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. Click “OK”. 3-8 Quatech Inc.[...]

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”. . 3-9 Quatech Inc.[...]

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. 3-11 Quatech Inc.[...]

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. 3-14 Quatech Inc.[...]

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. The "Add New Hardware Wizard" utility in Windows 95 was designed to add new hardware and up[...]

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. If no INF files are found, click the “Browse” or “O[...]

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. 1. Double click the “System” icon inside th[...]

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. If the “A utomatic Settings” option is selected, it will hav[...]

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. 3-19 Quatech Inc.[...]

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" positi[...]

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. 03E8 hex COM3 Factory default for Serial 1. 02F8 hex COM[...]

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. To select a different IRQ, move the jumper to the appropriate positio[...]

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. In either case, the software driving [...]

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). Generally, data terminal equipment is defined as the communication source and data communication equipment is defined as the device that provides a communication channel between two DTE-type[...]

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. J5 is used for Serial 0 and J6 is used for Serial 1. The DTE/DCE sel[...]

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. The standard serial port connections are listed in Figure 14 . 22 9 22 9 Ring Indicator (RI) 4 7 5 8 Clear To Send (CTS) 5 8 4 7 Request To Send (RTS) 20 4 6 6 Data Set Ready (DSR) 7 5 7 5 S[...]
