9 Utilities
This section describes the
IQ-PIP-USP2/CN Utility features.
Some of these features are accessed
via IQ for Windows software. Please
refer to the IQ for Windows docu-
mentation if you are unfamiliar with
IQ software.
9.1 User Presets
The parameters for all functions can
be saved as presets. A total of ten
user presets can be stored in the IQ-
PIP-USP2/CN’s flash memory. Pre-
set names are stored on the PIP.
9.2 Memory Backup
A memory backup feature is pro-
vided which can be disabled, if de-
sired. The factory default setting is
“enabled.” When enabled, the
memory backup stores all run-time
parameters that can be controlled
by the IQ software into nonvolatile
flash memory. Memory backup oc-
curs within 2 seconds after any pa-
rameter change. When disabled, all
run-time parameters are returned to
the last backed-up values when-
ever the unit loses power.
CAUTION: Care should be taken to
backup “safe” levels for the input
attenuators and output trim controls.
Changes made after disabling
backup are not saved; therefore, it
is possible for the memory backup
feature to be turned off with “unsafe”
levels stored. This may result in sig-
nificantly greater system gain the
next time power is re-applied to the
IQ-PIP-USP2/CN.
9.3 AUX Output
The AUX Output delivers 15 VDC at
10 mA maximum output when
switched to logic High, and may be
controlled via software or may be
programmed to switch when a fail
condition is present on any channel.
The logic of the AUX Output can be
set to either non-inverted (enabled
output transitions from low to high)
or inverted (enabled output transi-
tions from high to low).
9.4 AUX Input
The high-impedance (10 K ohm) AUX
Input can sense 5-35 VDC logic
signals and can be programmed to
any of seven different operating
modes as shown in Figure 9.1:
