5.3 Manual Controls
All IQ P.I.P.s have manual controls which can be used to make real-time adjustments to one or more amplifiers.
They can be accessed both from a control block and a graphics plate.
5.3.1 Manual Control from a Control Block
Most of the manual controls are located in the amplifier control blocks. A sample is shown below in Figure 5.8.
All of the manual controls will be described next. However, not all controls are available for all IQ P.I.P.s. Refer to
the control blocks in Figure 5.2 to see which controls are available for the different models.
DSPI: The Data Signal Presence Indicator is an LED that flashes whenever the IQ P.I.P. is polled. The DSPI
control is used to force the indicator to stay on as an aid to the troubleshooting of communication on the Crown Bus.
Once the DSPI control is turned on, the DPSI will remain lit continuously even if the control block for another device
is selected. Turning off the DSPI control restores the indicator to its normal function of blinking when a valid IQ
command is received.
AUX: Toggles the IQ P.I.P’s AUX port output on and off. Note: IQ–P.I.P.–DP and IQ–P.I.P.–DSP models do not
have an AUX port.
DSP: The Digital Signal Processing control opens the amplifier Sub-block screen. It does
not turn the DSPI
functions on or off. See Section 5.5 for more details.
SEL: This control serves two purposes: it selects the amplifier to be included in either of the two Display screens
and it identifies the amplifier to have its GDM included in a graphics plate if the graphics plate is set to the Selected
mode.
ASA: The Auto System Activate control serves two purposes; it serves as a master control to turn all automated
control functions on and off. Turning ASA off, restores manual control while turning it on restores automatic
operation.
