A. Introduction
1. Basics of the LMS System
The Laser Measurement System LMS 200, LMS
220, LMS 211, LMS 221, LMS 291 is based on a
time-of-flight measurement principle (Laser Radar).
A single Laser pulse is sent out and reflected by an
object surface within the range of the sensor. The
elapsed time between emission and reception of the
Laser pulse serves to calculate the distance between
object and LMS.
Via a integrated rotating mirror the Laser pulses
sweep a radial range in front of the LMS unit. A 2-
dimensional measurement field / detection area is
defined.
(For further details please refer to the Technical Description
Laser Measurement Systems SICK order no.: 8008970)
Main benefits of this measurement principle are:
•Detection of objects independent of object color
and surface structure
•Reliable detection of object presence
The Laser Measurement System LMS offers a
solution for a large range of applications:
•Determining the volumes of objects (measuring
packages, pallets, containers)
•Determining the position of objects (pallets,
containers, transport vessels)
•Collision prevention for vehicles or cranes
•Controlling docking processes (positioning)
•Classification of objects (vehicle detection, camera trigger)
•Process automation (e.g. calander rollers)
•Checking overhang/area monitoring in automated multi-storey car parks
•Determining the volumes or contours of bulk materials
•Monitoring open spaces for building security (facades, grounds, shafts)
•... and many more

•Suitable brackets, mounting.
A laptop or desktop computer serves as user interface with the LMS unit. The computer is
connected via a serial interface:
•RS232 interface (up to 10 m cable length) (standard COM1 or COM2 in most computers)
•RS422 interface (up to 1200 m cable length) (special interface card required)
In case a high-speed data transmission is required, SICK offers special interface boards for 500
kBaud transmission rate. For details and information please refer to section D.2.

2. Power supply
The LMS unit is supplied with 24 V DC +/- 15%. Depending on the length of the power supply
cable, the power supply needs to provide sufficient current.
Due to the LMS models, connection diagrams are different for LMS200/LMS291 and
LMS220/211/221.

3. Serial interface for data exchange
For data exchange in measuring tasks, the LMS is equipped with a serial RS 232 / RS 422
interface.
By setting a jumper, RS422 or RS232 can be enabled. Default setting is RS232.

Note: As there is no standard for RS422 connector pinning, please check the signal
assignments of your RS422 interface card to the respective PINs. Refer to the
documentation of your RS422 interface board manufacturer.
In case of deviations, change the cable assignments accordingly.
For selection of the RS422, there needs to be a jumper connection between between
PINs 7 and 8 on the LMS side inside the cable connector.
PINs 2 and 3 are crossed in the cable, PINs 1 and 4 are crossed in the cable. It is
recommended to use twisted pair cables for RS422 connections.
2. For LMS 211 / LMS 220 / LMS 221
Note: For selection of the RS422, there needs to be a jumper connection between between
PINs 3 and 11 on the LMS side in the cable connector.
PINs 2 and 3 are crossed in the cable, PINs 1 and 4 are crossed in the cable. It is
recommended to use twisted pair cables for RS422 connections.

C. Communication via MST Demo
1. Principle of MST-Demo
The MST Demo Tool is made for two main purposes. Primarily it demonstrates what can be done
with the software package MST 200 and what functions are available for custom software
development. On the other hand it is a tool for quick and easy recording of scans for a
preliminary data evaluation. The feasibility of the LMS sensor as a data source for a specific
application can be evaluated with this tool.
2. Installation of MST
MST is delivered as a ZIP file. Please create a dedicated MST home directory on your harddrive.
After unpacking the ZIP file into the home directory, you get the following file structure.
By starting MSTDemo.exe you will get the MST start screen with an active menu (Start | Options).

2. Communication LMS to PC with MST
MST Provides a simple data connection. The Hardware connection between PC and LMS is
shown in section B3.
Please select Options in the start window and set your connection parameters.
Note: Always select 9600Bd . MST will automatically use the highest Baud rate possible
when started.
The Software is now ready.
Within the Start button you will have several applications which can be started.
For every application MST_Demo will create a configuration file in the MST home directory. This
configuration file is a text file and can be edited with every editor.
In this quick start manual the application Record LMS scan data and Play back LMS scan data
are discussed. The other applications follow the same idea by principle.
