The DSCLP-100 is supported under several popular operating systems and environments. Contact the sales department for details on current software offerings. Most device drivers are available for download from the Quatech world wide web site at http://www.quatech.com. DSCLP/SSCLP-100 User's Manual...
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 X4, 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. It is also useful if the serial port device driver does not directly support setting the higher baud rates through the Options Register (see section 4.4).
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.
Interrupts are level-sensitive on the PCI bus. The base address and IRQ are automatically detected by the device drivers Quatech supplies for various operating systems. For cases where no device driver is available, such as for operation under DOS, Quatech supplies the "QTPCI"...
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. The Interrupt Status Register and Options Register are accessed through the scratchpad location of any UART.
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 Millennium 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. Click the "Next" button. Window will locate the proper INF file and copy the file from the CD.
After inserting a DSCLP-100 for the first time, the "Add New Hardware Wizard will appear at start up. Click the "OK" button. The following dialog box will be displayed. Insert the Quatech COM CD (shipped with the device). Click the "OK" button.
Select "Search for the best driver for your device". Click the "Next" button. On the next dialog, select the "CD-ROM DRIVE" check box. Insert the Quatech COM CD (shipped with the device) into the CD-ROM drive. Click the "Next" button. DSCLP/SSCLP-100 User's Manual...
The following dialog box will display the appropriate INF file on the disk in the drive. Click the "Next" button. Window will copy the INF file from the disk and display a final dialog indication that the process is complete. Click the "Finish" button. 5.4 Windows 95 Windows 95 maintains a registry of all known hardware installed in your computer.
3. An "Install From Disk" dialog box should pop up. Insert the disk 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.

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. Select Start|Help from within Windows for additional information on this utility. 1.

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. The threshold values of full-scale for the transmit buffer and ¾-scale for the receive buffer are optimal for most applications.

7 External Connections RS-232-C 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 devices.
