IQ-PIP-USP3/CN
4.1 Hardware
4.1.1 Data Indicator
An amber Data indicator is provided on the front panel. It flashes whenever a command
addressed to the IQ-PIP-USP3/CN is received. To assist with troubleshooting, an option
that forces the data indicator to remain lit is available through the IQ software. Some Crown
amplifiers also have a data indicator on their front panels. In these cases this indicator will
light simultaneously as the PIP’s Data indicator.
4.1.2 Preset Indicator
A green Preset indicator is provided on the front panel. This indicator signals the number of
the current preset, if active, by continually flashing a series of flashes equal to the current
preset number, followed by a pause. 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 con-
sidered “inactive,” and the indicator stops flashing.
4.1.3 CobraNet Connectors
The Primary and Secondary CobraNet RJ45 connectors allow the USP3/CN to interface to
the 100Mb Ethernet based CobraNet network. While the Primary CobraNet connector is the
main connection to the CobraNet network, the Secondary connector is the "backup" or
redundant connection to the CobraNet network. If the Primary connection fails due to cut-
wire, failed network switch, etc., this port is automatically enabled and ready to receive the
CobraNet network data witin a few seconds. Connection is made using standard CAT5
cable to a network switch port. Crown strongly recommends the use of switches and not
hubs in the implementation of the CobraNet network. Use of hubs will limit the amount of
CobraNet traffic that can reside on the network and create unnecessary limitations in the
network.
4.1.4 CobraNet Link/Fault Indicator
Each CobraNet RJ45 connector has two indicators to show network status. The indicator on
the left side of each RJ45 connector is dual color. It flashes Green if the network link is con-
nected and operating normally, and turns ON Yellow to indicate detection of an unexpected
condition within the CobraNet interface (Fault).
4.1.5 CobraNet In-Use/Conductor Indicator
The indicator on the right side of each CobraNet RJ45 connector is also dual color. It turns
ON green if the port is "in-use" (i.e. the link is being used to transmit or receive active
CobraNet traffic), and turns ON Orange if the port is operating as the network "Conductor"
(See Section 4.3.1).
4.1.6 Balanced Audio Inputs
This 5 pin removable barrier block connector allows line level audio signals to be input to
the USP3/CN in addition to the digital audio that is available through the CobraNet network.
This analog audio can be used for one of three purposes:
