IQ-PIP-USP2/CN Reference Manual
11 Specifications
11.1 General
Internal Controls:
An 8-segment
DIP switch sets the IQ address (deci-
mal range: 1–250).* A Reset/Preset
switch, accessible with a straight-
ened paper clip through the PIP
panel, selects the next user preset if
pressed for less than 2 seconds,
resets the PIP to preset “0” if pressed
for more than 2 seconds, or restores
all settings and presets to factory
default if pressed while applying
power.
Connectors:
IQ Bus: RJ-45 con-
nector for input, RJ-45 connector for
output. AUX In/Aux Out: RJ-11 con-
nector. CobraNet Digital Audio In-
put and Output: RJ-45 connector for
Primary Network, RJ-45 connector
for Secondary Network.
Indicators:
A yellow DATA indica-
tor flashes when a valid IQ com-
mand is received from the IQ Sys-
tem via the IQ Bus. A green PRESET
indicator flashes to indicate the user
preset number currently selected in
memory (if the PRESET indicator
does not flash the preset number
when selected, this indicates the
preset has been modified by the
user). Two dual-color indicators pro-
vide status of the CobraNet™ net-
work. The left indicator on the Pri-
mary and Secondary RJ-45 con-
nectors flashes green if the network
link is connected and operating nor-
mally, and flashes red if the port is in
* If address “0” is selected, the
IQ-PIP-USP2/CN will operate in stand-
alone mode. In this mode, the IQ Bus
port is deactivated.
a “Fault” condition. The right indica-
tor on the Primary and Secondary
RJ-45 connectors is ON green if the
port is “in-use,” and is ON orange if
the port is operating as the network
“Conductor.”
Memory Backup:
1 Mbyte non-vola-
tile FLASH memory for backup of
run-time parameters, presets, and
program storage. Capable of greater
than 10-year data retention and es-
timated 20+ year life-cycle.
Power Requirements:
Power draw:
410 mA @ +24 VDC and 40 mA @ –
24 VDC. When installed into a Crown
PIP2-compatible amplifier, the unit
receives ±24 VDC from the ampli-
fier. No external power is required.
Total Power Dissipation:
10.5 watts.
11.2 IQ Bus Data
Communication
Protection:
If IQ communication is
lost, the unit will continue to function
with the last commands received.
Data Rate:
38.4 K BAUD.
Data Format:
Serial, binary, asyn-
chronous; 1 start bit; 1 stop bit; 8
data bits; no parity.
IQ Bus Interface Type:
Optically
isolated 20 milliamp serial loop.
Operation:
Half duplex.
Transmission Distance:
Variable
from 200 to 3000 feet (61 to 914 m),
depending upon wire capacitance.
Typically 1000 feet (305 M) using
shielded twisted-pair wire, #26 AWG
