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

1 . 1 Features The standard QSC-100 implements each of its communication channels with a 16750 UART and uses standard line driver and receiver components. For improved performance and industrial-grade reliability . 1 . 1 . 1 "IND" Option --- Surge Suppression Upgrade The "IND" upgrade provides the protection essential for reliab[...]

2 Hardware Configuration The QSC-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 J3-J6 are grouped together at the end of the board o[...]

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 ra[...]

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

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-100. 4 . 1 Base Address and Interrupt Level (IRQ ) The base address and IRQ used by the QSC-100 are determine[...]

4 . 2 Enabling the Special Registers The QSC-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 are [...]

4 . 4 Options Register The Options Register allows software to identify the QSC-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 mult[...]

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 ca[...]

9. Use the Logical COM Port n ames to access the serial ports on your QSC-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 application when accessing a particular port. 5 . 6 Windows NT Device drivers for Windows NT and OS/2 are also available for the[...]

6 DOS and Other Operating Systems The QSC-100 is n o t a direct drop-in replacement for a legacy serial port because its base address and IRQ 3 (COM2), etc. Rather, the system BIOS assigns the address and the IRQ in a plug-and-play fashion at boot time. Software which is to use the QSC-100 must be able to accommodate any valid assignments of these [...]
