MPQ Test Radio Z 2005-10-03 Compliance Statement FCC Class B Part 15 This device complies with part 15 of the FCC Rules. 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.
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.
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.

MPQ Test Radio Z 2005-10-03 Figure 6 Recommended Reflow Temperature Profile 2.9 Application PCB Layout Recommendation 2.9.1 Supply Voltage As the L-ZM2102 Z-Wave Module contains a RF transceiver good supply voltage decoupling is important. Two decoupling capacitors should be placed at the VCC pin (EP11) a 4.7uF and a 100nF capacitor is recommended.
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.
