LDS30 Manual
General Information
The Laser Distance Sensor LDS30 was developed for industrial applications. It
enables non-contact measurement of distances in a large working range and
with a high sampling rate up to 30 kHz to almost any diffusely reflecting
surface to 30 m and up to 250 m on reflectors. The sensor uses an eye-safe
laser radiation at a wavelength of 905 nm (infrared).
It is available as a complete device LDS30A with various interfaces in an IP67
enclosure or as a module LDS30M for system integration. The IP67 model
variant is impact and shock resistant and ideally suited for use in harsh
industrial environments.
The LDS30A has an RS-232 or RS-422 interface, an analog output and 2 digital
outputs. The device is easy to install and operate. The module has just a RS422 interface with CMOS level.
The LDS30A is characterized by very compact and rugged design, easy
mounting, low power, adjustable switching outputs and the ability to set userspecific parameters. This opens up a variety of uses in industrial applications.

Rapid process monitoring
Position monitoring
Level measurement
Monitoring of object movements
Positioning of cranes and loading equipment
Measurement of inaccessible points, for example in cavities, pipes
and containers
Particularly suitable for use in scanners
The LDS30 sensor operates on the basis of time of flight measurement. Short
laser pulses are transmitted. The light pulse reflected from the target is
detected by the receiver. The distance can be determined by the time shift.
The measurement range depends on the reflectivity and the surface type of
the measuring target.

Serial interface RS-232
LDS30 Manual
The RS-232 serial interface can be used for data transfer and configuration of
the LDS30. The cable length is limited to 15 m. The cable length has to be
shorter at baud rates of 115200 or higher. For these baud rates, we
recommend only the use of the RS-422 model and the connection with 2
twisted pairs with shield.

Interface description
Serial interface RS-422
The RS-422 serial interface can be used for data transfer and configuration of
the LDS30 like the RS-232. Cable length depends on the baud rate and the line
quality; up to 300 m length is possible. Use only high-quality cable with 2
twisted pairs and shielding.

Q1/Q2 – Digital switching output
Q1 and Q2 supply distance readings as logic operation data. They output
events of positive or negative exceeding of a preset switching range with
hysteresis.
Accordingly, they are perfectly suited for direct processing of monitored
quantities such as filling level or for object detection. Parameter settings are
made via serial interface.
Figure 7 : Digital switching output Q1 and Q2 LDS30
A load resistance >150 Ohms must be connected to GND Power at the
switch output (max. 30 V operating voltage. 0.2 A max. load
current). It is important that the load current of 0.2 A will not be
exceeded.
Parameters will be set via the serial interface. The command is Q1w_x_y_z or
Q2w_x_y_z ("_" means space (0x20)).

QA – Analog output
The analog output enables the normed, analog transmission of distance data

Description of commands
Operating modes
DM – Individual distance measurement
The LDS30 carries out exactly one measurement and waits for new commands.
The duration of the measurement depends on the number of the set
measuring values SA and the preset measuring frequency MF.
Measuring time in seconds = SA / MF
Sample response to the input of DM (SD0 3):
D<SPACE>0002.935<SPACE>21.1<SPACE>57.8<CR><LF>

DT –Distance tracking
Continuous distance measurement stopped by certain command (RS-232/RS422: Escape = 0x1B).
The output rate of the measurement depends on the number of set
measurement values SA and the set measurement frequency MF:
Measurements per second = MF / SA
The maximum output data rate depends on the output format and the
selected measurement rate. With binary output the maximum output rate is
10 kHz
The maximum output rate with ASCII-coded output and different values for SA
at MF = 15.000 can be seen in Figure 13.

Description of commands
LDS30 Manual
Figure 13 : Maximum output rate at MF = 15.000
FT – Fast Distance Tracking
In fast distance tracking mode measurements are performed at a frequency of
30 kHz.
Measured data can be output in binary format only. The baud rate has to be
set to 921600 baud!
Caution: Some computer cannot handle baud rates >115200.
If you set by the command BR921600 the baud rate, no
communication will be possible without a compatible interface. The
baud rate cannot be reset to a lower value without a proper
hardware!
The current measurement can be terminated with the character ESC = 0x1B.
Distances >160 m causes incorrect distance measurements while
using the FT distance measurement mode.

Command for parameter setup
Parameters are set via serial interface. The command will be transferred to the
LDS30 with the final character 0x0D.
If commands have only one parameter, the parameter will be inserted directly
or separated by a blank space (0x20).
If commands have several parameters, these parameters will be separated by
a blank space (0x20).
AS – Auto start function
The auto start function defines the behavior of the LDS30 after a cold start.

ASTECH GmbH
Page 41
Description of commands
LDS30 Manual
Setting a very high baud rate implies a risk. Some computers cannot
support baud rates >115200.
If the baud rate is set by command BR460800, communication is no
longer possible without a compatible interface, i.e. the baud rate
cannot be reset to a lower value without hardware that supports
this baud rate!
We recommend the use of a suitable USB interface converter (RS232 to USB converter or RS-422 to USB converter that supports the
appropriate baud rate) and baud rates of 230400, 460800, 921600
for parameter setting and reset to a lower baud rate.
PR – Parameter reset
All parameters are reset to factory settings, except the baud rate! We do not
recommend to use this command. Afterwards the device must be
programmed new (auto start, scaling analogue and output etc.).

Description of commands
DR – Release of cold start
DR carries out a cold start of the LDS30 and actually simulates an interruption
of the supply voltage. This command is useful for a test if “Autostart”command was changed for example.
MW – Measurement window
The LDS30 outputs only measurement results inside the set measurement
window, starting with x and ending with y.
The measurement window is used e.g. for:

Blanking out interfering objects before and behind a measurement
range

Setting an specific measurement range
The object detection in front of or behind a measurement window will result
in either the output of an error message output or no output at all, according
to the settings of parameter z of MW.

For example: MF10000 means that 10.000 single measurement pulses per
second are sent. The measuring time and the transmission of the
measurement result via a serial interface also depend on the parameter SA
(averaging, see page 44):
Output time in seconds = SA / MF

SO – Set Offset
With the command SO, a single distance measurement is carried out and the
result will be set as OF (Offset). SO can only be executed, in this way, it is not a
parameter in the strict sense. SO is used for the zero-adjustment onto the
current distance.
SA – Average value
SA sets the number x of all single measurements to be averaged for one
measurement output. SA is directly related to MF (see also page 43):
Output time in seconds = SA / MF
or
Output frequency in Hz = MF / SA

UB – Unit for binary output format
UB sets the scaling factor for the binary output format.
Query:
UB
Set:
UBx
Value range x:
0.001 … float32;
resolution 0.001
Standard:
10.000
UB influences all outputs in binary format independent from the current
measurement frequency. The value for UB means the distance for one bit of
the binary output format.
Example:
UB 0.001 = 1 µm / bit
UB 10.000 = 10 mm / bit = 1 cm / bit
Binary distance value = Distance (mm) / UB
TE – Terminator of the serial interface
TE is used to set the terminator for the output of measured values in the ASCII
format (also see command SD).
