1. General Information The Quatech, Inc. QS-100D provides four RS-232 asynchronous serial communication interfaces for IBM-compatible personal computer systems using the 16-bit ISA (Industry Standard Architecture) expansion bus. The QS-100D is highly flexible with respect to addressing and interrupt level use.
1.1.1 IND Package The IND upgrade on the QS-100IND and QS-100IND750 boards provides the protection essential for reliable use in an industrial environ ment.

2. Hardware Installation If the default address and interrupt settings are sufficient, the QS-100D can be quickly installed and put to use. The factory defaults are listed in Figure 3.
2.1 Setting the Base Address The base address of the QS-100D is set using the two DIP switch packs. When setting the address selection switches, a switch in the "ON" position specifies that the corresponding address line must be a logic 0 for the port to be selected.
two, and one, hence the max im um value of 8+4+2+1 = 15. A serial port's address is a 16-bit quantity that is most of ten expres sed in four hex adecim al (base 16) digits. A hex digit can hold a value f rom 0 to 15 (decim al), and is made up of four binar y bits given weights of eight, four, A possible ser ial port address is 5220 hex.
2.2 Setting the Interrupt Level (IRQ) The QS-100D allows the use of any interrupt level in the range IRQ2 to IRQ7, IRQ10 to IRQ12, IRQ14, or IRQ15, selected using jumper pack J6. (Early versions of the QS-100D are limited to IRQ2-7.) In Figure 6 , the factory default setting of IRQ3 is shown.
The QS-100D signals a hardware interrupt when any port requires service. The interrupt signal is maintained until no port requires service. Because the ISA bus is edge-sensitive, this behavior forces the interrupt service routine to ensure that all ports are checked before exiting.
Serial 1 --- 1 if interrupt pending 0 Serial 2 --- 1 if interrupt pending 1 Serial 3 --- 1 if interrupt pending 2 Serial 4 --- 1 if interrupt pending 3 0 (not used) 4 0 (not used) 5 0 (not used) 6 0 (not used) 7 (MSB) Figure 9 --- Interrupt Status Register contents 2-6 Quatech Inc.
3. Windows 95 Configuration Windows 95 maintains a registry of all known hardware installed in your computer. Inside this hardware registry Windows 95 keeps track of all of your system resources, such as I/O locations, IRQ levels, and DMA channels.
5. A list box opens with Manufacturers on the left and the associated board Models on the right. Click the “Have Disk” button. 6. An Install From Disk dialog box should pop up. Insert the diskette with the Quatech INF files on it, select the correct drive letter, and click the “OK” button.
12. You are required to manually configure the QS-100D to match the resources allocated by Windows 95. Another option is to use the “Device Manager” in Windows 95 to change the system resources allocated in Windows 95 to match your preferences. See chapter 2 for information on installing and configuring the QS-100D.
Figure 10--- Windows 95 Device Manager 6. If the “Change Settings” button was selected an Edit Resource window will open up. Inside these Edit Resource windows click on the up/down arrows to the right of the resource value. This scrolls you through all of the allowable resources for your hardware.
which allows the ports UART compatibility mode and FIFO levels to be configured. Note that FIFO option for each of the four ports QS-100D ports is configured independently.

4. External Connections RS-232-C devices are classified by their function as either Data Terminal Equipment (DTE) or Data Communication Equipment (DCE).
The QS-100D connects to peripheral equipment through a single female D-37 connector, or using the adapter cable, four male D-25 connectors. The standard serial port connections are listed in Figure 14 .
5. Specifications Bus interface: Industry Standard Architecture (ISA) 16-bit bus IBM PC-AT TM compatible Dimensions: 6.65" x 3.7" Serial ports Controller: 16550 (16750 optional) Interface: One female D-37 connector Four male D-25 connectors using adapter cable Transmit drivers: MC1488 or compatible High level output: +9V min, +10.
