How to use the pull-up resistor of Continuum I2/B3 controllers' input?

Issue

If the pull-up resistor is disabled falsely, the sensor value or status that connects with this input may be wrong. For example, sensing temperature value has a great deal of error with the actual temperature value.

Environment

I2 controllers

B3 controllers

Cause

If the pull-up resistor selection is wrong, the right value can not be gotten.

Resolution

The following is a schematic representation of the switch and its associated pull-up:

 pull-up

  1. To measure temperature, the pull-up resistor switch associated with this input must be enabled.
  2. To measure voltage, the pull-up resistor switch associated with this input is usually disabled (OFF).
  3. To sense contact closures (Digital signals), the pull-up resistor switch associated with this input must be enabled.
  4. To count Pulsing signals or contact closures, the pull-up resistor switch associated with this input must be enabled.
