1 General Information The Quatech, Inc. QSC(LP)-100 provides four RS-232 asynchronous serial communication interfaces for Low Profile I BM-compatible personal computer systems using the PCI expansion bus. The QSC(LP)-100 uses Quatech's new Enhanced Serial Adapter design. Legacy serial port data rates are limited to a maximum of 115,200 bits pe[...]

2 Hardware Configuration The QSC(LP)-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 J2-J5 are grouped together at the end of the boa[...]

2.3 Force High-Speed UART Clock (X2, X4, or X8, J3-J5) These jumpers force an increase of the UART input clock frequency by a factor of two, four, or eight. 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 rate[...]

3 Hardware Installation 1. Turn off the power of the computer system in which the QSC(LP)-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 QSC(LP)-100 in any empty PCI expansion slot. The board should be secured[...]

4 Address Map and Special Registers This chapter explains how the four 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 QSC(LP)-100. 4.1 Base Address and Interrupt Level (IRQ) The base address and IRQ used by the QSC(LP)-100 are dete[...]

4.2 Enabling the Special Registers The QSC(LP)-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 QSC(LP)-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. 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 dete[...]

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 port will run at the baud rate requested[...]

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 115.200. 921,600 X8 The X4 clock mode locks the ports hardware clock at four times the st[...]
