• Number of connected sensors:
The number of currently registered sensors is shown in a range from 1 to 10 in
hexadecimal (between 1 and 16 in decimal).
• Number of sensors that can be communicated with:
The number of current sensors that can be communicated with is shown in a range from
0 to 10 in hexadecimal (between 0 and 16 in decimal).
When failure occurs, you can confirm how many sensors are communicating normally.
• Sensor communications error:
When the registered number of connected sensors doesn't match the number of sensors
that can be communicated, or when communications with a sensor fail after the
connection with the sensor is established, it is turned ON.
• Communicating with a sensor: When the communication with a sensor is established, it
is turned ON.
