ADC1000 ISA-bus A/D Converter

The ADC1000 ISA-BUS A/D CONVERTER is a 12-bit, 8-channel, single-ended A/D card that connects our

spectrometers to desktop PCs. The PC2000 PC PLUG-IN SPECTROMETER has our 2048-element linear CCD-array

fiber optic spectrometer mounted onto an ADC1000. This sturdy combination fits easily into a slot in the PC. The

following are directions for installing your ADC1000 and PC2000. Because A/D converter installation goes hand-

in-hand with software installation, you will find directions for installing OOIBase32 Spectrometer Operating

Software included in this section as well.

Each device in or connected to your computer is assigned specific settings; it’s similar to giving each device its

own name so that your computer will know what to call and how to recognize the device. In order for your

ADC1000 or PC2000 to work as a device in your computer, it has to be assigned a Base Address setting and an

IRQ setting. The default settings for each are:

Base Address (I/O Range): 768 decimal (300 hexadecimal)

IRQ (Interrupt Request): 07

These default values are set on the A/D converter. There are dip switches on the A/D board and their positions

determine the values. These default values are set in the operating software as well. Most of the time, these default

settings will work with your computer. However, if you have many devices installed in your computer, you may

have a conflict; other devices may be using these settings. If there is a conflict with another device in your

computer, you must change the positions of the switches on the A/D board and change the values in the software.

For the ADC1000 and PC2000, there is only one bank of switches on the A/D board: the Base Address may be

changed via the first 6 switches and the IRQ may be changed via the last 3 switches. To first check your computer

to see which settings are available, follow the instructions for your Windows operating system.

Find Available Base Address and IRQ Settings

1. Go to Start | Settings | Control Panel and double-click on the System icon.

2. Choose the Device Manager tab and double-click on “Computer” at the top of the list.

3. Under View Resources, find available settings -- numbers unassigned to hardware. Note these available

settings for both the Interrupt request (IRQ) and the Input/output (Base Address). When you first run

OOIBase32, you must enter these values in the “Configure Hardware” dialog box. (Remember that

Input/output settings are expressed in hexadecimal.)

For most computers, the default settings work well. In the picture above left, it appears that the Printer occupies

IRQ 07, but for most computers, our A/D converters can share the 07 setting with a printer and conflicts will

not arise. All computers have multiple Base Address (Input/output) settings from which to choose.
