSC-100 will not conflict with other properly implemented PCI devices.
The DSC-100 is implemented with two 16750 UARTs containing 64-byte FIFOs. It
has a clock multiplying feature allowing the board to achieve data rates as
high as 921.6 kbps. The high clock speeds and deep FIFOs will greatly reduce
CPU overhead, making the DSC-100 an ideal choice for heavy multi-tasking environments.
To maintain maximum signal integrity, the DSC-100 uses a 4-layer board design.
But, for even more protection in industrial environments, an optional surge
suppression package is available. This "IND" option, applies a surge suppressor
to each line that is capable of sustaining up to 40A 20ms peak transient surges,
a clamping voltage of 30V and a peak energy dissipation of 0.1 Joules. (Note
that implementing the IND option restricts the board's speed to 115.2 kbps.) Low Level Output: -5V max, -8V typical
Switching Speed(low to high): 1.4 µs with 2500 pF load 40 ns with 15 pF

OS SUPPORT:
Windows 95/98/NT/2000 and OS/2.
CONFIGURATION: Windows does not assign COM1-COM4 to ports addressed
at nonstandard locations. The DSC-100 will install in the lowest available address
block over COM4. For example, COM 5-6, COM 6-7, etc.
