Description Return to top of page

Quatech's 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, Quatech's DSC-100 uses a four-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.)
