1.1
Overview Safety
Safety Instructions
LPR systems are purely tracking and assistance systems. They
therefore do not satisfy the safety class 3 requirements and must not be
used as standalone systems in safety-critical applications, such as
automation or anti-collision.
Follow the safety instructions in the operating instructions for the device
and the additional documentation!
Keep these safety instructions and other documents together with the device.
1.2
Installation
All installation, repair and servicing work must be carried out by qualified
and trained technicians!
When the system is mounted on fixed tubes the necessary measures to
prevent slippage of the system must be taken
1.3
Repairs
Repairs of the device must be carried out by authorized technicians.
Unauthorized opening and incorrect repairs could result in severe
danger to the user (danger of electric shock, radiated energy, fire
hazard).
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

Product Documentation
Overview of the LPR-1DHP system
An LPR-1DHP system consists of two units named BS and TS that conduct the
measurements. One unit (BS) initiates the measurement and the second unit (TS) replies.
Both units are shipped in a pre-configured set. Unit BS1 is configured to measure with TS1,
BS2 with TS2 and so on. The distance values are only available on the unit labeled BS.
Consequently, the unit BS must be mounted at the position where the distance values are
required, e.g. on the crane-bridge. Figure 1 shows the complete system including mounting
bracket for mounting on tubes.

Mounting

When the system is mounted on fixed tubes the necessary
measures to prevent slippage of the system must be taken

All installation, repair and servicing work must be carried out by
qualified and trained technicians!
A lot of the terms used in the following description are explained in
Figure 1 and Figure 3.
The LPR-1DHP station (front and rear element) is delivered pre-mounted, and with a
separate mounting bracket. Figure 1 shows the complete system including mounting bracket.
The mounting bracket must be mounted with a separte pipe clamp on a pipe. For mounting
the system please proceed as follows:
 Please use a torx wrench type T25 to remove the front element A from the rear element
B by loosening of the mounting screws (A2). If necessary you can disconnect the
ethernet cable (B5) from the front element (A3) to be more flexible.
 Insert the power supply cable in the cable feedthrough (B3) and connect it to the power
supply terminal (A4) on the rear element (A); siehe Figure 6.
 Reinsert the Ethernet connector (B5) of the rear element (B) into the connector (A3) of
front element (A). Mount the front element (A) on the rear element (B). It might be
necessary to tighten the inserted power cable.
 Fix the front element on the rear element with the housing screws (A2) using a torx
wrench T25.
 Carefully tighten the cable feedthrough with flat wrench SW19.
 Mount the mounting bracket (C) on a pipe installed at a suitable place. Do not tighten the
screws of the pipe-clamp yet, the system must be aligned first.
 Mount the LPR-1DHP station in the mounting bracket (C). When tightening the screws in
the mounting slot (C1) make sure that you can still align the system unit.
 Carefully align both units. To do so, it is recommended to use a laser level fitted into the
alignment aid (B1).
 Finally fix the system by tightening the screws of the mounting bracket and the pipe
clamp. Flat wrench SW 11 and 13 are required.

Avoid entry of foreign objects or liquids into the system unit,
especially on the PCB stack of front element (A) or within rear

Protocol XP Description for TCP/IP and RS232
8.1
General Description
This protocol is the interface between a LPR-1DHP 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 19200 baud.
8.1.1
Structure of Data Packet
The binary protocol XP was originally designed for transmission over RS232 interfaces.
When the protocol is used 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.
START
0x7e
TYPE
1 byte
1 byte
DATA
CRC
END
0x7f
2 byte
1 byte
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. Therefore up to 256 different types can be
defined . The TYPE-field is followed by 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 and END data field.
All multi-byte integers (e.g. CRC field) are encoded in Network-Byte-Order (Big Endian).
8.1.2
Byte Stuffing
The two symbols 0x7E and 0x7F are unique for START and STOP-fields. If these symbols
occur 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 XP Description for TCP/IP and RS232
Copyright © Symeo GmbH 2010
Seite 37 von 40
SYMEO Local Positioning Radar System
LPR-1DHP
Product Documentation
Byte stuffing is deactivated for the fixed frame protocol (compare chapter
8.3).
8.1.3
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-1DHP system
the byte stuffing must be resolved to get the original symbol. Then the CRC is updated with
the original symbol.

Binary protocol XP over TCP/IP: Fixed Frame Protocol
If the LPR-1DHP 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 8.1.2.) Byte stuffing causes a different protocol length.
For the fixed frame protocol each LPR-1DHP 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-1DHP unit.
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.

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

converter 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. 89 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 is always written in data bytes 12-15
8.3.2
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 (89 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.
