Default factory reset
The sensor can be reverted back to its default settings (configurable sensor parameters) at
any time. This can be done using the following Modbus-like serial command:
{Slave ID} 0xFF {CRC16-Modbus}
Example for Slave ID 1 (default): 0x01 0xFF 0x40 0x60
To confirm that the reset has been successful, The LED indicators, TH1 and TH2 will blink
GREEN and RED alternatively 10 times, and then both indicators will change its status to
continuous ON (GREEN). The sensor will reply via RS485 interface, Modbus-like format (its
own a 0xFF + CRC16-Modbus) with a slave ID 1.

Projected reception area
Terabee IND-TOF-1 is an optical distance measurement sensor, that uses infrared
Time-of-Flight principle. The sensor features a 2 degree Field of View, which corresponds to
a detection area of 3.5 cm (spot diameter in reception) at 1 m range, 10.5 cm (spot
diameter) at 3 m range, and scales linearly with distance. Figure 25 illustrates spotlight
geometry of the sensor at different reference distances.
