The QSC-200/300 provides 4 independent serial channels, each of which is jumper configurable for either RS-422 or RS-485. All 4 channels are addressed in a continuous 32-byte I/O block for simplified software access, and all channels can share one PCI interrupt. An interrupt status register is available for determining the interrupt source. PCI registers are properly implemented to assure that Plug & Play works reliably, and that the card will not cause PCI bus conflicts.
The QSC-200/300 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 QSC-200/300 an ideal choice for heavy multi-tasking environments.
To maintain maximum signal integrity, the QSC-200/300 uses a 4-layer board design. For even more protection in industrial environments, an optional surge suppression package is available for the standard board. 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.)
External connections are provided via one female D-37 connector. Optional cables will convert the D-37 into 4 standard D-25 male or 4 standard D-9 male connectors. Support is provided for Windows 95/98/NT/2000/XP and OS/2. |
