Polling of sensors is done sequentially and very fast (milliseconds per sensor).
The more sensors that are equipped, however, the more time it will take for
1WSwitch to recognize a missing or re-added sensor.
6.6. Options
6.6.1. On Board ADC Display (DAD)
The DAD (Display A to D) option is to enable or disable the on-chip voltage
sensor (Analog to Digital Converter, or ADC). The command DAD on enables
the display and DAD off disables the display.
The on-board ADC is available on pin 3 of J2 and referenced to the ground pin
available as pin 4 of J2. Be careful with connections to this ADC input. Note:
you are connecting directly to the processor, and input voltages greater
than 5 volts, or less than –0.6 volts, will damage the processor pin and
possibly the processor itself.
Activating the display results in the following kind of display during a Polling
