IQ-PIP-USP3/CN
8 Troubleshooting
Problem: IQ DATA indicator does not flash or illuminate, even
though a valid TCP/IQ command was sent.
Possible causes:
• Command was not addressed to the IQ-PIP-USP3/CN.
• Data cable is disconnected or broken.
To assist with troubleshooting, an option that forces the data indicator
to remain lit is available through the IQ software. Some Crown amplifi-
ers also have a data indicator on their front panels. In these cases this
indicator will light simultaneously with the PIP's data indicator.
Problem: Green Preset indicator is flashing, or is not flashing.
Possible cause: This is not a problem. This indicator signals the
number of the current preset, if active, by flashing a series of flashes
equal to the current preset number. A preset is considered “active” if
the PIP settings match those in the selected preset. If a change is made
to any setting then the preset is considered “inactive,” and the indicator
stops flashing.
Problem: Green LINK indicator is not lit.
Possible cause: Ethernet link is not present. Check Ethernet con-
nections to switch.
Problem: Yellow FAULT indicator is on.
Possible cause: An unexpected condition within the CobraNet inter-
face has been detected.
