Analog Min/Max Detection
An analog input can be configured so that an action is triggered if the captured value is
above a user-defined Maximum value and/or under a user-defined Minimum value. The ac-
tions that can be selected are the same as these that can be triggered by the Digital Input.
See the list and description in Table 4.1, “Digital Input Action List” on page 58.
Min, Max and Center adjustment
The raw analog capture is then scaled into a number ranging from -1000 to +1000 based
on user-defined Minimum, Maximum and Center values for the input. For example, setting
the minimum to 500mV, the center to 2000mV, and the maximum to 4500mV, will pro-
duce the output to change in relation to the input as shown in the graph below

This feature allows capturing command or feedback values that match the available range
of the input sensor (typically a potentiometer).
For example, this capability is useful for modifying the active joystick travel area. The figure
below shows a transmitter whose joystick’s center position has been moved back so that the
operator has a finer control of the speed in the forward direction than in the reverse position.
