Networked PIP Series

5 Operation

The PIP-Lite, PIP-USP3 and PIP-USP3/CN are network components that allow control and
monitoring of the power amplifier over a standard 100 Mb Ethernet network. Connection to
the control computer is made through its standard network adapter.
The PIPs can function independently from the network control. Once the processing is con-
figured, the module's non-volatile memory allows the amplifier to continue to function with
no external control.
The USP3/CN provides a single-click solution for distribution of audio, control, and moni-
toring of the amplifier. A single CAT5 connection to a standard Fast Ethernet network used
for CobraNet control provides all of the necessary infrastructure wiring. The software can set
up CobraNet audio routing and addressing. In the unlikely event of a network failure, the
analog audio balanced inputs provide a backup audio path that can be automatically
selected by the USP3/CN if CobraNet audio is disrupted.
Crown strongly recommends the use of a 100 Mb Ethernet network for control and monitor-
ing. While some Crown products will function on a 10 Mb Ethernet network, their perfor-
mance and network expansion capability will be limited.
