1. Introduction
The purpose of this document is to give guidelines for connection and use of the Terabee
IND-TOF-1 distance sensor with a Personal Computer (PC).
2. PC setup instructions
The following section provides guidelines on connection and sensor evaluation on a PC,
using Microsoft®Windows®OS. This includes instructions on hardware arrangement,
software setup using MODBUS Doctor application (v2.7) and examples on executing
commands for modifying some of the basic sensor parameters.
Please note that standard RS485-to-USB converter and M12 Male-Female cable are
required for connecting and operating the Terabee IND-TOF-1 sensor with a PC. Please
find below links to reference components used for the purposes of this document:
●RS485-to-USB converter
●M12 Male-Female cable, 5 pin

2.1. Hardware setup
Figure 2 illustrates connection logic between the IND-TOF-1 sensor and a PC, and the
following components are required for a complete setup:
●Terabee IND-TOF-1 distance sensor
●Straight M12 5-pin A-coded cable of your preference (not provided by Terabee)
●RS485-to-USB adapter (not provided by Terabee)
●USB cable with Type B connector (not provided by Terabee)
●Control Unit (PC)
●Power Supply capable of supplying 24 V DC @ 100mA
Figure 2. Sensor and PC hardware setup diagram
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 sensor's M12, 5-pin connector.
Step 2
Connect the data lines of the M12 cable to the D-Sub 09 PoS (DB9) male connector of the
RS485-to-USB adapter. See wiring instructions in Table 2.

Step 3
Connect the power lines of the M12 cable to a power supply source. See wiring instructions
in Table 3. Wire +24 V (pin) and GND (pin) to the selected power supply (capable of providing
24 V supply).

Step 4
By using a USB cable, connect the RS485-to-USB adapter to the USB port of your PC. Please
note that the USB cable must support connectivity with a Type B connector on the adapter
side, and a preferred connector on the users PC side (Type A, Type C, etc.)
Step 5
Power the sensor by turning on the power source.
Step 6
The sensor's LED indicator PWR will now constantly stay ON (RED) to confirm proper voltage
supply.
Step 7
The hardware setup is completed and the user can now proceed to configuring basic
software parameters.
During power up the sensor will apply the last operating mode used or mode 1 (factory
default) if it is used for the first time.
Note: The NO/NC line is not used in this setup, it can be left floating or shorted to
ground

2.2. Software setup
As the Terabee IND-TOF-1 sensor uses the MODBUS RTU protocol for data communication
via RS485 interface, for operation on PC we recommend to work with MODBUS Doctor
freeware utility software (KScada). To do so, please follow the link below to the official page
of KScada and download the MODBUS Doctor software.
Link to MODBUS Doctor download page: http://www.kscada.com/modbusdoctor.html
2.2.1. MODBUS Doctor software configuration
After successful download, initiate the software on your PC. Next, select RTU to make sure
the following settings are configured accordingly:
●Baud rate: 19200
●Data bits: 8
●Stop bits: 1
●Parity: even
●Port Name: select the USB port on which the RS485-to-USB adapter is connected
For visual instructions please consult Figure 3. Once these parameters are configured, click
“Connection”. Contact with the sensor should now be established and the Status (bottom
left) should change to “Connected”. Figure 4 illustrates a successful connection.

2.3. Basic sensor parameter configuration
To learn more about IND-TOF-1 operating modes and their setup and functionality,
please refer to the official product user manual.
To learn more about all configurable sensor parameters, please refer to the official
product user manual.
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 (inquire) live
distance data from the sensor, please execute the following READ command:
Read distance data:
●Slave ID: 1 to 247 (enter corresponding slave ID, 1 in our case)
●Type (function): 04 Input Register
●Address location: 0
●Length (Quantity): 2
Click “READING” to execute the command. The distance data is now read from the sensor,
and displayed in the “Value” field. During the data read, the sensors onboard LED indicator

(Sel) will blink BLUE to signal that the slave device (sensor) has been successfully selected by
the master device, and the LED indicator (Tx) will blink RED, to confirm successful data
transmission via RS485. Visual instructions for executing the “read distance data” command
are illustrated in Figure 5. The status indicator will also show “Request OK (1/1)”.
Figure 5. Read distance data command execution example
2.3.2. Switching between operating modes
Terabee IND-TOF-1 provides users with 6 operating modes (learn more about each mode
functionality in the official user manual). By default the sensor is shipped with operating
mode 1 pre-set. To switch between operating modes, execute the following WRITE
command/s:
Write operating mode:
●Slave ID: 1 to 247
●Type (Function): 03 Input Register
●Register: 14
●Length: 1
●Value: 1 to 6 (1 for mode 1, 2 for mode 2, etc.)
Figure 6 illustrates an example for setting operating mode 2. In this case, input value 2 in
the “Length” field and click “WRITING” to execute the command.
The LED indicators (Tx; Sel) will blink RED and BLUE.

2.3.3. Verify operating mode example
A quick READ command can be executed to verify that the new operating mode has been
successfully applied by the sensor.
Read operating mode:
●Slave ID: Slave ID: 1 to 247 (enter corresponding slave ID, 1 in our case)
●Type (Function): 03 Holding Register
●Register: 14
●Length: 1
Click “READING” to execute the command. The LED indicators (Tx; Sel) will blink RED and BLUE.
Operating mode number is now displayed in the “Value” field.
