Displaying device trouble
Each Signature device is equipped with a 32-bit trouble register.
Should a device’s trouble bit be set at any time in the device’s
history, the device and the nature of the trouble will appear in the
Latching Troubles By Device Address window. Clicking on the
device will reveal a list of the trouble conditions affecting that
device. Click the device a second time to remove the trouble
listing.
