    0008 hex intervals. Available interrupt levels include IRQ2 to IRQ7, IRQ10 to IRQ12, IRQ14, or IRQ15. Both ports on the DS-100 can share one interrupt level or an interrupt level can be shared with another Quatech adapter that supports interrupt sharing. The shared interrupt feature minimizes the system resources consumed by the adapter.

    Windows 95 environment . Also, a custom Windows 95 serial device driver is included with the DS-100 to support the use of the FIFOs on the 16550 UARTs. Windows 95 uses the “INF” file to determine the system resources required by the DS-100, searches for available resources to fill the requirements of the board, and then updates the hardware registry with an entry that allocates these resources.
  • Page 25 6. An Install From Disk dialog box should pop up. Insert the diskette with the Quatech INF files on it, select the correct drive letter, and click the “OK” button. Windows 95 automatically browses the root directory for an INF file that defines configurations for Multi-function Adapters.

    5. Addressing Ports 5.1 Setting the address The base address of each port of the DS-100 is set using two DIP switch packs. When setting the address selection switches, a switch in the "ON" position specifies that the corresponding address line must be a logic 0 for the port to be selected. Similarly, a switch in the "OFF"...

  • Page 33: Interrupt Level (Irq)

    6. Interrupt Level (IRQ) The DS-100 allows the use of any interrupt level in the range IRQ2 to IRQ7, IRQ10 to IRQ12, IRQ14, or IRQ15, selected using jumper block J3 (for Serial 0) or J4 (for Serial 1). In Figure 9, the factory default settings for Serial 0 and Serial 1 are shown.

  • Page 34: Interrupt Sharing

    6.1 Interrupt Sharing Both ports on the DS-100 can share the same interrupt level or they can share their interrupt with another Quatech adapter supporting sharable interrupts. Jumper J2 can be used to connect the UART generated interrupt directly to the selected IRQ or to enable the interrupt sharing circuit.
