1. General Information The Quatech, Inc. DS-100 provides two RS-232 asynchronous serial communication interfaces for IBM-compatible personal computer systems using the 16-bit ISA (Industry Standard Architecture) expansion bus. The DS-100's serial ports are implemented using 16550 Universal Asynchronous Receiver/Transmitters (UARTs).

3. Windows 2000 Configuration Windows 2000 maintains a registry of all known hardware installed in the computer. Inside the hardware registry Windows 2000 keeps track of all of the system resources, such as I/O locations, IRQ levels, and DMA channels.
2. Double click on the “Add New Hardware” icon. 3-2 Quatech Inc..
3. The next window will be the “Welcome to the Hardware Wizard”, click “Next”. 4. Next choose the “Add/Troublshoot a device” radio button, click “Next”.

7. Next select “Ports (COM & LPT)”, click “Next”. 3-7 Quatech Inc..
8. In the next window under manufac ture select “(Standard port types), and under Models select “Communications Port. Because Windows will not detect plug and play you will have to manually enter the settings.
9. Next you will have to change the “Input/Output Range” to a setting that is not in use “No conflicts” by choosing a different “Basic Configuration”.
10. The “Input Request” (IRQ) must be set to corresponds with the jumpers setting on the DS-100 board. 3-10 Quatech Inc..
Once you have chosen the IRQ that corresponds with the setting on the Quatech DS-100 card the window will display “no conflicts” and the red circle with a slash of the “Input/Output Range” will not be present.
11. Next Windows will begin the install the hardware, click “Next”. 3-12 Quatech Inc..
12. Next the “Completing the Add/Remove Hardware Wizard” will appear, click “Finish”. 3-13 Quatech Inc..
13. Next Windows will prompt you to restart the computer so the changes will take effect and show the new ports. Select “No” to install the second port. Repeat the same process to install the second channel. Finally, in order for the changes to take effect you will have to restart the computer.
4. Windows 95 Configuration Windows 95 maintains a registry of all known hardware installed in your computer. Inside this hardware registry Windows 95 keeps track of all of your system resources, such as I/O locations, IRQ levels, and DMA channels.
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.
4.2 Viewing and Changing Resources with Device Manager The following instructions provide step-by-step instructions on viewing and changing resources of the DS-100 in Windows 95 using the “Device Manager” utility. Select Start|Help from within Windows 95 for additional information on this utility.
5. Click the “Resources” tab located along the top of the properties box. Confirm that the resources Windows 95 has allocated for the D S-100 match the hardware configuration. To modify any of the resource settings click the resource name and click the “Change Setting” button.
10. Use the Logical COM Ports numbers to access the serial ports on your D S-100 through your software applications. Note: The Logical COM Port name is assigned to your ports by Windows 95. This name is required by a Windows 95 application when accessing a particular port.

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.
Switch on bit = 0 Switch off bit = 1 Serial 0 uses SW1 and SW2 Serial 1 uses SW3 and SW4 ON 123456 78 8 82 1 F 4 8 123456 ON 02 1 3 0 00 0 0 0 SW 1 SW 2 enable/disable ON 123456 78 8 82 1 F 4 8 123456.
The standard addresses for serial ports COM1 and COM2 are listed in Figure 7. Recommended addresses for serial ports COM3 and COM4 are also listed. The switch settings for these addresses are shown in Figure 6. 02E8 hex COM4 Recommendations only. No official standards exist for COM3 and COM4.
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.
6.1 Interrupt Sharing Both ports on the DS-100 can share the same interrupt leve l 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.
7. Exter nal Connections EIA/TIA -232-E devices are classified by their function as either Data Terminal Equipment (DTE) or Data Communication Equipment (DCE).
To simplify connections to other devices, each port on the DS-100 is equipped with a jumper block that allows the port to be configured as either a DTE- or DCE-type device. This allows the DS-100 to communicate with either DTE- or DCE-type devices without using a null modem cable.
The DS-100 connects to peripheral equipment through male D-9 connectors. Adapters are available to convert these connectors into standard D-25 male connectors.
