1. General Information

The Quatech, Inc. DS-100 provides two RS-232 asynchronous serial communication interfaces

for IBM-compatible personal computer systems using the 16-bit ISA (Industry Standard

Architecture) expansion bus.

The DS-100's serial ports are implemented using 16550 Universal Asynchronous

Receiver/Transmitters (UARTs). The 16550 UARTs enable the DS-100 to transmit and receive

data at a rate of up to 115.2 kbaud. The 16550 contains a 16-byte hardware buffer that reduces

processing overhead. To use the 16550’s buffering capabilities, the software must be aware of

the UART's presence. Otherwise, it will act as a 16450 UART.

The DS-100 is highly flexible with respect to addressing and interrupt level use. The serial ports

are individually addressed and can be placed anywhere within the range of 0000 hex to FFF8 hex

at 0008 hex intervals. Available interrupt levels include IRQ2 to IRQ7, IRQ10 to IRQ12,

IRQ14, or IRQ15.

Both ports on the DS-100 can share one interrupt level or an interrupt level can be shared with

another Quatech adapter that supports interrupt sharing. The shared interrupt feature minimizes

the system resources consumed by the adapter.

In order to support the use of the shared interrupt feature of the DS-100, Quatech has developed

device drivers for several popular operating systems and environments. The sales department

can be contacted for details on current offerings.

2. Installation

If the default address and interrupt settings are sufficient, the DS-100 can be quickly installed and

put to use. The factory defaults are listed in Figure 1.

YES43F8 hexSerial 0

ENABLEDIRQADDRESSPORT

Figure 1 --- Default address and IRQ settings for DS-100

The output of the DS-100 is two 9-pin D-connectors labeled CN1 (serial 0) and CN2 (serial 1).

1. If the default settings are correct, skip to step 2, otherwise refer to sections 4 and 5 of this

document for detailed information on how to set the address and IRQ level.

2. Turn off the power of the computer system in which the DS-100 is to be installed.

3. Remove the system cover according to the instructions provided by the computer

manufacturer.

4. Install the DS-100 in any vacant expansion slot. The board should be secured by

installing the Option Retaining Bracket (ORB) screw.

5. Replace the system cover according to the instructions provided by the computer

manufacturer.

6. Attach and secure the cable connectors to the desired equipment.

3. Windows 2000 Configuration

Windows 2000 maintains a registry of all known hardware installed in the computer. Inside the

hardware registry Windows 2000 keeps track of all of the system resources, such as I/O

locations, IRQ levels, and DMA channels. The “Add New Hardware Wizard” utility in

Windows is designed to add new hardware and update this registry.

Windows 2000 will not

automatically configure the DS-100. The user is required to manually

configure Windows 2000 to match the resources set on the card.

3.1 Using the Add New Hardware Wizard

The following instructions provide a step-by-step instructions on installing the DS-100 Enhanced

Serial Adapter in Windows 2000 using the “Add New Hardware” wizard.

1. Select Start>Settings>Controll Panel.

3-1 Quatech Inc.

2. Double click on the “Add New Hardware” icon.

3-2 Quatech Inc.

3. The next window will be the “Welcome to the Hardware Wizard”, click “Next”.

4. Next choose the “Add/Troublshoot a device” radio button, click “Next”.

3-6 Quatech Inc.

7. Next select “Ports (COM & LPT)”, click “Next”.

3-7 Quatech Inc.

8. In the next window under manufacture select “(Standard port types), and under Models select

“Communications Port.

Because Windows will not detect plug and play you will have to manually enter the settings.

Click “OK”.

3-8 Quatech Inc.

9. Next you will have to change the “Input/Output Range” to a setting that is not in use “No

conflicts” by choosing a different “Basic Configuration”.

.

3-9 Quatech Inc.

10. The “Input Request” (IRQ) must be set to corresponds with the jumpers setting on the

DS-100 board.

3-10 Quatech Inc.

Once you have chosen the IRQ that corresponds with the setting on the Quatech DS-100 card the

window will display “no conflicts” and the red circle with a slash of the “Input/Output Range”

will not be present.
