Troubleshooting
Cary 50 Spectrophotometer Hardware Manual

Problem
The ‘Start’ button will not become active or the ‘Connect’ button will
not change to ‘Start’.
Solution
If the Cary software cannot locate the Cary 50 PCI card, the ‘Start’
button will not become active or the ‘Connect’ button will not change
to ‘Start’. This is due to either:
A memory address conflict with the Cary 50 PCI card and
another card in the computer.
An IRQ conflict with another card.
An I/O address conflict with another card.
A defective Cary 50 PCI card.
To fix the problem when using Windows XP:
1
Uninstall the Cary WinUV software (see Page 28).
2
Uninstall the Cary 50 driver (see Page 19).
3
Ensure the computer is turned off and the power cable has been
removed. Remove the Cary 50 PCI card from the computer.
4
Restart the computer.
5
Reinstall the Cary WinUV software and Cary 50 PCI according to
the Cary 50 Installation Instructions (publication number
8510185100).
6
Check that the computer is now communicating with the Cary
instrument — when you open an application the ‘Start’ button
should become active or when the ‘Connect’ button is clicked, it
should change to ‘Start’.
