Part 28— Analog Scaling Buffer about 50%
The Analog Scaling Buffer about 50% symbol in Crestron SIMPL Windows is used to scale an analog value around a midpoint of 50%. This symbol is useful when you need to limit the range of an input signal to a narrower band around 50%, effectively creating a scaling window centered around that midpoint.
How It Works:
Scale Factor (scale_factor): The percentage value (from 0% to 100%) that defines how much of the input signal will be passed through to the output. This scale factor limits the output to a range that is above and below 50%. For example, a scale factor of 50% would narrow the output to range between 25% and 75%, effectively limiting the full range of the input signal.
Analog Inputs (ain1 through ain999): These are the input signals that will be scaled according to the scale_factor.
Analog Outputs (aout1 through aout999): These are the outputs that are scaled relative to the 50% midpoint. The output values will be the result of scaling the input values above and below 50%, as per the given scale_factor.
Example Application:
Example 1: Camera Pan/Tilt Sensitivity
Scenario: You have a PTZ camera with pan and tilt controls that can move between 0% and 100%, but you want to limit its sensitivity (speed of movement) when zoomed in. The goal is to limit the pan/tilt range to, for example, 25% to 75%, to avoid over-responding to small movements.
