4 General description 4.1 Sensor description The main task of the UMRR is the detection of any reflectors in the field of view, to measure the distance, the relative speed and the angle to the shortest reflector (and to other reflectors), to detect motion and to track (filter) the results over time.
4.3 General Performance Data After power up or reset, the sensor readings are within specified performance within <10 seconds. In Table 4-1 the general performance data of UMRR-11 Type 132 are given.

6 Cables and connectors 6.1 Sensor connector The sensor connector is a 12-pin male (plug) circular bayonet type connector (water proof IP67, series LF10WBRB-12PD, manufacturer Hirose, Japan). A female counterpart (socket), e.g. LF10WBP-12S, has to be used to connect to the sensor. The pin numbering of the socket is shown in Figure 6-1 and the pin description is given in Table 6-1.
7 Data interfaces 7.1 CAN data interface This specification gives a detailed description of the CAN data communication used in the UMRR based systems on the sensor CAN. The UMRR is compliant with CAN 2.0B standard. CAN is a very robust full duplex bidirectional interface. 7.
Figure 7-1: CAN bit timing for UMRR sensor Figure 7-2: CAN bit timing as defined by the CAN protocol 7.3 RS-485 data interface The RS-485 interface from the UMRR sensor has a predefined speed of 115200 baud/s. Typical other data rates are between 921.6kBit/s and 56.7kBit/s. The RS-485 message payload is identical to the CAN format. The data messages will be sent in several packets of one byte. Every cycle begins with a start sequence and ends with a calculated checksum and an end sequence.
Table 7-1: RS-485 message structure Byte\Bit 0 1 2 3 x x x x x x x x 0 1 2 3 4 7 6 5 4 3 2 1 Start sequence (4 x UINT8) 0 0xCA 0xCB 0xCC 0xCD Data payload (n x UINT8) XOR Checksum (UINT8) 0xEA 0xEB 0xEC 0xED End sequence (4 x UINT8) Every data message consists of its own message ID, the number of used data bytes and the data bytes itself. The checksum is calculated on all data except the start sequence and the end sequence. The Checksum is a simple XOR Assignment of all n data bytes.
7.4 Transceiver schematics In Figure 7-3 and Figure 7-4 the exact DSP board schematic of the UMRR is given. The CAN pins of the Co-Processor are connected to a CAN transceiver, which is connected to the pins CAN1_P and CAN1_N. Similarly, the RS485 pins of the Co-Processor are connected to a RS485 transceiver, which is connected to the pins RS485_TX_ETHRN_TX4_P, RS485_TX_ETHRN_TX4_N, RS485_TX_CAN2_ETHRN_TX3_P, RS485_TX_CAN2_ETHRN_TX3_N.
8 Applications It can be used for long and medium range collision warning (CW), adaptive cruise control (ACC) applications in autonomous driving systems. One or multiple sensors are specifically integrated into vehicle models of automotive OEMs. Usually there is a certain OEM-specific engineering effort required for the adaptation to specific vehicle models and the test and qualification procedures to be applied.
9 Declaration of Conformity 9.1 Declaration of Conformity for USA This device has been tested and found to comply with the requirements set forth in 47 CFR Part 95, Subpart M for both fundamental emissions and unwanted emissions. These limits are designed to provide reasonable protection against any harmful interference when the device is operated in a commercial environment. Modifying the device without smartmicro’s authorization may result in the device being no longer compliant with FCC requirements.
9.2.2 Déclaration de conformité en francais Le present appareil est conforme aux CNR d’Industrie Canada applicables aus appareils radio exempts de licence. Léxploitation est autorisée aux deux conditions suivantes: (1) l’appareil ne doit pas produire de brouillage, et (2) l’utilisaeur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.
