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 Enhanced Serial Adapters can achieve data rates as high as 921,600 bits per second.
- Page 7 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 reliable use in an industrial environment.
- Page 8 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 opposite the D-37 connector. Any changes from the factory default should be made before installing the QSC-100 in the computer.

- Page 11 4.1 Base Address and Interrupt Level (IRQ) The base address and IRQ used by the QSC-100 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 5.

Reading the Interrupt Status Register will return the interrupt status of the entire QSC-100, as shown in Figure 7. 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 13: Options Register
Figure 9--- Options Register bit definitions 4.4.1 Enhanced Serial Adapter Identification The ID bits are used to identify the QSC-100 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 14 Figure 11 --- Rate Register bit definition At powerup and reset, the Options Register is initialized to 0. The QSC-100 will thus powerup in the x1 mode with software control of the clock rate multiplier enabled as long as the X2, X4, and X8 jumpers are not installed.

Windows 95 environment. Also a custom Windows 95 serial device driver is included with the QSC-100 to support the use of the 16750 UART's 64 byte FIFO. Windows 95 uses the "INF" file to determine the system resources required by the QSC-100, searches for available resources to fill the boards requirements, and then updates the hardware registry with an entry that allocates these resources. -

Any unauthorized repairs or modifications will void the QSC-100's warranty. Computer will not boot up. 1. Is the QSC-100 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-100. - Page 32 QSC-100 User's Manual Revision 1.11 March 2004 P/N: 940-0146-111 Quatech QSC-100 User's Manual Get other manuals https://www.bkmanuals.com...
