For most computers, the default settings on our A/D converters work well. In the picture at left on
page 6, it appears that the Printer occupies IRQ Setting 07, but for most computers, our A/D
converters can share the IRQ 07 setting with a printer and conflicts will not arise. All computers have
multiple Base Address (Input/output) settings from which to choose.
Windows NT Users:
Find Available Base Address and IRQ Settings
1.
Go to
Start | Programs | Administrative Tools (Common) | Windows NT Diagnostics
.
2.
In the “Windows NT Diagnostics” dialog box, click on the
Resources
tab.
3.
Select the
IRQ
button. Find an available IRQ -- a number unassigned to a device.
4.
Select the
I/O Port
button. Find an available I/O Range (Base Address) -- a number or range of
numbers unassigned to a device. (The number is in hexadecimal.)
5.
Note these available settings. When you first run OOIChem, you must enter these values in the
“Configure Hardware” dialog box.
With Windows NT, devices cannot share IRQs; each device must be assigned a unique IRQ.
Install the PC2000
1.
Turn off the computer and remove the computer cover.
2.
Ground yourself to the computer chassis or power supply.
3.
Remove the PC2000 (spectrometer-A/D card combination) from its static-shielded bag.
4.
If necessary, change the position of the switches on the A/D converter. Position the switches to match
the available settings you found in the previous section -- numbers not being used by other hardware
devices. See
Appendix A
on page 34 for switch setting positions.
5.
Find an open ISA-bus slot and remove the slot protector.
6.
Insert the PC2000 into an available expansion slot on the motherboard connector by
gently
rocking the
card into the slot. Make sure the card is fully seated in the motherboard before screwing the tab on the
PC2000 to the computer. Do not bend the card or move it from side to side once it is seated in the slot.
7.
If you have a CHEM2000, take your 400-
µ
m fiber that came with your system and screw one end into
the SMA connector on your PC2000. If you have a CHEM2000-UV-VIS, take your 300-
µ
m
solarization-resistant fiber that came with your system and screw one end into the SMA connector on
your PC2000. Reinstall the cover.
