General LDM41E and LDM42E Manual

1 General
The LDM41E and LDM42E is a Laser sensor to measure distances from 0.1 m to
more than 100 m with pinpoint accuracy.
A given target can be clearly identified with the help of a red Laser sighting
point. In terms of operating reach, the LDM41E and LDM42E performs
depending on the reflectance, morphology and qualities of the target to be
measured.
The sensor works based on comparative phase measurement. It emits
modulated Laser light which is diffusely reflected back from the target with a
certain shift in phase to be compared with a reference signal. From the
amount of phase shift, a required distance can then be determined with
millimeter accuracy.
Figure 1 : Measurement principle
A distance measuring cycle can be triggered in three different ways:
By sending a command from the PC or another equivalent control
unit
By making appropriate prior parameter settings for the auto start
command and applying supply voltage
By external triggering (in remote-trigger mode).
For a more detailed description of these three trigger options, you should
consult chapter 8, Commands and Parameter of this User Manual.

2 Safety Instructions
2.1 General Safety Instructions
These safety and operating instructions should be carefully read and followed
during practical work with the LDM41E and LDM42E.
There is danger of Laser radiation or electrical shock. For necessary
repair work, the LDM41E and LDM42E may not be opened by anyone
other than Manufacturer personnel. Unauthorized intervention into
the inner product space will void any warranty claims.
Compliance with all specified operating conditions is necessary.
Failure to observe advisory notes or nonconforming product usage may cause
physical injury to the user or material damage to the LDM41E and LDM42E.
Cable connectors must not be plugged or unplugged under voltage.
Remember to turn voltage supply off before you begin working on cable
connections.
2.2 Intended & Conforming Use
Measurement of distances
Special measuring functions
Compliance with prescribed temperatures for operation/storage
Operation at correct voltage level
Application of specified signal levels to the appropriate data lines
2.3 Nonconforming use
Do not operate the LDM41E and LDM42E in any other way than
described under "Intended & Conforming Use" above and only in a
proper working condition
Safety devices must not be defeated or otherwise rendered
ineffective
Information and warning signs must not be removed
Repair work on the LDM41E and LDM42E must not be carried out
by anyone other than authorized personnel.
Page 9
LDM41E and LDM42E Manual Safety Instructions
ASTECH GmbH Page 9
Refrain from using the LDM41E and LDM42E without certified
protection in an explosive environment
Measurement with the LDM41E and LDM42E pointed at the sun or
other strong light sources may produce faulty results
Measurement of targets with poor surface reflectance in a strongly
reflecting environment may also result faulty measurements.
Measurement of strongly reflecting surfaces may deliver faulty
results.
Measurement performed through transparent optical media, for
example glass, optical filters, Plexiglas, etc. may equally produce
incorrect results.
Measurement on translucent objects (materials allow light to pass
through, but are not transparency, e.g. polystyrene, wax, different
plastics etc.) can give a too large measured value, since also light is
reflected by deeper layers
Rapidly changing measuring conditions are likely to falsify the result
of measurement
2.4 Laser Classification
The LDM41E and LDM42E are Class 2 laser product, ≤1 mW as stipulated in
EN60825-1:2007, Class 2.
Caution:
There is Class 2 Laser radiation. Do not stare into beam!
Figure 2 : Warning Sign Laser Radiation Class 2
The Laser power is limited to maximum 1 mW. The Laser radiation is visible. A
short-term exposure (duration up to 0.25 s) is harmless to the eye.
Users are instructed by Laser warning sign (see Figure 2) to do not stare into
the beam. They have to protect themselves by turn the head and/or closing
the eyes and by avoid a long look into the beam.
Page 10
Safety Instructions LDM41E and LDM42E Manual

RS232 Serial Interface
Note: All commands in Chapter 8 are possible with the RS232 and
also with Ethernet (Telnet)! The use of RS232 can therefore usually be
avoided!
The RS232 interface was originally designed as a PC interface only. It has now
become the standard for serial data transfer for short distances. It is subject to
interference when used for longer distances, in particular, in environments
with interfering high-frequency electromagnetic radiance. As a result, this
interface should only be used for configuring the LDM41E and LDM42E. Please
configure using the programming cable and the LDMTool program.
Note: The receiving line of the RS232 serial interface of the LDM41E
and LDM42E is deactivated while connecting to the Telnet-client. If
the Telnet connection is terminated, the full use of the RS232 is again
possible.
Please observe the RS232 standard. The maximum extension of the
RS232 lines is 15 m.

5.3 Shield and Grounding
Cable shields must be grounded with low resistance. Only high quality shielded
cables should be used.
Carrier bases and control boxes should have equal potential. Potential
differences could lead to electrical currents and may cause EMC problems (no
correct measurement function or switching the gauge off or on is necessary).
If no potential equalization is possible, then mount the LDM41E and LDM42E
isolated from the carrier base (use nylon screws and washers). Connect the
screen with mass to the cable end. This way of assembly should also be used
when installing the LDM41E and LDM42E inside vehicles

7 Start up
Make sure that all cable ends are protected against short circuit effects before
you turn on power supply!
Connect cable terminals as required for the particular operating mode. To
prevent short circuits, you should seal unused cable ends!
As part of preparative actions, the LDM41E and LDM42E must be properly
installed in the designated working site, oriented onto the target and kept in a
stable position. The target to be measured should preferentially have a
homogeneous, bright surface.
Caution: Do not use any retro reflectors!
The alignment of the LDM41E and LDM42E is facilitated by a Laser beam13 that
is visible and can easily be turned on at the PC (e.g. command DT starting the
measurement and switch the Laser on, see 8.2).
7.1 Start up with RS232
For starting up, a PC with RS232 data interface or a USB converter for RS232
and a terminal program are required. We recommend the Windows program
LDMTOOL Version 4.0 or higher.

Figure 7 : Program LDMTool
7.2 Start up with Ethernet
The LDM41E and LDM42E come with a default IP address and subnet mask:
IP-Address: 192.168.0.51
Net mask: 255.255.0.0
Alternatively, there is a removable sticker with this information on the device.
Connect the LDM41E and LDM42E over a Switch or Hub to the network.
If the IP address of your PC does not start with 192.168 ... you have to unplug
the PC from the network and change the IP of your PC and establish a local
connection to the PC.
You can discover the IP address of your PC with Start | Run cmd (starting the
command input) and the then command ipconfig.
Page 22
Start up LDM41E and LDM42E Manual
Page 22 ASTECH GmbH
Use the program "EtherTool" by ASTECH and run "Search". Alternatively, start
a telnet client (Windows Telnet, putty or other via TCP/IP port 23) and
connecting you with specifies the IP of the LDM41E and LDM42E.
Figure 8 : Program EtherTool
After Telnet connection is established, you get by entering the "#" in the
configuration mode (see image above). By entering the number corresponding
to [Selection], you can change IP addresses and subnet mask.
Attention: The changed IP addresses and subnet mask is active after a
restart of the device! Then you must re-establish the Telnet
connection.
The configuration mode can be protected by a password. The password must
be at least 4 characters long. If no password characters are entered it will be
cleared.
Attention: Store the password secure and loss protected. The
configuration mode can call no longer without the password!

The LDM41E and LDM42E can be parameterized very easy with the PC. The PC
must be equipped with a serial interface RS232 and/or RS232 according to the
attached LDM41E and LDM42E. The use of USB to serially converters is also
possible. An optionally programming cable is necessary. On the PC a terminal
program must be installed (LDMTOOL or HyperTerminal). By selecting
ID[Enter] command, you may call up the menu with available setup commands
(DX[Enter] only LDM42E):
In preparation of a measurement so the sensor can be adapted by intelligent
parameterize optimally to the measuring conditions and the measuring task.
All valid settings will be preserved on turning the LDM41E and LDM42E off!
They can only be replaced with new value entries or changed back to their
standard values by running an initialization routine.
Command entries are not case-sensitive. This means that small and capital
lettering can be used for commands. Any command must be terminated by a
hexadecimal 0Dh (carriage return) character. Where decimal digits are to be
entered, they must be separated by period (2Eh).
For command parameter entries, one must distinguish between parameter
settings and parameter queries. Querying is achieved with a command in
simple format, e.g. (for alarm center parameters):
AC[Enter]
For parameter setting, a new value must be added after the command with no
delimitation sign in between, for example:
AC20.8[Enter]
In the given example, the alarm center will be set to 20.8.

Note: The LDM41PN and the LDM42PN are not equipped with an
analogue current output. Therefore the configuration commands for
the analogue output cannot be used for the LDM41-42PN. However,
they do ensure compatibility with the LDM41A andLDM42A (without
Profinet).

8.2 DT – distance tracking
Input parameter SA, SD, SE, SF, ST, OF
Output RS232/RS232, digital switching output, analog output
DT mode can be chosen for distance measurement of different kinds of
surfaces (varying reflectance). In this type of distance tracking mode, the
LDM41E and LDM42E uses internal algorithms to continuously evaluate the
quality of the Laser radiation signal that is coming back. This may cause longer
measuring times in the case of poor reflectance or sudden jumps in distance.
The minimum time to measure is 240 ms, the maximum time is 6 s. If the
measuring signal fails to reach a specified quality within six seconds, an error
message is output.
The time to measure may also be limited by setting the ST parameter to a
desired value. ESC stops the measurement.
8.3 DS – distance tracking (<7 m)
Input parameter SA, SD, SE, SF, ST, OF
Output RS232/RS422, digital switching output, analog output
Operation in DS mode makes sense where different types of surfaces have to
be measured at close range up to 7 m. Compared to DT measuring mode, it
allows a higher measurement rate. Within the range from 0.1 m to 0.5 m,
measuring accuracy is restricted (± 4 mm). Measuring time (time to measure)
can be limited via ST parameter settings.
ESC stops the measurement.
8.4 DW – distance tracking with target board (10 Hz)
Input parameter SA, SD, SE, SF, OF
Output RS232/RS422, digital switching output, analog output
DW mode performs at a steady measuring rate of 10 Hz. As a necessary
precondition for measured values to be stable, a white target board must be
placed at the selected object. There must be no sudden jumps in distance
greater than 16 cm within the measuring field!
ESC stops the measurement.

8.5 DX – distance tracking with target board (50 Hz)
Input parameter SA, SD, SE, SF, OF
Output RS232/RS422, digital switching output, analog output
DX mode performs at a steady measuring rate of 50 Hz (only LDM42). As a
necessary precondition for measured values to be stable, a white target board
must be placed at the selected object.
This measurement mode is intended in the first place for objects performing
homogeneous motion up to 4m/s. For higher rates of measurement,
preceding measured values will be included in the process to calculate a
currently measured value. There must be no sudden jumps in distance greater
than 16 cm within the measuring field!
Caution: To prevent transmission problems, please use 9600 baud
as the minimal baud rate for DX Mode!
8.6 DF – distance measurement with external trigger
14
Input parameter SD, SE, SF, ST, OF, TD, ST, SA, RM
Output RS232/RS232, digital switching output, analog output
DF mode allows a measurement that is triggered by an external trigger pulse.
Initially, after selecting this mode, the operator does not receive any response.
As soon as the trigger pulse has been detected, the LDM41E and LDM42E will
send data and switches to digital and/or analog output.
Settings for trigger delay (delay) and trigger slope can be defined via
parameter TD (see 8.20 TDx y – display/set trigger delay trigger level).
With ST=1 the maximum trigger frequency should not exceed 3.5 Hz.

Input parameter SD, SE, SF, ST, OF
Output RS232/RS232, digital switching output, analog output
DM mode triggers a single measurement (single shot)
8.8 TP – internal temperature [°C]
TP queries the value of the inner LDM41E and LDM42E temperature.
Note: In tracking mode, the inner temperature may exceed the surrounding
temperature level by as much as 10 K.
8.9 SA – display/set average value [1..20]
SA allows you to calculate a floating average value from 1 to 20 measured
values. Calculation is based on this formula:
Average value:
Standard setting is 1 (no average).
8.10 SD – display/set display format [d/h/s}]
SD selects the output format of measured value data. There are three modes
available:

SD affects all commands that output a distance value.
An output value is calculated from a given measured distance value (in mm),
multiplied by the scale factor SF.
Page 28
Commands and Parameter LDM41E and LDM42E Manual
Page 28 ASTECH GmbH
Negative distance values are output in two’s complement notation.
The value for the signal quality varies between 0 and 1024. 0 means a bad
signal quality while 1024 indicates a very good signal quality.
Examples:
Distance = 4,996 m, SF1
dec: 004.996<CR><LF>

dec+sig: 049.960_000005<CR><LF>
Error case
dec/hex: E15<CR><LF>
(see 11 Error Codes)
8.11 ST – display/set measure time [0..25]
Measuring time is directly conditional on the selected measuring mode. As a
general rule, one may say: the poorer the reflectance of the surface of a
particular target, the more time the LDM41E and LDM42E will require to
determine the distance with specified accuracy. For example, if error message
E15 is output because of poor reflectance and insufficient time to measure,
this latter setting must be increased.
Page 29
LDM41E and LDM42E Manual Commands and Parameter
ASTECH GmbH Page 29
The available value range for measuring time is 0 to 25. Basically, the greater
the time setting is the more time will be available for measurement and the
lower the resulting measuring rate.
An exception there from is zero-value. In this case, the LDM41E and LDM42E
automatically picks the smallest possible time value for measurement!
The LDM41E and LDM42E comes factory-set with ST = 0.
ST is effective in the DT, DF and DM mode of operation.
The measuring time setting option can also be used to modify the measuring
rate, for example, in order to restrict the data volume or for synchronization
purposes. Measuring time can only be set as an approximate value, because
the underlying principle of measurement is subject to certain variances that
cannot be accounted for:
DT measuring mode → measuring time= ST x 240 ms (except ST = 0)
DS measuring mode → measuring time = ST x 150 ms (except ST = 0)
Example:
The target distance is 25 m, but the target’s reflectance is not ideal. With a
measuring time setting of ST 2, E15 will be output following measurement.
The user must increase the time (ST > 2) or set auto (ST 0) to measure in this
case!
One should work in DW or DX measuring mode where stable
measuring times are required.
8.12 SF – display/set scale factor
SF multiplies a calculated distance value with a user-selectable factor for
changes in resolution or outputs in a different unit of measure. The scale
factor may also be negative. Standard setting is 1.
The scale factor influence the output of measurement results, Offset (OF),
Alarm Centre (AC), Alarm Hysteresis (AH), Range Begin (RB) and Range End
(RE)!

8.13 SE – display/set error mode [0/1/2]
SE (error mode) allows you to configure the behavior of the digital switching
output (alarm) and/or the analog output following an error message (E15, E16,
E17). Depending on the particular LDM41E and LDM42E application
environment, error messages have to be handled in different ways.
Available setting options are 0, 1 and 2 with the following effects in the case of
an error:

8.14 AC – display set ALARM center
AC sets the beginning of the distance range, for which the switching output
will be turned active. The length of this active range can be set using the AW
parameter.
Page 31
LDM41E and LDM42E Manual Commands and Parameter
ASTECH GmbH Page 31
AC must be selected in keeping with the currently set SF scale factor (see 9.4
Digital Switching Output (Alarm)).
8.15 AH – display/set ALARM hysteresis
AH allows you to make parameter settings for the switching hysteresis at the
beginning and the end point of the active range of the switching output.
AH must be selected so it is properly matched to the currently valid scale
factor (SF).
The mathematical sign of AH can be used to set an active state logic level:
Positive sign (“+”): active range is HIGH-active.
Negative sign (“-“): active range is LOW-active.
No sign setting means positively-signed (see 9.4 Digital Switching Output
(Alarm)).
8.16 AW – display/set ALARM width
AW sets the length of the active range, beginning at AC.
AW settings must be made in agreement with the currently valid SF scale
factor.
AW is always equal or greater than “0” (zero).
AW is always equal or greater than |AH| (the amount of AH).
Standard setting is 100000 – means off.
8.17 HO – display/set Temperature for heating on
15
HO displays/sets the temperature value at which the internal heating is
switched on. The values can be varied between -40°C and 70°C.
Standard setting is 3°C.

8.18 HF – display/set Temperature for heating off
15
HF displays/sets the temperature value at which the internal heating is
switched off. The values can be varied between -40°C and 70°C. Standard
setting is 12°C.
8.19 RMx y z – display/set remove measurement
Standard setting: 0 0 0
RM is intended to facilitate settings for a range of expected distance values.
Values which are found to be outside of this expected range will be corrected
until matching the most recently valid measured values.
RM is only effective in DT mode.
It consists of three parameters which are separated by space (20h).
x designates the number of preceding measured values that will be
evaluated in the case of non-conforming measurement. A maximum
of ten preceding measured values can be evaluated.
y defines the range of permissible values. If this range is exceeded in
negative or positive direction, the respective measured value will be
corrected accordingly.
z stands for the number of values that are out of the permissible value
range (out of tolerance values). In the event of out-of-tolerance
values arriving in succession, the most recently corrected value will
be included in the correction process for the next out-of-tolerance
value. The maximum allowed number of out-of-tolerance values is
100.
Important: The use of RM parameter settings should be restricted
to suitable applications only. Improper use of the parameter may
create safety hazards!

8.20 TDx y – display/set trigger delay trigger level
16
TD is only intended for the configuration of the remote trigger input (see 8.6
DF – distance measurement with external trigger).
TD consists of two sub parameters, of the actual delay value, i.e. the delay
time, and the trigger level.
Trigger delay corresponds to the time from arrival of the trigger signal to the
starting point of a measurement. It may be set to any value between 0 and
9999 ms. With the help of the trigger level one may define if measurement is
to begin on a rising or a falling pulse slope.
Trigger delay and trigger level must be separated by space (20h) in the entry
line. Standard setting: 0 0.
x Delay time between trigger signal and start of measurement, delay
can be set from 0 to 9999 ms.
y 0 for HIGH → LOW-slope
1 for LOW → HIGH-slope
Example:
TD1000_0[Enter]
In the given example, the delay has been set to 1000 ms and the trigger slope
to "rising" (LOW-to-HIGH transition)
8.21 TMx y – display/set trigger mode trigger level
17
TM provides parameter setting options for the auto-start trigger function
which allows external triggering of the auto-start command that was set via
parameter AS. Triggering is accomplished via the external trigger input. All
starting modes which are selectable via AS can be launched and stopped by
external triggering. These are: DS/DT/DW/DX/DF/DM/TP/LO/ID.
TM consists of two parameters which are separated by space (20h).

8.22 BR – display/set baud rate [2400..38400]
Available baud rate settings are: 2400, 4800, 9600, 19200, 38400. Faulty
entries will be rounded to the nearest baud rate. A fixed data format of eight
data bits, with no parity and one stop bit is used. Standard setting is 9600

8.23 AS – display/set autostart command
AS (auto start) defines which function will be carried out when power
becomes available to the LDM41E and LDM42E.
Possible entries are those delivering a measured value on the output side, an
ID command or the command for turning the Laser on (LO).
For example, if ASDT has been parameterized, the LDM41E and LDM42E will
begin with distance tracking on turning on power.
8.24 OF – display/set distance offset
With the help of OF (offset) the user may define a zero-point for his/her
application. For details about the position of the module’s zero-point, refer to
section 4. OF has to match the current valid scale factor setting (SF).
OF may also take on negative values. Standard setting is0
8.25 SO – set current distance to offset
SO performs a distance measurement and saves the measured reading as an
offset value with inverted mathematical sign (OF).

Ethernet is the most widely used standard for wired networks. The LDM41E
and LDM42E realized Fast Ethernet with 100 MBit / s.
The data is transmitted using Telnet (port 23). This must be established with a
Telnet client connects to the Telnet server in the LDM41E and LDM42E. The
program EtherTool provides an integrated telnet client.
The commands are described in chapter 8 starting page23. The data output
format is determined by parameter SD (display format), see page 27.

9.2 Serial Interface RS232
Initially, RS232 communication interfaces purely functioned as PC
communication ports. They have become the established standard tool for
serial data transmission over short cable lengths. With greater transmission
lengths, the interface is highly susceptible to interferences, notably, in the
vicinity of strong electromagnetic noise emitters.
Therefore, it should only be used for LDM41E and LDM42E configuration.
The commands of the serial interface are described in chapter 8 starting page
23. The data output format is determined by parameter SD (display format),
see page 27.
9.3 Output Format Ethernet and RS232
The output format on the serial interface is selected by the command SD.
There are three modes available:

SD affects all commands that output a distance value.
An output value is calculated from a given measured distance value (in mm),
multiplied by the scale factor SF.
Negative distance values are output in two’s complement notation.
The value for the signal quality varies between 0 and 1024. 0 means a bad
signal quality while 1024 indicates a very good signal quality.

9.4 Digital Switching Output (Alarm)
With the help of a user-selectable distance threshold, the switching output
can be set to monitor objects or conditions for positive or negative overstep.
For example, using the digital switching output, an object which was selected
for measurement can be monitored for excision of a threshold value. To do
this, parameter settings for a measurement window are required. Settings for
this window can be made via the three parameters: Alarm Center (AC), Alarm
Hysteresis (AH) and Alarm Width. The range which will be subject to
monitoring begins at AC and ends at AC+AW. Switching transitions can be set
via parameter AH.
The logic state of the switching output follows from the mathematical sign of
AH.
In the case of a positive AH, the output switches
- with increasing distance:
from LOW to HIGH if the distance is greater than (AC ±AH/2)
from HIGH to LOW if the distance is greater than (AC+AW+AH/2)
- with decreasing distance:
from LOW to HIGH if the distance is smaller than (AC +AW-AH/2)
from HIGH to LOW the distance is smaller than (AC-AH/2)
Page 41
LDM41E and LDM42E Manual Interface Connection
ASTECH GmbH Page 41
In the case of a negative AH, the output switching pattern will be inverse.

9.5 Trigger Input
19
The trigger input is intended for triggering a distance measurement with an
external signal that is applied as a voltage pulse between 3 V and 20 V. This
input is used only in trigger mode DF (DF – distance measurement with
external trigger)!
It is for the user to specify a desired delay time and a pulse slope to be
selected for synchronization (see 8.20, TDx y – display/set trigger delay trigger
level). The distance measurement will always be started with a delay of 5 ms
in addition with the programmed trigger delay time.
Having done this, the LDM41E and LDM42E has to be switched to trigger
mode (see 8.6, DF – distance measurement with external trigger).
