3 System Description 3.1 System Overview A KY-LOC 1D.02.01 system consists of two units that conduct a range measurement between each other. The two units are using the time of flight of the Radar signals to measure a precise distance between each other. The units can be configured to receive the distance values on one unit or on both units. The units must be configured as Relay and Remote devices, as explained in chapter 6. By default, the Relay device does provide access to the information relevant to the distance measurement, while the remote device is only used for measuring purposes. However, is an option to have the same information on the Remote device if it is configured accordingly, as described on chapter 6. Both units need to be powered with either DC power supply or PoE (802.11af). The unit, where the range measurement is requested, needs to be connected via a data interface, either Ethernet or RS-485. Figure 1 shows the complete system including mounting bracket for mounting on any suitable structure. If other interfaces are necessary, e.g. ProfiNET, ProfiBus, Ethernet/IP, ModBus, can be provided via the KY-XTRA B interface devices. For FCC and CA, the system is for fixed operation only. This includes installation in fixed equipment, even if the sensor itself moves within the equipment. 3.2 System Technical Data For the technical data please refer to the Datasheet of the device (refer to RD-1). The latest datasheet can be downloaded from the KYMATI webpage (www.kymati.com) 3.3 Range Measurement & Range Computation To perform a range measurement between two devices, they need to be synchronised. Therefore, the Relay device sends out a synchronization signal and the Remote synchronizes onto that signal. When the devices are synchronized, they start automatically with the range measurement and stay synchronized. Additionally, the front LEDs are used to show whether the devices are synchronizing or synchronized, for more information please refer to chapter 4. If the devices lose their wireless connection to each other (e.g. object in between) for a long time, they will automatically re-synchronize.

To power the device, there are three options:

1.) An external DC power supply via the connector X1 can be used 2.) A PoE (802.11af) can be provided via X2 3.) or both interfaces can be used to power the device to have a redundant power supply. For data communication there are two interfaces. A RS-485 interface on connector X1 and an Ethernet interface on connector X2 (see Figure 11). Only one data interface should be used at a time. All possible communication, if configured properly, and power options are supported by the sensor. If other interfaces/protocols like Profinet, Profibus, Ethernet/IP, ModBus, digital I/Os or similar are needed, an accessory from the KY-XTRA B family is necessary (for more details please visit www.kymati.com).

6 Setting Up the Devices and System Operation This chapter describes how to operate the KY-LOC 1D.02.01 sensor. The following steps must be taken to have a basic measurement running:

1. Install the devices (see chapter 6.1) 2. Power up the devices (see chapter 6.2) 3. Configure the communication links (see Communication Setup message in Chapter 7) 4. Configure one device as Relay device (see chapter 7) 5. Connect to the device and run the system (see chapter 6.5) 6. Do the first measurement run (see chapter 6.6) After this procedure, the system may be installed and will start automatically measuring if both sensors are powered and synchronized. 6.1 Installation of the KY-LOC 1D.02.01 Sensor For a proper operation, the following parts must be considered:

The devices must face each other. For long range operation they should be aligned Minimum of 2 m distance between the two units must be maintained to guarantee the better than 5 . specified accuracy. The orientation of the devices must be the same (please refer to chapter 3.2). The vertical and horizontal offset must be smaller than 0.5 m.

Figure 16: Typical Set-up In default mode, only the relay can send out the distance information via its own interfaces. After mounting the device, the cable must be connected. On the Remote side only power is needed, at the side of the Relay, power and communication is necessary (chapter 5.1). If the Remote does not have a communication, the device must be configured in advance via a communication cable. Do not use unintended force to mount the connectors. If the connector does not fit, check the coding/index notch of the connector. Open connector sockets need to be protected with a cap. Only with sealed connectors, the device has its stated IP rating 6.2 Powering Up First connect all cables to the devices and then power up them. After the installation of the devices the power can be turned on. Therefore, a proper power supply as described in chapter 4.4 must be used. After power up, the power LED shall illuminate constantly, stating that the device is properly powered. In case of wrong polarity, the device has a polarity protection, hence if the power LED is not illuminating, the power must be removed immediately.

6.3 Initial Configuration The devices must be configured during initial setup and the parameters must be configured through the communication interface. To configure the device the Ethernet or the RS-485 interface can be used. How to connect to the device is described above. It is only possible to configure the devices via the RS-485 or the Ethernet Interface. So, both devices must be connected to configure them. This can be done before installation. Each device should first be configured with a valid Ethernet configuration with a reachable destination target (for example the controlling host) or a valid RS-485 Bus Identifier. See the Communication Setup Message in Chapter 7. Please note that this approach can also be used to recover a device in case of misconfiguration through the use of a Product ID and the Serial Number (S/N) which both can be found on the Product label on the side of the device. Once the communication setup has been done, it is recommended to download the configuration and store it. This configuration can be used in case of a replacement of the device to bring settings fast to a new device or to copy the configuration to another system. All configurable parameters are described in Chapter 7. 6.4 Connect to the System After the sensors are powered, the KY-LOC 1D.02.01 will start automatically. The Relay will start sending out a signal and the Remote tries to synchronize to that signal. This can take up to 120 seconds. If the devices are synchronized, they start measuring the distance. The distance can be read out via one of the interfaces described in chapter 7. 6.5 Running the System The KY-LOC 1D.02.01 is working correct when the status LED is illuminating constantly. The device is equipped with a power LED. This LED is the indicator that power is available at the device. Normally the LED glows continuously. When the information LEDs are illuminating constantly then valid range information is available. 6.6 First Run Before using the system, a reference measurement should be recorded. Therefore, the system should be running from the minimal distance to the maximum possible distance and the range and SNR values should be recorded during the movement. Afterwards the Zero Point should be set. Therefore, the device carrying the moving sensor should drive to the position were the zero of the measurement should be. At this position, the zero command should be executed. 6.7 Turning off the System To turn the KY-LOC 1D.02.01 off, switch off the power supply. The status LED and power LED will turn off. After unintended power cycle, the system will be automatically restart. This document is the property of KYMATI GmbH and must not be copied or disclosed without its written authorisation.

7 Interface Description There are two possibilities to communicate with the device, either through RS-485 or Ethernet. RS-485 (TIA / EIA-485-A) The RS-485 is a unidirectional 2 wire interface, with cable lengths up to 100m. The wires should have a termination Resistor of 120 at both ends. RS-485 Parameters Transmission Rate Start Bit Stop Bit Parity Bits Data Bits Flow Control RS-485 Values 921.6 KBaud 1 (logical low) 1 (logical high) None 8 None Table 4: RS-485 SW Interface Configuration To communicate with KYMATI Radars through a RS-485 connection, messages need to be encoded or decoded using byte stuffing into/from a protocol frame as shown in the Figure below. Figure 1:

Protocol Description The byte 0x7E is used to detect the beginning and 0x7F is used to detect the end of valid protocol frame. In this setting we use the byte stuffing technique based on the following transition table:

Original Byte Stuffed Byte Sequence 0x7E 0x7D 0x7F Table 5: Transition table 0x7D 0x5E == 0x7D (0x7E XOR 0x20) 0x7D 0x5D == 0x7D (0x7D XOR 0x20) 0x7D 0x5F == 0x7D (0x7F XOR 0x20) During encoding, we search for the original bytes listed in the transition table inside a given message and replace it with the stuffed byte sequence. The encoding can be implemented This document is the property of KYMATI GmbH and must not be copied or disclosed without its written authorisation.

through a bitwise XOR operation between the original byte and the modifier byte 0x20. During the decoding step one must search for the byte 0x7D, remove it and apply the modifier byte through a bitwise XOR operation to the following byte. All other bytes not listed in the transition table are not altered. The maximum size of such a single protocol frame is 258 bytes, if one has to translate every single byte in our message. Ethernet (TIA-568A/B) The Ethernet is a standard 100 BASE-T Ethernet according to IEEE 802.3 Clause 24. The wiring is according to TIA-568A/B. When communicating with the KYMATI Radars through an Ethernet connection, the messages are directly encapsulated into UDP packets without any need for byte stuffing. During bootup, the device will automatically send UDP packets to 192.168.75.1 on port 27513. All data types and data structure fields use the little-endian byte ordering (also known as Intel byte order). A KYMATI Radar message has a maximum size of 128 bytes and consists of three parts: A header field, a CRC field and a dynamic field which depends on the actual content being transmitted. The header part with a size of 8 bytes is described in the following table:

Field Version ContentType Offset Datatype 0 Unsigned Integer (16 Bit) Unsigned Integer (16 Bit) Source Bus Identifier Unsigned Integer (8 Bit) Destination Bus Identifier 5 Unsigned Integer (8 Bit) Source Routing Identifier Unsigned Integer (8 Bit) Destination Routing Identifier Unsigned Integer (8 Bit) 2 4 6 7 Description Version of the Protocol Current Version: 2 Specifies the type of the content specific data field: see Chapter 4 for possible values. Field which contains the identifier of the source device on the bus. Host/Controller Device is always 0 Field which contains the identifier of the destination device on the bus. Host/Controller Device has always 0.

The CRC part with a size of 2 Bytes is described in the following table:

Name CRC Offset 0 Datatype Unsigned Integer (16 Bit) The CRC is computed on Header and the Content specific data field. The CRC field is always at the end of a KYMATI Radar message. Description CRCCCITT with generator 0x1021 and seed 0xFFFF The Content specific data field is determined by the ContentType Field of the header part and can have a maximum size of 118 bytes. When sending messages from a Host over Ethernet or RS-485 use the HOST (0) value for the Source Bus Identifier. The Destination Bus Identifier field is ignored when communicating through Ethernet. For RS-485 connections, however, this field is either the actual bus identifier on the bus, or the special value 0xFF, which can be used to broadcast a message to all devices simultaneously. Please note that there will be no response messages for broadcasts to avoid message collisions on the RS-485 bus. The following values for the source and destination routing identifiers are supported:

Routing Identifier Name Microcontroller RS-485 Ethernet Value 0 1 2 When sending messages from a host over Ethernet to the device use the Ethernet value for the Source Routing Identifier field. Similarly, when sending messages from a Host over RS-

485 use the RS-485 value. If this is not set correctly, the responses will be sent back through the wrong connection. When receiving messages from the device the corresponding source and destination fields will be flipped. In the case of an Ethernet connection, there is also an option to use a fixed size message format for a more convenient use with PLCs. In that case, the content specific data field is padded with additional zero bytes such that the messages are always 128 bytes in size, including the header and CRC field. The CRC computation then also includes the additional padding bytes. For some commands, a series of messages needs to be exchanged between the host and the device in a specific order. If the device does not get an expected message in a certain amount of time, it will automatically abort the current command and will wait for a new command. 7.1 Device Commands The KYMATI Secondary Radar protocol currently supports the following content types:

8 Operational Limitations 8.1 Fresnel Zone Clearance To prevent performance degradation, the Fresnel zone clearance (at least of 1st order) between two sensors should be respected. The following notation is used hereafter:

Sensor #1 Sensor #2 GSU Antenna d: distance between antennas F1: radius of 1st Fresnel Zone Figure 17: First Fresnel Zone The Fresnel Zone is the grey area shown in Figure 17. It is mainly depending on the system frequency and the distance between the two sensors. The maximum radius of the first Fresnel zone can be computed with the following formula, where it has already been predefined that KY-LOC 1D.02.01 operates at f = 61 GHz:

F1, max (max. radius of the Fresnel Zone) is in units of meters, as well as the antenna distance d. Distance [m]

50 100 300 500 Max Radius of Frenzel Zone [m]

0.80 1.14 1.97 2.54 Table 6: Maximum radius of Fresnel zone at different distances. This also implies that the two sensors have to be mounted in such a way that there is still some spacing to neighbouring objects, in order to respect the Fresnel zone clearance. Objects obstructing the Fresnel Zone can cause signal degradation depending on the amount of the obstruction. E.g. it shall be avoided to place any objects in the field of view of the sensor or mount the sensor in locations close to obstacles, which might affect the overall range performance and/or the measurement quality. 8.2 Line of Sight Clearance The most important technical aspect for the system is to have a continuous Line of Sight condition between the remote device and the relay device at any time. A proper Line of Sight analysis during the first time shall be made taking also possible temporary objects into account.

If objects are in the line of sight it may be that the device measures a wrong distance or even loose the contact and therefore also the synchronization totally. In the case of a total loss, the synchronisation like the one at start-up will take place when the object is no longer in the line of sight, which might affect the overall range performance and/or the measurement quality. 8.3 Simultaneous Operation Adjacent KY-LOC 1D.02.01 systems must use of different channel configurations avoiding interference between the different systems. It is in the responsibility of the system operator to ensure that either adjacent KY-LOC 1D.02.01 systems make use of different channel configurations or, when re-using the same channel configuration for different KY-LOC 1D.02.01 systems, an adequate spatial separation is kept between different KY-LOC 1D.02.01 systems. Currently the system supports up to 6 channels and in the future, this might increase based on the customer needs (software upgrade).
