The L-ZM2102 is dedicated for wireless control and monitoring of residential products like lighting and appliance control, energy management, access control, security and building automation. Together with the patented Z-Wave Protocol the L-ZM2102 Z-Wave Module delivers a complete highly reliable RF communication solution. The Z-Wave Protocol uses Frame Acknowledgement, Retransmission, Collision Avoidance, Frame Checksum Check and sophisticated Routing to assure reliable full home coverage. The L-ZM2102 Z-Wave Module contains the integrated ZW0201 Z-Wave Single Chip, system crystal and RF front-end circuitry. The ZW0201 Single Chip is an integrated chip containing RF Transceiver, 8051 MCU core, SRAM, Flash Memory for Z-Wave Protocol and OEM Application software storage, Triac Controller and a wide range of HW interfaces. This complete RF solution makes it very easy for OEM customers to RF enable their products without having to do the time consuming work of designing, verifying and optimizing the RF design and thereby enables faster time to marked.

Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. If the FCC ID for the module is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains FCC ID: TOB-LZM2102 LOGITECH CONFIDENTIAL (Printed on 10/3/2005 ) page 7 of 19 MPQ Test Radio Z 2005-10-03 1 PRODUCT DESCRIPTION 1.1 Overview The L-ZM2102 Z-Wave Module is a fully integrated module containing all the HW and SW required to ZWave enable OEM products. The L-ZM2102 Z-Wave Module contains the Z-Wave ZW0201 Single Chip, System Crystal, RF Front-end and RF Supply Voltage Filtering. Only the antenna needs to be implemented by the developer designing the Z-Wave enabled product. Figure 1 ZM2102 Z-Wave Module Block Diagram The L-ZM2102 Z-Wave Module contains a system crystal, why no external crystal is needed. In order to get a high reliable and high performance RF communication, the RF Front-end has an optimized and throughout tested matching circuitry, a narrow band SAW filter dedicated for Z-Wave communication and there are filtering of the RF circuitry supply voltage. The L-ZM2102 Z-Wave Module is connector- LOGITECH CONFIDENTIAL (Printed on 10/3/2005 ) page 8 of 19 MPQ Test Radio Z 2005-10-03 less using Castellation Notches for easy mounting of the module to an OEM Application PCB. The L-ZM2102 Z-Wave Module has a top shield that improves noise immunity of the module and enables the module to be mounted by a standard pick-and-place machine on the production line. The Z-Wave Protocol is designed to enable automatic network address assignment at installation, and simple inclusion/exclusion of nodes. These protocol-handling techniques ensure easy installation, expansion, and management of the Z-Wave control network. Furthermore each Z-Wave network has its own unique Network Identifier preventing control problems or interference from neighboring networks. The Z-Wave Protocol has a well-defined Application-Programming-Interface (API) enabling easy and fast Application SW development. 1.2 Signal Description Notch Signal Name GND RESET_N P1.7 / INT1 P1.6 / PWM / INT0 P1.5 GND P1.2 / MISO P1.4 / SCK P1.3 / MOSI 10 P1.1 / ADC3 / RXD 11 VCC 12 GND 13 P0.1 / LOGITECH CONFIDENTIAL (Printed on 10/3/2005 ) page 9 of 19 MPQ Test Radio Z 2005-10-03 ADC1 / TRIAC Name Notch # 14 P0.0 / ADC0 / ZEROX 15 P1.0 / ADC2 / TXD 16 GND 17 GND 18 RF in/out Figure 2 L-ZM2102 Outline and Signals I/O Description 10, 13, 14, 15 1, 6, 12, 16, 17 Power INT[1:0] 3, 4 I/O Interrupt: The signal can be either level or edge trigged.

Please note that the SPI interface (MISO, MOSI and SCK) is not available for the Application SW in some Z-Wave protocol API’s, see [3]. Table 1 L-ZM2102 Signal Description All signals in Table 1 except RF, VCC and GND are connected directly to the corresponding signals on the ZW0201 Z-Wave Single Chip on the L-ZM2102 Z-Wave Module. A detailed description of these signals is given in the ZW0201 Z-Wave Single Chip datasheet [1]. 1.3 RF Front-End 1.3.1 RF input/output The L-ZM2102 Z-Wave Module is equipped with a SAW filter that rejects the unwanted frequencies both in receive and transmit operations. Figure 3 L-ZM2102 RF Front-end Circuitry The RF input/output on the ZW0201 is a single ended input/output that is internally matched to 50 ohm. 1.3.2 Antenna Matching The L-ZM2102 Z-Wave Module is using an antenna placed on the Application Module, the matching of the external antenna to 50 ohm (SAW filter impedance) must be made on the Application Module. As the L-ZM2102 Z-Wave Module is integrated into various products, different types of antennas can be implemented to get the best RF performance, i.e. range and reliability. In [4], a good overview of the different antennas is given as well as their pro’s and con’s. In the case the antenna is not 50ohm a matching network must be implemented between the L-ZM2102 Z-Wave Module and the antenna. The matching network can for example be a “pi” or a “T” structure as shown in Figure 4.

Two decoupling capacitors should be placed at the VCC pin (EP11) a 4.7uF and a 100nF capacitor is recommended. The two capacitors should be placed as close EP11 as possible and the capacitor should be placed between the LZM2102 Z-Wave Module and the via that goes to the power plane as shown in Figure 7. Figure 7 Placement of decoupling capacitor (power pin, EP11) 2.9.2 Ground Plane In order to minimize any noise coupling from noisy signals (typically power products) it is recommended LOGITECH CONFIDENTIAL (Printed on 10/3/2005 ) page 17 of 19 MPQ Test Radio Z 2005-10-03 to insert as much ground cobber below the L-ZM2102 Z-Wave Module as possible on the Application PCB. 2.9.3 Antenna Interconnection As the RF signal (EP18) is 50ohm the trace from the EP18 to the matching circuitry (see 1.3.2) must be 50ohm. The Application PCB designer must therefore take the PCB layer structure and thickness into account when designing the 50ohm trace (either Microstrip or Stripline). 3 SOFTWARE 3.1 SPI Interface The signals ‘P1.2/MISO’, ‘P1.4/SCK’ and ‘P1.3/MOSI’ signals are in some SW API’s used by the protocol to store Routing Tables and HomeID in an external EEPROM. When these SW API’s are used, the Application SW must not use these three signals. Table 9 shows the available SW API’s and in which the SPI interface is used by the protocol. SW API SPI interface used by Protocol Slave No Routing Slave No Enhanced Slave Yes Controller Yes Static Controller Yes Installer Yes Bridge Yes Table 9 SW API / SPI availability 3.2 EEPROM Some SW API’s require an external EEPROM to be implemented on the Application PCB for protocol information storage (like routing table, HomeID etc.). The SPI interface is used to access the EEPROM and the ‘P1.5’ signal (EP5) is used by the Z-Wave Protocol as EEPROM Chip Select. To assure proper control of the EEPROM chip select signal during reset and power-up a pull up resistor on the P1.5 should be implemented as shown in Figure 8. LOGITECH CONFIDENTIAL (Printed on 10/3/2005 ) page 18 of 19 MPQ Test Radio Z 2005-10-03 Figure 8 External EEPROM Only a part of the EEPROM is used for protocol data storage, the Application SW can use the remaining memory area using an API call (see [3]). For the EEPROM memory area requirements of the protocol API please refer to the documentation for the Z-Wave Controller code selected (see [3]).
