1 Overview
SYMEO Industrial Local Positioning Radar (LPR®) is a system for contactless, real-time
determination of distances between two devices by means of radio signals.
All components are integrated in one casing. The compact unit can therefore be mounted
very easily and operate maintenance-free, even under harsh conditions. Dust, fog, or similar
impacts do not influence the system.
The Local Positioning Radar System LPR®-1DXi consists of equal units, which are
configured with the software Symeo-Wizard (via Windows PC with USB connection):

2 System Description
2.1 Mode of Operation
The distance is determined by measuring the transit time of radio signals. One unit initiates
the measurement and the second unit replies.
With the software Symeo-Wizard (via Windows PC) the distances for adjustable switching
points are determined and transferred to the LPR®-1DXi device. Upon reaching a switching
threshold, on-board relays open dry contacts. Relays are available on both units. Remote
units can be configured via the built-in radio interface. Optional the distance reading is also
available on both of the units.
LPR®-1DXi 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 setting switching relays.

2.3 System Configuration
The LPR®-1DXi system consists of two LPR®-1DXi units. For distance measurement and
collision-avoidance, the two units are arranged as shown in Figure 2. The distance readings
and relays are available at both of the paired units.
Figure 2: LPR®-1DXi system
2.4 System Design
Each LPR® 1DXi unit 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:
Parameters may only be set with the commissioning tool Symeo Wizard as
described in chapter 5.4. Do not change parameters manually in the
configuration files.
2.4.1 Station-ID (SID)
Each unit has an explicit identification Number in one system. A system consists of 2 units.
The first unit has the station number 1 (SID 1), the second unit has the station number 2 (SID
2).
2.4.2 Group-ID (GID)
A pair of LPR®-1DXi units is identified clearly by its group number. The two units in one
system have the same group number. If there is used a second, a third or more system in
your environment, all additional systems must have a different group number.

Page 10 of 38
2.4.3 Frequency Channel
The measurement takes place in a frequency band width of 5,725 to 5,875 GHz. In this band
width a frequency channel is assigned to the LPR®-1DXi system. 30 different frequency
channels are available. Two units in one LPR®-1DXi system need the same frequency
channel.
If there are more LPR®-1DXi systems in your environment each further
LPR®-1DXi system needs different frequency channels. The frequency
channel is linked to the group ID. Therefore it is required to use different
group IDs for different LPR®-1DXi systems in the same environment. You
can set the group IDs with the commissioning tool LPR®-1DXi Symeo
Wizard (see chapter 5).

4.6 Installation Notes for Antennas
4.6.1 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
11.

4.6.2 Alignment of LPR®-1DXi Units
The LPR®-1DXi units with the integrated 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 12).
If an offset is not inevitable the units have to be tilted (compare picture 3 vs. picture 4 in
Figure 12).
Notice: If the distance goes below a fixed distance it is possible that no
measurements take place any longer.

Protocol Description

Page 32 of 38
6 Protocol Description
6.1 General Description
This protocol describes the interface between a LPR®-1DXi unit and the user. The binary
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 is a serial (RS232) interface. The data rate can be
programmed to standard values (115200, 38400, 19200, 9600 baud). If a low data rate is
chosen the measurement rate of the LPR®-1DXi system may be adapted.
6.1.1 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 38 shows the general structure of the data packet.
TYPE DATA
START
0x7e
1 byte 1 byte 1 byte
CRC
2 byte
END
0x7f
Figure 38: Structure of the data 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.
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).
6.1.2 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.

Protocol Description

Page 33 of 38
6.1.3 CRC
The CRC-16-IBM with polynomial x16+x15+x2+1 is used for the checksum. The checksum is
calculated over all data fields (TYPE and DATA), but not for the START and END field.
The checksum-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®-1DXi system
the byte stuffing must be reserved to get the original symbol. Then the checksum is updated
with the original symbol.
