The following summarizes the steps to be taken for connecting the IND-TOF-1 sensor to
a PC.

Please note that there is some soldering involved, as the M12 connector is not directly
compatible with the D-Sub 09 PoS connector of the RS485-to-USB adapter.

Step 1
Connect the M12 cable to the sensors M12, 5-pin connector.

Step 2
Connect the data lines of the M12 cable to the D-Sub 09 PoS (DB9) male connector of                


Step 5
Power the sensor by turning on the power source.

Step 6
The sensors LED indicator PWR will now constantly stay ON (RED) to confirm proper             

2.3.1. Read distance data example

The MODBUS protocol uses a master/slave architecture of communication where one          
device or process has unidirectional control over one or more devices. In order to read              
