When the connection with the Mobile Console is established, it is turned ON.
Once the Mobile Console is connected, either Explicit message communications or
setting/monitoring operations from the Configurator cannot be performed.
For Sensors that occupy two units, two bits of ON/OFF output data are occupied.In addition, one
sensor occupies two units.
