1 General Information The Quatech, Inc. DSCLP-100 (two-port) and SSCLP-100 (one-port) provide RS-232 asynchronous serial communication interfaces for Low Profile I BM-compatible personal computer systems using the PCI expansion bus. The DSCLP-100 uses Quatech's new Enhanced Serial Adapter design.
2 Hardware Configuration The DSCLP-100 is automatically configured at boot time by the computer's BIOS or operating system. There are no required switches or jumpers to set for installation. This chapter lists a number of optional jumper settings that control various hardware features.
2.3 Force High-Speed UART Clock (X2 or X 4 , J4-J5) These jumpers force an increase of the UART input clock frequency by a factor of two or four. This feature can allow legacy software to use baud rates above 115,200 bits per second.
3 Hardware Installation 1. Turn off the power of the computer system in which the DSCLP-100 is to be installed. 2. Remove the system cover according to the instructions provided by the computer manufacturer. 3. Make any desired optional jumper setting changes.
4 Address Map and Special Registers This chapter explains how the two UARTs and special registers are addressed, as well as the layout of those registers.
4.2 Enabling the Special Registers The DSCLP-100 contains two unique registers, an Interrupt Status Register and an Options Register. These registers are enabled when the SPAD jumper (J2) is removed (factory default). They replace the UART Scratchpad Register on accesses to register address 7.
4.4 Options Register The Options Register allows software to identify the DSCLP-100 as a Quatech Enhanced Serial Adapter. It also allows software to set the UART clock rate multiplier. Figure 9 shows the structure of the Options Register. The powerup default of the Options Register is all bits zero.
4.4.2 Clock Rate Multiplier A standard RS-232 serial port operates at a clock speed of 1.8432 MHz. In order to achieve higher data rates, Quatech Enhanced Serial Adapters can operate at two times, four times or even eight times this standard clock speed.
5 Windows Configurations 5.1 Windows Mille nnium 1. After inserting the DSCLP-100 for the first time the "Add New Hardware Wizard" will begin. Select "Search for the best driver for your device.". Check the "Removable media" and "Specify location" box.
5.2 Windows 2000 1. After inserting a DSCLP-100 for the first time, the "Add New Hardware Wizard will appear at start up. Click the "OK" button. 2. The following dialog box will be displayed. I nsert the Quatech COM CD (shipped with the device).
5.3 Windows 98 1. After inserting a DSCLP-100 for the first time, the "Add New Hardware Wizard will appear at start up. Click the "Next" button. 2. Select "Search for the best driver for you r device". Click the "Next" button.
4. The following dialog box will display the appropriate INF file on the disk in the drive. Click the "Next" button. 5. Window will copy the INF file from the disk and display a final dialog indication that the process is complete. Click the "Finish" button.
5.5 Using the "New Hardware Found" Wizard The following instructions provide step-by-step instructions on installing the DSCLP-100 in Windows 95 using the "New Har dware Found" wizard. 1. After booting the computer with a newly-installed DSCLP-100, the "New Hardware Found" dialog box will appear.
NOTE : You may be able to skip this step if you are certain that your system has the latest version of these files installed. If you do not have your Windows 95 install disks immediately available, click "OK" anyway. A dialog box appears with an option to Skip the files.
5.6 Viewing Resources with Device Manager This discussion applies equally to Windows 95/98/ME and 2000/XP . The following instructions provide step-by-step instructions on viewing resources used by the DSCLP-100 in Windows using the "Device Manager" utility.
Figure 12--- Windows Device Manager 6. The DSCLP-100 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. The DSCLP-100 ports will be enumerated starting with COM5 (or higher) even if lower logical numbers are available.
Figure 13 --- Windows Device Manager 9. Use the Logical COM Port names to access the serial ports on your DSCLP-100 through your software applications. Note: The Logical COM Port name is assigned to your ports by Windows . This name is required by a Windows application when accessing a particular p ort.
5.6.1 Changing Resource Settings with Device Manager 1. Start the Windows 95/98/ME Device Manager . 2. Double click on the hardware class Multi-Port Serial Adapters to list hardware devices in the class. 3. The DSCLP-100 “parent device” belongs to this hardware class.
4. Open the Properties dialog for the DSCLP-100 device, then click the Resources tab to view the Input/Output Range and Interrupt Request resource allocations. Do not change these settings without specific instructions from a Quatech Technical Support Specialist.
The X2 clock mode locks the ports hardware clock at double the standard rate. The baud rate the port runs at will always be double the rate requested by the applications. This mode is useful 230,400 X2 The X1 clock mode mimics a standard COM port. The hardware drivers lock the clock to the standard rate.
The X8 clock mode locks the ports hardware clock at eight times the standard rate. The baud rate the port runs at will always be eight times the rate requested by the application. This mode is useful for legacy applications which cannot request baud rates over 115.
8. Click the "Port Settings" tab and then click the "Advanced" button. The DSCLP-100 driver will display a custom Advanced Port Settings control, which allows the ports UART compatibility mode and FIFO threshold levels to be configured.

6 Other Operating Systems Device drivers for Windows NT and OS/2 are also available for the DSCLP-100. The board can be used under DOS and other operating systems as well in many circumstances. The software described below can be downloaded from the Quatech web site if it did not come with the board.
6.3.1 QTPCI.EXE Quatech's "QTPCI" utility supplies the information required when modifying the serial port settings of the application. This program should be run from real DOS, not in a Windows DOS box. Figure 14 shows the Basic Mode display for the DSCLP-100 after the "Q" key has been pressed.
Figure 15 shows the Expert Mode display for the DSCLP-100 after the "Q" key has been pressed. The information from the Basic Mode display is presented along with more details such as the Vendor and Device IDs, PCI Class Code, size of memory and I/O regions, etc.
7 External Connections RS-232-C devices are classified by their function as either Data Terminal Equipment (DTE) or Data Communication Equipment (DCE).
The DSCLP-100 is a DTE device which connects to peripheral equipment through a single male D- 25 connector, or using the adapter cable, two male D- 9 connectors.
