SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 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.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 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.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 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.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 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.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation *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.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 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 LPR1DXi system needs different frequency channels.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 3 Hardware All corresponding installation, repair and servicing work must be carried out by qualified and trained technicians. 3.1 Component setup of the LPR-1DXi station The LPR-1DXi station consists of mounting bracket A, casing with electronic devices B and antenna C as shown in Figure 3.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation The antenna C has to be mounted in correct polarization (C2) as shown in Figure 3 3.2 Cable glands, interfaces and LED display of the LPR-1DXi station The casing B has two cable glands for power cable (B6) and cable for the connection to the on-board relays (B5). Additionally the pressure equalization membran (B7) is shown.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation On the side of the casing the USB port (B4) for parameter setting with the software SymeoWizard and two two-colored LED (B8, B9) are located, displaying different statuses of the device. Figure 5 3.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 4 Installation 4.1 Important Instructions for Installation Avoid entry of foreign objects or liquids into the system unit, especially on the PCB stack in casing B. The seal (B10) seals front and rear element when it is mounted correctly. Otherwise the housing will not be sealed in a water-proof manner.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 4.3 RS 232 Connection For optional distance reading RS 232 is connected using the RS232 terminal block B3. Figure 8 shows the pin assignment. Please use the same cable as for the power supply with additional three wires. Figure 8: RS232 terminal block B3 4.4 Relay Connection Relays are connected using the relay terminal block B1. Figure 9 shows the pin assignment for the seven switch relays with dry contacts.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 4.5 Mounting 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 Figure 10: LPR-1DXi station rear view The LPR-1DXi station is delivered pre-mounted (casing B and antenna C), and with a separate mounting bracket A.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation Mount the mounting bracket A on a pole or wall at a suitable place. Do not tighten the screws of the adjustment yet, the system must be aligned first. Mount the LPR-1DXi casing on the mounting bracket A with 4 hex nuts A4 using flat wrench SW8. Carefully align both units (refer to chapter 4.6). When the system is powered, the red LED B9 of the display element is turned on.
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 4.6.2 Alignment of LPR-1DXi stations The LPR-1DXi stations 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 stations have to be tilted (compare picture 3 vs. picture 4 in Figure 12).
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 5 Commissioning 5.1 Requirements In order for a station to be successfully commissioned, the LPR-1DXi stations must have been installed correctly: The station has been installed.

SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 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).
SYMEO Local Positioning Radar System LPR-1DXi Product Documentation 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.
