Page 7: General Information
The QSC-200/300 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 Enhanced Serial Adapters can achieve data rates as high as 921,600 bits per second. -
Page 8: Features
1.1 Features The standard QSC-200/300 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 reliable use in an industrial environment. -
Page 9: Hardware Configuration
2 Hardware Configuration The QSC-200/300 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 jumper settings that control various hardware features. -
Page 10: Signal Connections
Two spare jumpers are installed in neutral positions. For details, refer to section 8.5. The QSC-200/300 is shipped from the factory with each channel configured as shown in Figure 2. -

3 Hardware Installation 1. Turn off the power of the computer system in which the QSC-200/300 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. -
Page 14: Address Map And Special Registers
QSC-200/300. 4.1 Base Address and Interrupt Level (IRQ) The base address and IRQ used by the QSC-200/300 are determined by the BIOS or operating system. Each serial port uses 8 consecutive I/O locations. The four ports reside in a single block of I/O space in eight byte increments, for a total of 32 contiguous bytes, as shown in Figure 7. -
Page 15: Enabling The Special Registers
Reading the Interrupt Status Register will return the interrupt status of the entire QSC-200/300, as shown in Figure 9. The individual bits are cleared as the interrupting ports are serviced. The interrupt service routine should ensure that the interrupt status register reads zero before exiting. -
Page 16: Clock Rate Multiplier
Figure 10--- Options Register bit definitions 4.4.1 Enhanced Serial Adapter Identification The ID bits are used to identify the QSC-200/300 as a Quatech Enhanced Serial Adapter. Logic operations are performed such that the values read back from these bits will not necessarily be the values that were written to them. - Page 17 A standard 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.

IRQ cannot be fixed at values such as 3F8 hex, IRQ 4 (COM1) or 2F8 hex, 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-200/300 must be able to accommodate any valid assignments of these resources. - Page 27 X - EXIT Figure 15 --- QTPCI.EXE Basic Mode display Figure 16 shows the Expert Mode display for the QSC-200/300 after the "Q" key has been pressed.

Any unauthorized repairs or modifications will void the QSC-200/300's warranty. Computer will not boot up. 1. Is the QSC-200/300 properly inserted? Remove the card and try again. Perhaps try a different expansion slot. 2. Ensure that an ISA-bus card is not using the same IRQ that the PCI BIOS tries to assign to the QSC-200/300. - Page 39 QSC-200/300 User's Manual Revision 1.13 November 20045 P/N: 940-0146-113 QSC-200/300 User's Manual...
