500M Module and Daughter Card Data Sheet 500M Module 1.8.1. External Antenna Integration (RSS-GEN) This radio transmitter has been approved by Innovation, Science and Economic Development (ISED) Canada to operate with the antenna type with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types that are not described are strictly prohibited for use with this device because they have a gain greater than the maximum gain indicated for that type.
500M Module and Daughter Card Data Sheet 500M Daughter Card 2. 500M Daughter Card The 500M module is available in a Daughter Card form factor with power regulator and MMCX antenna connector. The Daughter Card offers full modular certification in select jurisdictions to enable developer partners to reduce time-to-market. Customers also have the option of potting the Daughter Card for use in harsh environments. 2.1.
500M Module and Daughter Card Data Sheet 500M Daughter Card The Daughter Card includes a DC/DC buck converter which regulates the input voltage to the 500M 3V for power amplifier and 2.55 V to RF. The UART can be accessed through the USB cable or HDK shield board headers. If a user does not want to connect their Daughter Card to the HDK, then the host application processor can connect to the 500M module through a UART serial interface using CoAP over HDLC.

500M Module and Daughter Card Data Sheet Reliability and Regulatory Certification 3. Reliability and Regulatory Certification The 500M and all components are designed for 20-year continuous operation.
500M Module and Daughter Card Data Sheet Reliability and Regulatory Certification 2. This device must accept any interference received, including interference that may cause undesired operation. Co-location of this module with other transmitters that operate simultaneously are required to be evaluated using the FCC multi-transmitter procedures of KDB 447498 and 996369 for RF exposure, and KDB 996369 D04 for EMC.
500M Module and Daughter Card Data Sheet Reliability and Regulatory Certification Le périphérique hôte doit être correctement étiqueté pour identifier le module dans le périphérique hôte.
500M Module and Daughter Card Data Sheet Reliability and Regulatory Certification 3.1.6. OEM Certifications Itron 500M is FCC/IC Certified as Limited Modular Approval (LMA). LMA may be granted to a device which cannot meet all the requirements of a Single Modular Transmitter and if compliance can be demonstrated under the operating conditions in which the device will be used.
500M Module and Daughter Card Data Sheet Reliability and Regulatory Certification Option 3: If all rules from Option 2 are used, but a different type of antenna is required for the application, request a Change in ID application to reuse data from the current FCC/IC Grant, then apply for a Class 2 Permissive Change to add the antenna. The integration would require some additional conformity against CFR 47 Parts 15.203, 15.209, and RF exposure to add antenna to the Certification.
500M Module and Daughter Card Data Sheet Terms and Conditions 4. Terms and Conditions 4.1. Important Notice Radio Frequency (RF) transmission and reception cannot be guaranteed. Data transmission using Itron’s wireless modules is susceptible to delays or data loss even when used as recommended with a well-designed network.
