4. Operation of Display or Collector

When a single sensor is connected to the display/collector, it acts as a display. If more than one sensor is connected, it acts as collector.
In collector mode, no measured values are displayed on the screen. Instead, there is a list of the connected sensors.
In both modes, serial communication with the display/collector is possible. For more details, please refer to the associated protocol definition.
