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. As an enhanced serial adapter, the DSC-100 has a special clock-multiplying feature that will allow it to reach data rates as high as 921.6 kbps--a
significant improvement over legacy serial boards with a maximum data rate of 115.2 kbps. The standard DSC-100 is implemented with 16550 UARTs containing 16-byte FIFOs which reduce processing overhead and allow data rates to 230.4 kbps. The optional upgrade to 16750 UARTs containing 64-byte FIFOs (DSC-100-750) will increase board speed to 921.6 kbps. This upgrade is recommended for heavy multi-tasking environments, and for
applications involving high data rates.
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, which is only available for the standard board, 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.
Drivers are included for installing the DSC-100 under OS/2.
