1 Introduction 1.1 Purpose This document is provided to OEMs for the installation of the ETERNA2 into a finished product. Provided the OEM’s usage of ETERNA2 is compliant with the requirements included in Section 6, the OEM is not required to complete radio certification of ETERNA2’s radio performance in FCC, IC and CE regulated geographies. In addition this manual provides the information necessary to perform certification of the ETERNA2 module for other geographies. 1.

3. Receive the packet: up to 128 bytes of data maximum + 5 bytes preamble/SFD 4. Turnaround: radio waits 1 ms and then is set to transmit 5. Transmit: radio sends an ACK (21 bytes of data + 5 bytes preamble/SFD), then turns off Total transmit time for an ACK is plus all overhead (SFD / Preamble / Ramp) is 1.101 ms. Measured records and calculations of ETERNA2 radio transmit duty cycling are included in “ETERNA Duty cycle.pdf”.

2.2 API UART ETERNA2 offers a comprehensive Application Programming Interface, API, that provides full programmatic access to control the device, monitor its status (such as battery charge and network status), and provide access to the wireless mesh network. Messages over the API UART are HDLC encoded and require specific software to support command and response communication required for regulatory testing. Refer to the SmartMesh API Guide for details.

4.5 Radiated Emissions Radiated emission tests, such as described in EN 301 489-17, are designed to test that a DUTs unintentionally radiated emissions are below defined limits. As the radio itself has been modularly certified this is not a test of the emissions with the radio in operation. To prevent ETERNA2 from actively running it’s radio during connect to ETERNA2’s CLI port and enter the set command as follows: > radiotest on Reset or power cycle ETERNA2.

For best results power up all devices within a couple of minutes. Mote 1 is always the mote in the Network Manager and the assignment of motes 2 through 3 are based upon order of joining the network which is not deterministic.

Connect a splitter or RF-T to the DUT radio, attaching a spectrum analyzer or power meter to one port and the nonDUT radio via 70 dB of attenuation to the other port. Power up both the manager and the mote. Connect to the CLI port of the manager. Enter the following command > onechan Where channel number is any channel between 0 and 14.

FCC Testing ETERNA2 complies with Part 15.247 modular (Intentional Radiator) of the FCC rules and regulations. In order to fulfill FCC certification requirements, products incorporating ETERNA2 must comply with the following: 5. An external label must be provided on the outside of the final product enclosure specifying the FCC identifier as described in 6.3.2 below. 6. The antenna must have lower gain than specified in 6.3.1. 7.
