Chapter 1: Important Safety and Compliance Information This section provides important information for your safety and product compliance. USA FCC PART 15 SPECTRUM COMPLIANCE This device complies with Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. Operation is subject to the following two conditions: • This device may not cause harmful interference.
Validity of using the module certification: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product.
Please see the approved antennas in Chapter 5: Approved Antennas for the Modular LE. RF Exposure (FCC/ISED) This equipment complies with radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 21 cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Before installation, discharge electrostatic buildup by touching a metal pipe or other earth-grounded metal object prior to touching the meter body, register housing, or Itron device. DO NOT DROP Warning: While Itron modules are designed to withstand a drop, dropping the module may damage the device and void the warranty LABELING The following requirements apply to any products that use this module.
Chapter 2: Overview This document provides information on the design, construction, and operation of the Itron Riva Modular LE device (module). The module is a fully shielded communications device which can be integrated into a host device where it provides communications capability for joining the Itron OpenWay Riva network. The module is used with an external antenna. The module housing is a lead free, non-vented, surface mount shield that provides protection for the internal components.

Chapter 3: Module Description The Itron Riva Modular LE (module) is a single full modular low energy radio communications device. The module is designed for integration into 3rd party host devices wanting to communicate by radio frequency (RF) on an Itron Riva network. As shown in Figure 2, the module is contained inside the silver rectangular perimeter and is fully shielded (shield is removed in this image).

Chapter 4: Connecting, Initializing and Programming the Module CONNECTING THE MODULE TO A HOST BOARD OR HOST DEVICE The Itron Riva Modular LE is designed with castellations (pads) which are mapped to specific functions. The mapping begins in the lower leftmost corner of the module and moves counter clockwise around the module with pads numbered from 1 to 54. Figure 5: Module pad numbering When the module is paired with a host, the following mapping will facilitate integration.

4. Connect the serial to USB cable with the three pin connector on the far left of the image shown in Figure 8. The yellow in the middle and the black (ground) in the position closest to the end of the board. Plug the USB end of the cable you’re your laptop. Figure 8: Module on host board and connected to Serial to USB cable Once all the connections are in place, your board should be connected as shown in Figure 9 and you are ready to load firmware on your module.
Chapter 5: Approved Antennas for the Modular LE The Modular LE can be operated with an external antenna. The required antenna impedance is 50Ω. The host device will determine what type of antenna connector is available. The module was tested with the Itron host board which contains an external uFL antenna connector as shown in Figure 10. Figure 10: uFL antenna connector on Itron host board An antenna or antenna extension cable can be attached to the uFL connector as shown here.
Two antennas were tested and approved during the FCC testing and certification process. The Modular LE has been designed and approved per FCC and ISED rules to operate with the two antennas which are described here. LAIRD MODEL 0600-00048 The Laird model 0600-00048 omni directional antenna with 2.0 dBi gain was successfully tested for transmission in the 902-928 mHz frequency band.
