In most cases the AVL will read the I-button within a few seconds except if the unit is sending data or
any other inputs are activated (like Panic input). In this case it will take longer to read the I-button.
Measuring temperature using the AUX3 input:
The AUX3 input voltage will change when the temperature changes. Most Thermistors are at normal
resistance (in above example we use 10 K) at 25 degrees. So in our example that will be 10K.
The input voltage to AUX3 will then be 1.27 Volt (ADC value will be 128 decimal or 80 hex).
The input voltage is always included in the ‘location message’ and can be configured to activate below or
above set value.
