Page 7: General Information
IRQ2 to IRQ7, IRQ10 to IRQ12, IRQ14, or IRQ15. (Early versions of the QS-100D are limited to IRQ2-7.) All four ports on the QS-100D can share one interrupt level. A special interrupt status register is provided to allow controlling software to manage the shared interrupt level.
Page 8 1.1.2 UART Upgrade The UART upgrade on the QS-100D750 and QS-100IND750 boards provides a 16750 UART in place of the 16550 UART found on the standard QS-100D. The UART (Universal Asynchronous Transmiter and Receiver) takes byte size data from the bus side of board and breaks it into the bit size data required for serial communication.

Page 11: Hardware Installation
2.1 and 2.2 of this document for detailed information on how to set the address and IRQ level. 2. Turn off the power of the computer system in which the QS-100D is to be installed. 3. Remove the system cover according to the instructions provided by the computer manufacturer.
Page 12: Setting The Base Address
2.1 Setting the Base Address The base address of the QS-100D is set using the 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.
Page 13 Position 6 of SW2 is used to enable or disable the interrupt status register. Factory default setting --- 0300 hex (no digits) Another Example --- 54A0 hex (no digits) Figure 5 --- Serial Port base I/O address selection switches QS-100D User's Manual Get other manuals https://www.bkmanuals.com...
Page 14: Setting The Interrupt Level (Irq)
2.2 Setting the Interrupt Level (IRQ) The QS-100D allows the use of any interrupt level in the range IRQ2 to IRQ7, IRQ10 to IRQ12, IRQ14, or IRQ15, selected using jumper pack J6. (Early versions of the QS-100D are limited to IRQ2-7.) In Figure 6, the factory default setting of IRQ3 is shown.
Page 15: Interrupt Status Register
QS-100D will be unable to signal subsequent interrupts. If the QS-100D is of revision level 'C' or higher, an I/O write to the interrupt status register will cause another hardware interrupt to be generated if the interrupt status register is non-zero.

Windows 95 environment . Also a custom Windows 95 serial device driver is included with the QS-100D to support the use of the 16750 UART’s 64 byte fifo. Windows 95 uses the “INF” file to determine the system...
Page 18 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.

3. Double click the device group “Multi-function Adapters”. The QS-100D model name should appear in the list of Multi-function adapters. 4. Double click the QS-100D model name and a properties box should open for the hardware adapter. 5. Click the “Resources” tab located along the top of the properties box.
Page 20 Click “OK” to save your changes, or “Cancel” to abort. 7. The QS-100D serial ports are also listed under the group Ports (Com and LPT). Windows 95 does not assign COM1 - COM4 to ports addressed at nonstandard locations.

Page 27: Troubleshooting
Any unauthorized repairs or modifications will void the QS-100D's warranty. Computer will not boot up. 1. Is the QS-100D properly inserted? Remove the card and try again. Perhaps try a different expansion slot. 2. Is the base address correctly set? Check for address conflicts with other devices in the system.
