SYMEO Local Positioning Radar System LPR-1DXi Product Documentation Overview Copyright © Symeo GmbH 2009 Page 5 of 33 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 station 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 stations, which are configured with the free software Symeo-Wizard (via Windows PC): Figure 1 – LPR-1DXi station The LPR-1DXi station has different interfaces. The unit has IP65 protection class. Overview of Interfaces Power Supply 10-36 Volt via terminal block inside casing USB Parameter setting with Symeo Wizard (for Windows PC) Relays 7 dry contact relays via terminal block inside casing RS232 Distance reading via terminal block inside casing 1.1 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 this documentation! Keep these safety instructions and other documents together with the device.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation Overview Copyright © Symeo GmbH 2009 Page 6 of 33 1.2 Installation All installation, repair and servicing work must be carried out by qualified and trained technicians! 1.3 Repairs Repairs to 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 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. When 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.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation Overview Copyright © Symeo GmbH 2009 Page 7 of 33 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 necessary, refer to the corresponding instructions in the operating instructions for the device. In the case of high outside temperatures and intense, direct solar radiation or other radiant heat, it may be necessary to provide a sun or heat shield. 1.7 System Extensions and Accessories Data links to peripheral devices must be provided with adequate shielding. The warranty shall be voided if you cause defects to the device by installing or exchanging system extensions. 1.8 Additional Instructions The LPR-1DXi unit must not be opened except for installation. The LPR-1DXi unit contains no serviceable components. When opening, ensure that no fluid gets into the housing. When sealing the station, ensure that the seal is included in the cover and that the LPR-1DXi unit is completely closed. Otherwise, moisture can penetrate the station and damage it. Please take note of the safety and operating instructions in the operating instructions for the system in which you want to install the component.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation System Description Copyright © Symeo GmbH 2009 Page 8 of 33 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. 2.2 Technical Data Overview: Technical Data Frequency range 5.725-5.875 GHz, ISM band Transmitting power Max. 0.025 W / 14 dBm Positive signal control to opposite unit up to 1800 m Switch thresholds /distance reading 0 to 120 m (option – extended distance reading 0 to 500 m) Distance output 0,5 m increments (option – higher resolution: up to ± 5 cm *1) Repeat rate Up to 30 Hz Power supply 10-36 V DC Power consumption 6 W Ambient temperature -40°C to +75°C Protection class IP 65 Casing dimensions 190 x 190 x 80 mm (without supplied mounting bracket) Interfaces USB for parameter setting with Symeo Wizard (for Win PC); Serial RS 232 with binary protocol (terminal block inside casing); 7x dry contact relays (terminal block inside casing), each max. 2500VA / 300 W, max. 60 VDC, max. 10 A Compliance CE mark, part 15 FCC*2, RSS-210*2
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation System Description Copyright © Symeo GmbH 2009 Page 9 of 33 *1 Depending on distance and application parameters *2 Only valid for FCC labeled stations 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 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: 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 station has an explicit identification Number in one system. A system consists of 2 stations. The first station has the station number 1 (SID 1), the second station has the station number 2 (SID 2). 2.4.2 Group-ID (GID) A pair of LPR-1DXi stations 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.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation System Description Copyright © Symeo GmbH 2009 Page 10 of 33 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). 2.5 Versions of LPR-1DXi stations For the LPR-1DXi stations several different versions are available: Overview: Options ID Switching threshold / distance reading Distance output resolution Basic device BSB000719 0 to 120 m 0,5m increments Option 1 BSB000754 0 to 500 m 0,5m increments Option 2 BSB000755 0 to 120 m Resolution up to ±5 cm Option 3 BSB000756 0 to 500 m Resolution up to ±5 cm Basic device *1 BSB000900 0 to 120 m 0,5m increments Option 1 *1 BSB000901 0 to 500 m 0,5m increments Option 2 *1 BSB000902 0 to 120 m Resolution up to ±5 cm Option 3 *1 BSB000903 0 to 500 m Resolution up to ±5 cm *1 in compliance with part 15 off FCC rules and with RSS-210 of Industry Canada Please take care that the distances for the switching points in your application are within the maximum possible distance range of your version of LPR-1DXi. The distance for positive signal control, monitoring the functionality of two stations, is possible up to 1800m.

SYMEO Local Positioning Radar System LPR-1DXi Product Documentation Protocol Description Copyright © Symeo GmbH 2009 Page 28 of 33 6 Protocol Description 6.1 General Description This protocol describes the interface between a LPR-1DXi station 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-B 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 30 shows the general structure of the data packet. TYPE DATASTART0x7e1 byte 1 byte 1 byteCRC2 byteEND0x7f Figure 30: 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.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation Protocol Description Copyright © Symeo GmbH 2009 Page 29 of 33 6.1.3 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-B system the byte stuffing must be reserved to get the original symbol. Then the CRC is updated with the original symbol. 6.2 Data Types 6.2.1 Type 0x00 – Distance Data Direction: LPR-1DXi → User Content Length Value Data type START 1 0x7E TYPE 1 0x00 Source* (LPR address 6.3.1) 2 0x#### see chapter 6.3.1 Destination* (LPR address 6.3.1) 2 0x#### see chapter 6.3.1 Antenna number 1 0x11 unsigned integer Distance [mm] 4 0x#### #### signed integer Velocity [mm/s] 4 0x#### #### signed integer Level [dB] 1 0x## signed integer Error 6.3.3 1 0x## unsigned integer Status 6.3.2 1 0x0# unsigned integer CRC 2 0x#### END 1 0x7F Total length without byte stuffing: 21 byte *) Measurements are always executed by a LPR-1DXi base station (station 1), this means, the base station measures its distance towards a transponder unit (station 2). The source field always contains the address of the LPR-1DXi base station (station 1). The destination field contains the address of the measured transponder (station 2). 6.2.2 Example of Distance Data 7E 00 08 03 08 02 11 00 00 10 62 00 00 00 7A E6 00 00 AF C4 7F Figure 31 - Protocol for a measurement of distance data This protocol shows a simple example for 1D measurement.
