Reference Manual
5.1 Hardware
5.1.1 Data Indicator
An amber Data indicator is provided on the front panel. It flashes whenever a command
addressed to the PIP is received. To assist with troubleshooting, an option that forces the
data indicator to remain lit is available through the software. Some Crown amplifiers also
have a data indicator on their front panels. In these cases this indicator will light simulta-
neously as the PIP’s Data indicator.
5.1.2 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.
5.1.3 Network Connector
The network connector is a standard RJ-45 connector that allows the PIP to connect to an
Ethernet network. Connection is made using a standard CAT5 cable to a network switch
port. In cases where a PIP is used in stand-alone mode (not connected to an network) it can
be configured using a crossover cable (TX and RX pairs swapped) directly to a computer’s
network adapter port. The PIP-USP3/CN has both a primary and secondary network con-
nector (see Section 5.1.6).
5.1.4 Link/Activity Indicator
The Link/Activity indicator is provided on the network connector to display the status of the
Ethernet connection. Whenever the PIP is properly connected to another functioning net-
work port, the indicator lights. When the PIP detects the presence of network traffic, the
indicator flashes. Note: This differs from the Data indicator mentioned previously in that it
flashes for all network traffic, not just for commands addressed to this component.
5.1.5 100 Mb Indicator (PIP-Lite, USP3 only)
The green 100 Mb indicator is also provided on the network connector. It lights when the
PIP detects that it is connected with a 100 Megabit connection. Note: The PIP is compatible
with 10 Megabit Ethernet networks. However, a 10 Megabit network is not recommended,
especially for systems with a large number of IQ components
5.1.6 CobraNet Connectors (USP3/CN only)
The Primary and Secondary CobraNet RJ-45 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.
