Product Specification and User Manual RFID GEN3 System 1 General information This document contains the functional and electrical specifications for the RFID DESS System GEN3. The product is available in two variants of communication interface: a CAN or a MOWP. The MOWP based device replaces previous generation of the RFID Post. Mechanical details are found on the product drawings listed in Table 2. Software and communication details are found in the software specification (1001392597).
Product Specification and User Manual RFID GEN3 System 2 RFID GEN3 System Overview The RFID System is composed of 2 parts, the RFID Key and the RFID Post. Details about these are provided in section 0and 0 respectively.
Product Specification and User Manual RFID GEN3 System Figure 2: RFID DESS System Block Diagram The vehicle ECU powers the RFID Post from the positive switched battery connection (KL15). Once powered, the RFID Post senses the RFID Key’s magnet using its internal hall sensor. The hall sensor’s output is pulled low if a magnetic field is sensed, allowing the vehicle engine to start.
Product Specification and User Manual RFID GEN3 System 2.1 RFID Key As illustrated in Figure 3, the RFID Key is composed of a plastic housing, 2 trim caps (not shown), a magnet, a RFID tag and a spacer. The last 3 elements are contained in an intermediate shell (not shown), needed to seal them from the external environment. The tag is ISO15693 compliant.
Product Specification and User Manual RFID GEN3 System 2.2 RFID DESS Post As illustrated in Figure 4 and Figure 5, the Post is composed of a plastic cover, an O-ring, a main PCB, a header, a secondary PCB and a plastic housing. The plastic cover, plastic housing and O-ring protect the internals from the external environment. The cover provides a mechanical mating interface for a connector. The CAN variant has a 5-pin connector, the MOWP variant has a 4-pin connector.
Product Specification and User Manual RFID GEN3 System 3 RFID GEN3 Functional Specification 3.1 Bidirectional Communication 3.1.1 CAN variant The RFID Post is designed to exchange information via CAN protocol with the ECU. Refer to software specification. 3.1.2 MOWP variant The RFID Post is designed to exchange information via Maxim 1-Wire protocol with the ECU. It is also possible to communicate with the module using a MPI2.5 CAN-to-MOWP converter for diagnostics purposes. 3.
Product Specification and User Manual RFID GEN3 System Figure 6: Cut-off System 3.3 Operating and Storage Temperature The RFID DESS System has an operating and storage temperature range of -40°C to +85°C. 3.4 RFID Tag Reading Sequence Figure 7 shows the sequence performed by the RFID Post’s microcontroller to acquire the UID from power up. This sequence takes less than 500ms to be completed. The communication between the tag and the RFID is compliant with the wireless protocol ISO15693.

Product Specification and User Manual RFID GEN3 System 4 RFID GEN3 Electrical Specification 4.1 Connector The electrical connection between the RFID Post shall use the sealed connector Delphi GT 150 series. Refer to product drawing for more details. Figure 8: CAN Variant Connector Figure 9: MOWP Variant Connector The following table outlines the RFID Post’s pinout.
Product Specification and User Manual RFID GEN3 System 4.1.1 Pin A: GND This pin is used as the RFID Post power return, to be connected to the vehicle’s main ground. Characteristic Unit Minimum Nominal Maximum Voltage, absolute maximum rating (steady state) V -18 --- 18 Table 5: GND Characteristics. 4.1.2 Pin B: CONTACT This pin is used as an engine cut-off signal, pulled low to activate engine.
Product Specification and User Manual RFID GEN3 System 4.1.4 Pin C: 1-WIRE / MOWP This pin is used for communication with an ECU or a diagnostic tool. Characteristic Unit Minimum Nominal Maximum Voltage, absolute maximum rating (steady state) V -18 --- 18 Voltage, operating V Logic level V 5 Low: 1.45 --- High: 3.25 Table 8: 1-WIRE / MOWP Characteristics. 4.1.
Product Specification and User Manual RFID GEN3 System 5 RF Specifications The RFID Post has the following RF performance over temperature. Characteristic Unit Minimum Nominal Maximum RF Output Power W 0 --- 0.4 Operating Frequency MHz 13.55 13.56 13.57 Frequency Stability ppm -90 - +90 Table 11: RF Characteristics The antenna is built-in the PCB and cannot be replaced without modifying the PCB. No external antenna can be connected to this device.
Product Specification and User Manual RFID GEN3 System 7 Localization and Installation on Vehicle The RFID GEN3 System shall be installed as the previous DESS System generation. The RFID Post should be secured to the vehicle’s body using the Post retaining ring 278 002 963. The Post’s sphere and thread must protrude out of the vehicle’s body and be accessible by the operator, while the Post’s main body shall be inside the vehicle’s body. Figure 10: Example of Vehicle Installation 7.1 Metallic Materials.
Product Specification and User Manual RFID GEN3 System 7.2 Noise Sources Identifications The RFID Post shall be located away from vehicle radiated sources. A minimum of 15 cm in any direction between a radiated noise source and the RFID GEN3 System is recommended. This intended position shall be validated in any new vehicle or configuration change, using the diagnostic tool described in section 8.
Product Specification and User Manual RFID GEN3 System 8 Diagnostic Tool KA has designed a tool to analyze performance using the RFID Post. This tool allows the monitoring of performance of the RF transmission between the RFID Key and Post in real time. This tool can be used to diagnose conducted noise, radiated noise or transmission perturbations due to proximity of metallic materials.
Product Specification and User Manual RFID GEN3 System 8.2 MOWP Variant Figure 11: RFID Diagnostic Tool The diagnostic tool reads the RFID tag every 30 ms. In case of reading error, the probe wire will be pulled low during a period of 30 ms. The probe wire can be monitored using an oscilloscope having a minimum bandwidth of 100 MHz.
Product Specification and User Manual RFID GEN3 System Figure 12: Example of probe wire output At power up, the RFID diagnostic tool will send the RFID tag’s UID over the 1-wire interface. This last approximately five (5) seconds. During this period, the switch allows a temporary connection of the 1-Wire output to the vehicle’s ECU for it to authenticate the RFID Key. This allows testing while the vehicle is normal operation.
Product Specification and User Manual RFID GEN3 System 8.2.1 Radiated Noise Validation The main purpose of this validation is to determine whether the RFID GEN3 System is in the presence of a radiated noise source that could potentially affect the transmission of the RF transmission between the RFID Key and Post. The vehicle under test shall be started in regular operation. The RF Diagnostic tool should be connected as shown in the Figure 13. Figure 13: Configuration for Radiated Noise Validation.
Product Specification and User Manual RFID GEN3 System 8.2.2 Metallic Presence Validation The main purpose of this validation is to determine whether the RFID GEN3 System is in the presence of a metallic material that could affect the RF transmission between the RFID Key and Post. The vehicle engine and other electrical devices must be completely off. The RF Diagnostic tool should be connected as shown in the Figure 13.
Product Specification and User Manual RFID GEN3 System Once the system is powered-up and the vehicle is started, the diagnostic tool can be used to monitor whether conducted noise could be affecting the performance of the RFID signal.
Product Specification and User Manual RFID GEN3 System 9 Validation plan The product meets the requirements laid out in the Technical Requirement Document as detailed in the test plan 111550 - DVP&R PV1.xslx.
