This component configures the request-to-exit input associated with a specific door. This proxy extension serves the Request-to-Exit,
Sensor and Strike components.

To access one of these components, expand the in the Nav tree, then expand any of the Boolean points that have a Proxy Ext and double-click the node. Each door component’s Exit Request has a similar component: Request-to-Exit Input. Each Sensor’s Sensor Input component is also a proxy extension.
In addition to the standard properties (Status, Fault Cause, Enabled, Device Facets, Tuning Policy Name and Poll Frequency),
these unique properties support this component:

Configures the type of facet conversion for a specific point.
500 Ohm Shunt (nrio) applies only to a voltage input point used to read a 4–to-20mA sensor where the UI input requires a 500 ohm resistor wired
across (shunting) the input terminals. The input signal is 2 to 10V. Compared to a linear or generic tabular conversion, the
500–Ohm-Shunt conversion provides better resolution near the upper (20mA/10V) input range. This compensates for input clamping
protection and the circuitry automatically applies when input voltage rises above 3.9V.
Default automatically converts between similar units.
Linear applies to voltage input, resistive input and voltage output writable points, which, typically, need point output values
in some units other than device facets (voltage or resistance).
Linear With Unit
Reverse Polarity applies only to a Boolean input point or relay output writable. It reverses the logic of the hardware binary input or output.
Tabular Thermistor (nrio) provides an edit button ( ) that opens a window for editing the current ohms-to-degrees Celsius curve used by the proxy point, importing another thermistor
curve (.xml file) or exporting (saving) the current thermistor curve as an .xml file.
Thermistor Type 3 (nrio) applies only to a thermistor input point, where it provides a built-in input resistance-to-temperature value response curve
for Type 3 Thermistor temperature sensors.
