IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems
3.14 Memory Backup
A memor y backup feature is
provided which can be disabled, if
desired. The factory default setting
is “enabled.” When enabled, it
stores all run-time parameters that
can be controlled by the IQ
software into nonvolatile memory
(EEPROM) at approximately one
second intervals. When disabled,
all run-time parameters are
returned to the factory defaults
whenever the unit loses power.
CAUTION: Be careful to turn on the
memory backup feature if the input
attenuators will be used to set
critical levels. If the memor y
backup feature is turned off and the
IQ–P.I.P.-MEM loses power, the
attenuators will be reset to 0 dB,
resulting in the loudest possible
signal.
3.15 Reset
A recessed reset switch, acc-
essible from outside the PIP panel,
enables the IQ–P.I.P.-MEM to be
restored to one of two sets of
default settings. A straightened
paper clip or similar small object is
required to press the reset switch.
Press the reset switch for less than
2 seconds and all settings, except
the amplifier ID code or user scale
factors, will be reset with “user
default” parameters and the DSPI
will flash once. This feature is only
available if “user default” settings
have been previously established. If
none have, pressing the reset
switch for any length of time will
cause the unit to be reset to the
“factor y default” settings as
described below.
Press the reset switch for more than
2 seconds and the same settings
will be reset with “factory default”
parameters and the DSPI will flash
twice. After the unit has been reset
to the factory default settings, it will
behave like a standard P.I.P.-FX
until it is reprogrammed by an IQ
System or it is toggled to the “user
default” settings.
3.16 User Default Settings
The parameters for all functions,
except the amplifier ID code or user
scale factors, can be saved as
“user default” parameters. Then,
pressing the reset switch for less
than 2 seconds will restore all
settings to the “user default” values.
Please consult the documentation
of your IQ software for instructions
on setting the “user default” values.
