Connecting device electrically
1.
Connect the communication interface (Ethernet, 4-pin M12 female connector) of
the LiDAR sensor to the computer.
2.
Switch on computer.
3.
Supply the LiDAR sensor with voltage (5-pin M12 male connector, supply voltage
10 ... 30 V).
✓
After successful initialization, the
DEV
status LED lights up green. The device is
ready for use.

Connecting encoder
If the device is mounted for mobile use or if the objects to be measured are in motion,
the application will usually also need position data to further process the measured
values. Encoders can be connected for this purpose.
The encoder data is then available with the other measured values in a single scan
and at the same interface. A volume, for example, can be calculated by evaluating the
measurement data and position data (encoder ticks).
The input frequency of the encoder signal must not exceed 50 kHz.
The following incremental encoders with a push-pull output stage (HTL) can be used:
•
Single-channel, only connected at encoder IN1, no direction detection.
•
Dual-channel (phase), connected at encoder IN1 and encoder IN2; the pulses
have a phase shift of 90°, making direction detection possible. By definition,
during forward motion (CW = clockwise) phase 1 precedes phase 2; conversely,
during reverse motion (CCW = counterclockwise) edge 2 rises before edge 1.
•
Dual-channel (level), connected at encoder IN1 and encoder IN2; the pulses are at
encoder 1; at encoder 2, the direction is indicated by level 0 or level 1.
NOTE
Incremental encoder transmits a zero index signal often (encoder Z). This signal is not
processed by the device. It is therefore not necessary to apply the signal to the device.
