1 General Information The Quatech, Inc. DSCLP-100 (two-port) and SSCLP-100 (one-port) provides upto two 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. Legacy serial port data rates are li[...]

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. Jumpers J 2, J 4 -J 5 are grouped together at the end of t[...]

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 page 0 ). If one of these j[...]

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. Install the DSCLP-100 in any empty PCI expansion slot. The board should be secured by [...]

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. This material will be of interest to programmers writing driver software for the DSCLP-100. 4 . 1 Base Address and Interrupt Level (IRQ ) The base address and IRQ used by the DSCLP-100 are determ[...]

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 (J6) is removed (factory default). They replace the UART Scratchpad Register on accesses to register address 7. The Interrupt Status Register and Options Register ar[...]

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 8 shows the structure of the Options Register. The powerup default of the Options Register is all bits zero. Clock rate multiplier bit 0 RR0 0 Clock rate mu[...]

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. This is controlled by the clock rate multiplier bits in the Options Register. Software can [...]

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[...]

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.
