1.4 Transport and Storage
Use the original packaging or other suitable packaging for returns and
whenever the system is to be transported. This ensures protection from
crushing, impacts, moisture and electrostatic discharge.
During setup and before operation, refer to the instructions for
environmental conditions included in the operating instructions for the
device.
Route the wires in such a way that they do not cause a hazard and are not
damaged. When connecting the wires, refer to the corresponding
instructions in the operating instructions for the device.
Do not drop the device and do not expose it to strong vibrations.
1.5 Power Supply
A safety-inspected power cable that satisfies the regulations of the country
of use is required for the device. Devices with metal housings must only be
connected to a grounded, shock proof socket.
The device must not be operated unless the nominal voltage of the device
matches the local supply voltage. Check the supply voltage of the device in
stationary devices.
Connecting and disconnecting wires refer to the instructions in the
operating instructions for the device.
Do not use any damaged wires (damaged insulation, exposed wires). A
faulty wire poses a risk of electric shock or fire hazard.
1.6 Setup and Operation
During installation, make sure that no objects or fluids get inside the device
(risk of electric shock, short circuit).
In emergencies (e. g. if there is damage to the housing, control elements or
the mains cable, if fluids or foreign bodies have infiltrated the equipment),
switch off the power supply to the device immediately and notify your
SYMEO Service.
Protect the contacts of all of the device's sockets and plugs from static
electricity. Do not touch the contacts. If it is ever necessary to touch the
contacts, take the following precautionary measures: Touch a grounded
object or carry a ground strap before touching the contacts. This will divert
static charges.
Proper operation (in accordance with IEC60950/EN60950) of the device is
only assured if the housing and integral covers for mounting slots are fully
installed (electric shock, cooling, fire protection, noise suppression). If

2 System Description
2.1 System architecture
SYMEO Industrial LPR® is a system for contactless, real-time determination of distances and
positions.
LPR® 1D is a distance measurement system which is particularly well suited for use in very
harsh, industrial environments, in which other systems such as mechanical rotary encoders
or lasers cannot function for long periods.
All devices have a unique identifier, via which they are actuated. In order to measure the
signal transit time and thus also a corresponding distance, the two devices involved are
time-synchronized (with accuracy in the picoseconds range).
LPR® units use the same frequency band and the same hardware for communicating as for
measuring distance. This means that no external WLAN or cable networks are needed for
transmitting measurement values and other reference data.

2.3 System Configuration
The LPR® 1D system consists of two, three, four or five LPR® units. Each of these units can
be configured either as a transponder or as a base station. A system consists of exactly one
LPR® unit configured as a transponder and between one and four LPR® units configured as
base stations.
For pure 1D distance measurement two units are required and are arranged as shown in
Figure 3. The distance information is available at both stations.

Besides the distance information, smaller volumes of user data can also be passed between
the units. These are fed in on the serial port of a unit and output in corresponding manner on
the other side.
Each unit consists of a basic unit, corresponding antenna cable, antenna, as well as power
supply and ports.
Further options for arranging LPR® units are described in the section 2.6 "Application
Examples".
2.4 System Design
Each LPR® 1D station has parameters to provide an explicit allocation to a system and also
to ensure the functionality of a system. These parameters are explained in the following:
2.4.1 Station-ID (SID)
Each station has an explicit Identification Number in one system. If using more than one
LPR® 1D systems in your environment same station numbers could be used. BUT: In one
system all station numbers are different.
A system consists at least of 2 stations, at most of 5 stations. The first station has the station
number 1 (SID 1), die second station has the station number 2 (SID 2), etc.
Station 1 (SID 1) is the LPR® Transponder, also known as the coordinator of the system.
Stations 2 5 (SID 2-5) are LPR® Base Stations. A transponder (SID 1) can only measure
with a base station (SID 2 SID 5) and vice versa, but NEVER with another transponder or
a base station with another base station. But the transponder (coordinator) can measure with
up to 4 base stations.
Keep in mind:

Base Station
The hardware of a transponder and base station looks like the same. The
only difference is the configuration software. The transponder organizes
the measurements. It allocates time slots to the base stations to identify
when these stations are allowed to start with a measurement.
2.4.2 Group-ID (GID)
A system is identified clearly by its group number. All stations in one system have the same
group number. If there is used a second, a third or more systems in your environment, all
additional systems must have then a different group number (see Figure 5).
2.4.3 FSK Channel (FSK)
The measurement of the round trip of flight (RTOF) happens in a frequency band width of
5,725 to 5,875 GHz. In this band width the LPR® system gets a frequency channel. 18
frequency channels are available. All stations in one LPR® systems have the same
frequency channel.
If there are more LPR® systems in your environment each further LPR®
system has another frequency channel (see Figure 5).
If you commission the system with the LPR® commissioning tool LPR® 1D
Wizard you cannot choose the frequency channel. The frequency channel
is linked to a group ID. Therefore it is really important to use different group
IDs for different LPR® systems.

2.5 Mode of Operation of the System
The distance is determined by measuring the transit time of radio signals. For this, the
transponder unit first sends a communication packet to the base station that is to carry out
the measurement. The station that is addressed in this way sends a response sequence and
a special, wideband response signal which is ideal for making distance measurements. The
transponder synchronizes itself with this signal and after a precisely known time replies in
highly synchronized manner with exactly the same signal. The base station receives this
signal and uses the signal transit time to determine its distance from the transponder.
The distance can be output after the measurement by any of the units participating. As an
option, if the distance falls below a given value, a switch (dry contact) can be actuated to
trigger a warning signal, for example.

System Description

Page 15 of 87
Besides distance measurement, the system's communication can be used for transmitting
user data in the intervals between measurements. Transmission is asynchronous, i.e. the
data is requested and transmitted when the measurement has been completed. To transmit
data over the system, first a send data request is sent by the LPR® unit to the user. Then the
user data is received and transmitted to the second LPR® station. The data channel has a
channel capacity of 8byte/measurement cycle. This means, the overall capacity depends on
the chosen measurement frequency. I.e. if a measurement frequency of 10Hz is chosen, the
capacity is 80 byte/s
2.6 Application Examples
Figure 3 in shows the simplest arrangement of LPR® units (LPR® 1DX). This is used for
measuring the distance between two LPR® units. The abbreviation means distance
measurement without positioning.
Some more complex arrangements are illustrated in the following text.
2.6.1 Redundant arrangement (2xLPR-1DX)
For reasons of operational safety, it may be necessary to combine two systems in a
redundant arrangement. Figure 4 shows two base stations and two transponders installed in
a redundant arrangement on two crane bridges. Each base station communicates with the
opposite transponder. Both systems measure independently from each other. After the
measurement, the distance from the respective partner can be output at each of the
participating stations. Optionally, a switching contact may also be actuated depending on the
distance, e.g., to trigger a warning signal for example if the crane bridges come too close to
one another and there is a danger that they may collide.
If more than one LPR® system is used, each system has its own group ID
and its own frequency channel. So both systems do not disturb each other.

2.6.2 Positioning of Crane Crab (LPR® 1DP2)
In order to determine positions in two dimensions (x-y coordinates), three LPR® units can be
arranged in an L-shape (see Figure 7). In this case, the unit that is configured as the
transponder (station 1) is equipped with 2 antennas. This unit measures against the first
base station (station 2) with the first antenna, and against the second base station (station 3)
with the other antenna, for example. In this way, the position of a crane crab can be
determined, for example.

2.6.3 Positioning of 2 Cranes on two Runways (LPR® 1DP)
The Y-shaped arrangement can be used to determine the position of two cranes on different
crane runways, for example. In the arrangement shown in Figure 8, the transponder unit
(station 1) is equipped with two antennas. One base station (station 2 and station 3) is
installed on each of the two cranes. The two antennas are secured to the wall at the same
height as the respective base stations installed on the cranes. In this way, the distance of
both cranes from the wall can be calculated. By comparing these two distances, a warning
may be outpu

4 Installation
4.1 Installation of LPR® Station Design Compact Station
4.1.1 Important Instructions for Installation
During Installation, the Compact Station has to be opened. Therefore it is
important to avoid ingress of moisture, dust or any particles into the
housing during the installation process. Make sure that there is enough
room for the connectors, and particularly that the antenna cable is
accessible; pay attention to the permitted bending radius (center of radius
to cable core) for standard cables of 10,5cm (for multiple bending under
mechanical load) and 4cm (unloaded and static bending).
The Compact Station should preferably be installed so that the connecting
sockets point downwards. In this way, the connections are protected from
rain and dust.
4.1.2 Installation
To install the Compact Station, you require
4 round head M6 x 30 screws (at least).
Check the position of the station on the device on which the Compact Station is to be
installed (e.g. a crane bridge). Bear in mind the installation instructions listed above.
Drill holes in the device on which the Compact Station is to be installed. Drill-hole
distances: 11 cm wide, 24 cm high (see figure 7).
Open the Compact Station: With a Phillips screwdriver (Size 0), loosen the top four
screws of the Compact Station lid.
Screw the Compact Station tightly to the device. The installation holes shown in figure 2
are provided for this purpose. Check that the station is mounted securely.
Close the station: Place the cover of the Compact Station on top and fasten the cover
with the four screws. Make sure that the cover is securely attached to the housing.
Commission the Compact Station (see chapter "Base Station Initialization")
4.2 Installation of LPR® Antennas
4.2.1 Connecting and Wiring up the Antenna and Cable
Connect the antennas to the antenna port at the LPR® station.
When using several antennas, ensure that they are connected to the
correct ports.

When installing the cable, ensure that electrostatic charging does not occur.
Make sure that the cable is not kinked or trapped during installation. The minimum
bending radius must always be maintained. With the standard antenna cables delivered,
the minimum bending radius (center of radius to cable core) for standard cables is
10,5cm (for multiple bending under mechanical load) and 4cm (unloaded and static
bending). The cable must not be attached in a way that alters its cross-section. On
demand, cables with different flexibility characteristics are available.
The antenna plug must not be removed (e.g. for installation purposes) or repaired
because the specified electrical properties can only be achieved with mechanical
installation assistance.
When installing the antenna cable, ensure that the screw connection is seated properly.
The antenna cable plugs should be finger-tightened before tightening with an appropriate
tool to no more than 1.3 Nm tightening torque.
4.2.2 Installing the Antenna(s)
The line of sight between the antennas on each unit must not be
obstructed. Therefore, when installing the antenna fixture, ensure that no
components are blocking the line of sight between the antennas. If
necessary, contact the SYMEO technical department.
Depending on the antenna type used, offsetting the corresponding
antennas (either vertically or horizontally) may degrade the signal strength
to the point that communication is lost. Accordingly, corresponding antenna
pairs should be installed with as little offset with respect to each other as
possible, and preferably none. If necessary, contact the SYMEO technical
department.
If you change the position of one antenna, this will affect the measurement
data that is output.

For installation of the Planar Antennas, it is important to keep the same
orientation of polarization for corresponding antennas (see Figure 17).
Figure 17: Backside of 23 dBi Planar Antenna
Install the antenna fixture according to the accompanying operating instructions.
Secure the antenna in the fixture.
Connect the antenna to the antenna cable.
4.2.3 Fresnel zone
The area for radio transmission between two antennas is called Fresnel zone. The main part
of energy is concentrated in the first Fresnel zone.
This area has to be free of any obstacles otherwise the signal is
interrupted or attenuated.
The first Fresnel zone can be calculated as follows:
is the wave length and the distance between the two antennas. For a frequency of 5.8
GHz a wave length of approx. 0.05 m is calculated. The maximum radius between the two
antennas is indicated with . For different distances the maximum radius is given in Figure
18.

4.2.4 Installation of Planar Antennas
Each antenna type has its own opening angle. To communicate with the
opposite antenna the relative antennas has to be located in the opening
angles of the opposite antennas.
Antennas have to be mounted without any offset (no difference in height and no offset
sideways). Make sure that the opening angle is symmetric to the relative direction of motion
(compare picture 1 vs. picture 2 in Figure 19).
If an offset is not inevitable the antennas have to be tilted (compare picture 3 vs. picture 4 in
Figure 19).
Notice: If the distance goes below a fixed distance it is possible that no
measurements take place any longer.

Data link has been established serially or via TCP/IP.
Once these prerequisites have been fulfilled you can connect the station either serially to a
PC or as an option (TCP/IP option) to the network and commission the LPR® 1D system.
How to do this is explained in the following chapter.
5.1.1 General
Commissioning is carried out via the serial port or the TCP/IP port depending on the LPR®
station model you have.
Each LPR® unit is equipped with the following interfaces:
An RS232 port for data transmission to downstream systems (PC, S7),
A second RS232 port for parameterization and software updates
Optionally, a TCP/IP port for data transmission and parameterization.
The radio interface at 5.8 GHz for data transmission, communication and measuring with
other LPR® units,
The two RS232 ports are incorporated in the Lumberg plug, the radio interface functions via
the system antenna.

In one LPR® system all distance data (binary data/ protocol) is available at each station. Also
if you have several stations in one system (crane bridge, crane crab, wall) you get the binary
data at each LPR® station in this system.
5.2 Connection to LPR® Station with TCP/IP Interface
With delivery the LPR® stations have the fixed IP-Address 192.168.1.99, if
no other IP-Address is labeled outside the LPR® station.
You can change the IP-Address of the LPR® Station via the web interface of the LPR®
Station.
To get a connection between your PC and the LPR® station it is maybe
neccessary to change the network parameters of your computer. Both units
must be located in the same network. That means in this example that the
first three numeric pads of both IP-addresses must be the same.
Disconnect your PC from the network. Connect the LPR® station and the computer with a
network cable. Open your network settings of your computer.

The interface RS232 is only available for station without TCP/IP interface. If
a RS232 interface for station with TCP/IP interface is desired, please
contact the Symeo Service.
The commissioning could either be done via the serial interface of the 8-pin Lumberg
connector (Figure 23) or the serial interface inside the box (Figure 25).
Consider the dependency of the maximum baud rate according to the cable
length:
15m: 19.200baud

7 Protocol Description Binary XP (1D messages)
7.1 General Description
This protocol describes the interface between a LPR®-B station and the user. The binary
protocol XP protocol provides information in high density. Its structure ensures a simple
implementation. The transfer is done in single data frames.
The interface for the binary protocol XP can either be a serial (RS232) interface or a TCP/IP
or UDP interface. The baudrate of the serial interface must be set to 115200 baud.
7.1.1 Direction of Data
The interface can be applied bidirectional. However certain data types are defined for one
direction. Furthermore it is only allowed to send data to a LPR®-B station after the LPR®-B
station has sent a send request (type 0x02). Table 1 shows an overview which data packets
can be applied in which direction.

Tab. 1: direction of data
Sending data to the LPR®-B station is only possible after receiving a send request (Type
0x02-to-LPR®-B
station. The LPR®-B can only handle one data packet from one user.
If nevertheless data is sent to the LPR®-B station without a previous send request, it can
result in a reboot of the LPR®-B station.
Per one send request the user can send only one data set to the LPR®-B station.
7.1.2 Structure of Data Packet
To apply the protocol on a RS232 interface each data packet starts and ends with a reserved
symbol. This reserved symbol cannot appear in the data stream.
Figure 1 shows the general structure of the data packet.
TYPE DATA
START
0x7e
1 byte 1 byte 1 byte
CRC
2 byte
END
0x7f
Figure 1: Structure of data the packet
The START and the STOP-field is in each data packet the reserved symbol 0x7e and 0x7f.
TYPE indicates the type of the data packet. There can be defined up to 256 different types.

Page 68 of 87
The TYPE-field is following the DATA-field. The DATA field contains the real data of the
packet of the type TYPE. The CRC-field contains a check sum. The check sum is applied to
all previous data fields except the START data field.
All multi byte integers (e.g. CRC field) are encoded in Network-Byte-Order (Big Endian). All
signed integers are encoded in two's complement representation.
7.1.3 Byte Stuffing
The two symbols 0x7E and 0x7F are unique for START and STOP-fields. If those symbols
occurs within any other field (TYPE, DATA or CRC), they must be replaced by the following
order:
original symbol
replaced by
0x7D
0x7D 0x5D
0x7E
0x7D 0x5E
0x7F
0x7D 0x5F
This byte stuffing scheme ensures that the receiver of the protocol can identify definitely the
START-field within a flow of data, even if the symbol of the start field occurs within the
DATA-field.
Example: If the symbol 0x7d is read, it must be cancelled. The following symbol must be
XOR combined with 0x20 to recreate the original symbol.
Remark: Byte stuffing is deactivated for the fixed frame protocol (compare chapter 7.3).
7.1.4 CRC
The CRC-16-IBM with polynomial x16+x15+x2+1 is used for the CRC. The CRC is calculated
over all data fields (TYPE and DATA), but not for the START and END field.
The CRC-calculation is only applied to the original symbols. The appropriate calculation for
coding must applied before byte stuffing. If receiving the data from the LPR®-B system the
byte stuffing must be reserved to get the original symbol. Then the CRC is updated with the
original symbol.

1) Any measurement is always executed by a LPR®-B base station, this means, the base station
measures its distance etc. towards a transponder unit. The source field always contains the address of
the LPR®-B base station. The destination field contains the address of the measured transponder.
Even if the data set is transferred further on to another unit (e.g. another transponder), the value of the
source and destination field is maintained.
2) The field antenna contains the antenna number of the base station as well as the antenna number
of the measured transponder. The 4 lower bits represent the antenna number of the base station

With the relay selection (bitmask) relays are selected which can be controlled. The relays that are
chosen within the Relay Selection bitmask will be switched according to the Relay Switch bitmask
Example: A Relay Selection value = 0x14hex = 00010100bin and a Relay Switch value = 0xFFhex =
11111111bin will switch relays 2 and 4 ON - the state of the other relays remains unchanged.
No acknowledgment of the relay switch command will be sent because this data frame can be
forwarded to other LPR®-B stations and thus no reception on the destination station is guaranteed. In
case of faulty data frame (e.g. invalid relays chosen or unknown destination address) the LPR®-B
station will print an error message.

7.3 TCP/IP option: Fixed Frame Protocol
If the LPR® station has a TCP/IP interface two options are available for the protocol. Either
you use the protocol as it is sent from the serial interface (with different data type lengths,
byte stuffing) or you use a fixed frame protocol.
In the first case the data symbols 0x7e und 0x7f (which are reserved for the START and
END field) are replaced (see chapter 7.1.3). Byte stuffing causes a different protocol length.
For the fixed frame protocol each LPR® data packet is filled up with zero bytes to a fixed
length of bytes (i.e. 87 bytes) before the data packet is sent. Byte stuffing does not occur.
The START and the END byte are still used but not clear anymore due to not applying byte
stuffing. The fixed length of the data packets can be set on the web-interface of the LPR®
unit.
For the fixed frame protocol the data packets which are sent to a LPR® unit has to be filled up
to a fixed length (i.e. 15 bytes). The START- and the END byte have to be occurred as well
and byte stuffing does not occur anymore. It is recommended to fill up the data packet with
zero bytes to facilitate a troubleshooting.
If TCP/IP is used the transmitted data have already a checksum. Therefore the checksum in
the protocol is not as important as for the serial interface. Two options for the fixed frame are
allowed by the protocol inverter for receiving data in a fixed frame. Either 0x0000 is sent as
the check sum to the LPR® unit. Then the protocol inverter is calculating the check sum itself.
Or another value (differing to 0x0000) is sent as the check sum. Then this check sum is
assumed to be the correct check sum. Otherwise the data packet is rejected.
7.3.1 Detailed description TCP Fixed-Frame Protocol
If a TCP fixed-frame protocol is used, a working TCP connection between the PC and the
LPR® unit has to be guaranteed. Depending on the configuration of the LPR® protocol
inverter either the connection to a port on the LPR® has to be initialized from the PC or the
LPR® unit is establishing a connection to a PC.
If the connection is established, the PC has to read the data from the LPR® in fixed data
length (i.e. 87 bytes). The first byte is always the START-byte and the second byte is always
the TYPE-byte. The relevance of the following data is depending on the data type. Because
no byte stuffing occurs the content for a special data type is always constant. For example
the measured velocity of the distance data (type 0x00) is always written in the 12.-15 data
byte.
Sending data from the PC to LPR® station, a fixed data length has to be chosen (i.e. 15
byte). The first byte (START byte: 0x7e) follow the TYPE-byte. The following data depends
on the chosen type, following by the CRC (correct CRC or 0x0000), following by the STOP
byte (0x7f). The data packed has to be filled up with zeros.
7.3.2 Detailed description UDP Fixed-Frame Protocol
If a UDP fixed frame protocol is used, the IP and the UDP port of the PC has to be
configured in the LPR® protocol inverter. The converter sends each data packet as a UDP
packet of a fixed length (87 byte) to the PC. Compared to the TCP fixed frame option the
UDP fixed frame does not verify if the data packed arrived.
The content is the same as for the TCP fixed frame protocol.

LPR-1D
Product Documentation
Protocol Description Binary XP (1D messages)
Copyright © Symeo GmbH 2010
Page 73 of 87
If data is sent to the LPR® unit the data has to be packed in a fixed data length (i.e. 15 bytes
as for TCP fixed frame option). This data packet is sent as UDP packet to the LPR® unit. The
port number of the receiver is the same as for the PC.
In general bidirectional data communication is not recommended for UDP due to loosing
singular data packets.
7.4 Remarks
7.4.1 LPR®-B Address
LPR®-B station addresses are completely defined by a 16 bit value:
15 11 10 1 0
group ID BBstation ID
BB Base station Bit:
Indicates, if the LPR®-B station is defined as a base station
or as a transponder (1=base station, 0=transponder)
group ID:
group ID of the station (1..1022)
station ID:
station ID of the station (0..30)
In multi cell applications, group ID is the cell ID of the cell.

8 Trouble Shooting
This chapter will assist you for troubleshooting. For debugging circumstances it might be
helpful to install a terminal program to analyze the system.
8.1 Programs
8.1.1 Terminal Program
A Terminal program is useful for analyzing the system. The recommended terminal program
is RealTerm. It is Open Source Software and can be downloaded from the webpage
http://sourceforge.net/projects/realterm. Install the program on your PC.
8.1.2 Command Window (only for LPR-B Station with TCP/IP interface)
The easiest way to check a connection between a LPR-B station with TCP/IP interface and
your PC/network is the command window. The command window is preinstalled in the
operating system Windows. Click on the window button Start Enter cmd and
click on OK.
8.1.3 Telnet (only for LPR-B station with TCP/IP interface)
A short way to check the functionality of the LPR-B station with TCP/IP interface is Telnet.
Telnet is preinstalled in the operating system Windows. Click on the window button Start
Enter telnet IP-address Port and click on OK. E.g. enter telnet 192.168.1.99 3045
to open the configuration port of the LPR-B station with IP-address 192.168.1.99 and the port
3045.
8.1.4 Browser (only for LPR-B station with TCP/IP interface)
A webbrowser is necessary to make all settings of the LPR-B station with TCP/IP interface.
You can make network settings as well as settings for the protocol.
8.1.5 Network Scanner (only for LPR-B station with TCP/IP interface)
A network scanner like the program SoftPerfect
(http://www.softperfect.com/products/networkscanner/) is for analyzing your network useful.
8.2 Hardware
The following additional hardware is useful:
Serial Cable less than 2 meters (if there is a LPR-B station without TCP/IP interface )
LAN-cable (if there is LPR-B station with TCP/IP interface)
USB -RS232 converter (if there is no COM-port at your computer)
8.3 Connection to the LPR-B station with RS232 interface
If you have a station without TCP/IP interface you only can connect your PC via the RS232
interface to the LPR-B station. For the connection you need a RS232 cable which should be
less than 2 meters. A longer cable cannot guarantee a trouble-free transmission of data
between the LPR-B station and the PC.

8.4 Connection inside the LPR-B station
To analyze the serial connection between your PC and the LPR-B station it is the best to
connect the serial cable inside the LPR-B station. Open the LPR-B station. Make sure that
you do not pollute anything inside the LPR-B station.
There are 4 serial ports for connection. One port is for the configuration of the LPR-B station
(S4: parameterization port) another one is the port for the distance data (S2: binary data).
Two other serial ports (S1 and S3) are not used for commissioning the system.

If you do not get access to the LPR-B station check if the port is open. The port for the
parameterization is 3045 per default. But it might be possible that you have changed it or did
not open it (see chapter 8.5.5).
8.5.5 Web Interface
-address of the LPR-B station but do not get data (either via the
parameterization port or the binary port or both ports) you have to check the settings on the
web page of the LPR-B station.
Open a web browser and enter the IP-address of the LPR-B station (i.e. http://192.168.1.99).
You get access to the LPR-B station. If you are
connected via HTTPS-connection, it might
appear to dialogue boxes which you have to
confirm with OK.
You see the Start-page of the LPR-B station.
Click on Settings.
You have to authorize yourself.

Scroll down to the section:
Serial-to-Ethernet:
Here you enter the connection type
for the parameterization port
(ttyAM1) and the binary port
(ttyAM2).
Both ports should be not disabled.
Choose the right connection type
and enter the data port. The data
port is per default 3045 for the
parameterization port and 3046 for
the binary port.

Reboot system
After the reboot try again to get access to the LPR-B station as described in chapter 8.5.4.
8.6 No Measurements
You can get data on two ports: Parameterization port (S4) which is useful for the setup of the
system and the Binary Port (S2) compare figure Figure 44). The binary port is necessary if
you want to use the distance data for a system behind the LPR-B system. You will then use
Binary protocol and have to check that the binary port provides proper measurements.
Check List:
1) You have access with the program RealTerm to all stations. (If pressing the button 1
the LPR-B configuration menu is shown.)
2) The antennas are connected to the right port of the LPR-B station.

3) If you use planar antennas the orientation of the antenna must be correct. A small
label on the backside of the antenna indicates the horizontal and vertical alignment.
4) For a distance measurement always two stations are involved. It has to be a
transponder unit and a base station unit. Make sure that never two base stations or
two transponders a measuring with each other.
5) Check if the binary port works. Open the program RealTerm. If connected to a LPR-B
station with TCP/IP interface open the binary port 3046: Enter for example
192.168.1.99:3046. The display should be set to Hex[spac

If no measurement appear something is wrong with the setup. Check the following:
1) If you use a USB stick then disconnect the stick.
2) If you have LPR-B station with TCP/IP interface you also can connect the serial cable
to the parameterization port (S4). It is not possible to send data to the LPR-B station
then but you can receive da
wrong with forwarding the data to the TCP/IP interface. Check the settings in the web
interface (compare chapter 8.5.5). Compare also the settings for the jumpers
(compare Figure 45
allocation on the left side (2 jumpers) only the binary port is available via TCP/IP. If
using the Jumper allocation for RS232 no data can be available at a TCP/IP interface
(normally the station then has no TCP/IP interface).
3) Check if jumpers are set correct:

If you use LPR-B stations with and without TCP/IP jumpers are set differently. To make the
parameterization via serial connection jumpers has to be changed (only the both lower
pictures are set for configuration the LPR-B station via the serial cable).
4) Overwrite the configuration with the program LPR 1D wizard for all stations.
