4 Dust Networks ETERNA2 Regulatory User Guide 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. 1.2 Scope This document is intended for those who are responsible for installing and testing the ETERNA2 module design for regulatory requirements. 1.3 References [1] IEEE Std 802.15.4-2006, Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for Low-Rate Wireless Personal Area Networks (LR-WPANs) 1.4 Definitions DUT Device Under Test Mote A node in a mesh network Low Channel The lowest frequency channel occupied by ETERNA2 is channel 0 centered at 2405 MHz. This channel corresponds to channel 11, as defined by [1]. Mid Channel The channel closest to the center of the 2.4 GHz ISM band occupied by ETERNA2 is channel 7, centered at 2440 MHz. This channel corresponds to channel 18, as defined by [1]. High Channel The highest frequency channel occupied by ETERNA2 is channel 14, centered at 2475 MHz. This channel corresponds to channel 25, as defined by [1]. 1.5 General Description ETERNA2 combines a microprocessor and a IEEE-802.15.4 radio with networking capabilities to provide a time synchronized, ultra low power network, designed to enable operation from battery sources for extended periods of time. The design is a PCB including “castellated” leads for access to the device and network, an SoC (includes radio and CPU), power supply filtering, and an MMCX connector to the antenna port or integral antenna. 1.6 Operational Description ETERNA2 provides a IEEE 802.15.4 compliant radios that modulate a DSSS OQPSK set of symbols at a chip rate of 2 Mcps. Dust radios operate on a TDMA time schedule that uses either 7.25 or 10 ms timeslots. A transmit timeslot consists of 5 stages: 1. Initialization: radio is prepared for transmit (transmitter is off) 2. Ramp: transmitter is ramped to peak power 3. Transmit: 128 bytes of data maximum + 5 bytes preamble/SFD 4. Turnaround: radio is set to receive 5. Receive: radio waits in receive for ACK, then turns off Total transmit time for a 128 byte packet plus all overhead (SFD / Preamble / Ramp) is 4.33ms. A receive timeslot consists of 5 stages: 1. Initialization: radio is prepared for receive 2. Check for start of packet – if no packet is received within a guard time the radio is disabled and no further action is taken
ETERNA2 Regulatory User Guide Dust Networks 5 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”. When the radio is not in operation, the CPU is occasionally (every few seconds for a few milliseconds) operating, monitoring temperature and voltage. The remainder of the time the ETERNA2 in a low power mode operating solely from a 32 kHz crystal source. 1.7 Block Diagram Cortex-M3TimersSched.AutoMACAESFlash512 KBFlash Controller802.15.4Framing DMA802.15.4Mod802.15.4DemodAPIUART (6-pin)IPCS SPI Slave PTATPMU / Clock ControlBat.

The interface operates at LVTTL levels matching the VSUPPLY input to ETERNA2. The UART is configured at 9600 baud, 8-bit, no parity, 1 stop bit, and does not support flow control.
6 Dust Networks ETERNA2 Regulatory User Guide 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. 3 Test Configurations Test configurations can be divided into two distinct configurations, one for Radiated immunity and a second for Emissions and Conducted Measurements. 3.1 Radiated Immunity Operation of the network in the presence of an interferer can most easily be monitored by operating ETERNA2 as a mote participating in a network. In this configuration, the RF link between the ETERNA2 and a network manager can be exercised and simultaneously monitored via the network managers UART CLI port. Communication and monitoring to the UART CLI port can be done via generally available terminal emulation software, such as TeraTerm, HyperTerminal, or iTerm2. 3.2 Emissions and Conducted Measurements Emissions and Conducted measurements can be made with ETERNA2 integrated into a product or stand alone. When integrated into a product a convenient method to invoke commands over ETERNA2’s CLI or API UART should be considered as part of the product design. To access the CLI port and power on ETERNA2 in a stand alone configuration, a Samtec MTMM-111-04-S-S-175-003, connector should be installed on J2, as shown below, J2 per the pinout shown below, provides both power and connection to ETERNA2’s CLI port. Connection to pins 1 through 6 are optional for CLI access.
ETERNA2 Regulatory User Guide Dust Networks 7 4 Tests 4.1 Conventions Input from the user during a test will be in bold. Command line information will be shown in Plain Text. Command parameters, either numerical, alphanumeric or enumerated, are shown between greater than and less than symbols. I.e. <parameter>. . 4.2 Receiver Emission Tests Much of the testing focused on the receiver can be accomplished by enabling ETERNA2’s radio to receive for an extended period of time using the following sequence: Power up ETERNA2 and connect to the CLI port. Enter the following command > radiotest on Reset or power cycle ETERNA2 and enter the following command > radiotest rx <chanMask> <time> Where <chanMask> would nominally be set to 0x0001 (low) , 0x0080 (mid) or 0x4000 (high) and <time> in seconds.. This sequence enables testing of: • Receiver Conducted Spurious Emissions Operating (EN 300 328) • Receiver Radiated Spurious Emissions Operating (EN 300 328, FCC 15.109) • AC Conducted Emissions (FCC 15.207) After completing tests that require radiotest commands (tx and rx) use the radiotest off command to return the device to it’s normal state: > radiotest off Reset or power cycle ETERNA2. 4.3 Transmitter Power and Spectral Tests Much of the testing focused on the transmitter can be accomplished by enabling ETERNA2’s radio to continuously transmit a modulated signal using the following sequence: Power up ETERNA2 and connect to the CLI port. Enter the following command: > radiotest on Reset or power cycle ETERNA2 and enter the following command: > radiotest tx cm <chanMask> <power> Where <chanMask> would nominally be set to 0x0001 (low) , 0x0080 (mid) or 0x4000 (high) and <power> to 8, the highest output power setting used in the OEM product.
8 Dust Networks ETERNA2 Regulatory User Guide This sequence enables testing of: • Effective Isotropic Radiated Power (EN 300 328) • Maximum Spectral Power Density (EN 300 328, FCC 15.247(e)) • Frequency Range / Band Edge (EN 300 328 / FCC 15.247(d)) • Transmitter Conducted Spurious Emissions Operating (EN 300 328, FCC 15.247(d)) • Transmitter Radiated Spurious Emissions Operating (EN 300 328, FCC 15.247(d)) • AC Conducted Emissions (FCC 15.207) • Bandwidth (FCC 15.247(a)(2), RSS 210 99% Bandwidth) • RF Power Output (FCC 15.247(b)(3)) After completing tests that require radiotest commands (tx and rx) use the radiotest off command to return the device to it’s normal state: > radiotest off Reset or power cycle ETERNA2. NOTE: If testing encompasses measuring ETERNA2’s output power or PSD, Power Spectral Density, over a range of voltages, the radiotest off command must be issued every time the voltage to ETERNA2 is changed to ensure accurate output power measurements. During product operation ETERNA2, dynamically adjusts its regulation to it’s power amplifier, based upon the supply voltage to keep the supply to the PA constant. The radiotest tx cm and radiotest tx cw commands do not dynamically adjust the power to the PA, only taking a single measurement when the command is issued. WARNING: It is possible to permanently damage ETERNA2, by initiating a radiotest tx cm or radiotest tx cw command at a low voltage and susiquently raising the voltage without issuing a radiotest off command. 4.4 Transmitter Carrier Tests Testing ETERNA2’s carrier frequency accuracy can be done by enabling ETERNA2’s radio to continuously transmit an unmodulated signal using the following sequence: Power up ETERNA2 and connect to the CLI port. Enter the following command > radiotest on Reset or power cycle ETERNA2 and enter the following command > radiotest tx cw <chanMask> <power> Where <chanMask> would nominally be set to 0x0001 (low) , 0x0080 (mid) or 0x4000 (high) and <power> to 8, the highest output power setting used in the OEM product. After completing tests that require radiotest commands (tx and rx) use the radiotest off command to return the device to it’s normal state: > radiotest off Reset or power cycle ETERNA2.
ETERNA2 Regulatory User Guide Dust Networks 9 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. The radio is now inactive and will remain inactive until a tx or rx command is given. After completing tests that require radiotest commands (tx and rx) use the radiotest off command to return the device to it’s normal state: > radiotest off Reset or power cycle ETERNA2. 4.6 Radiated Immunity Radiated immunity tests, such as described in EN-61000-4-3, are designed to test a DUTs operation due to an out of band interferer. When performing such tests the test system should be verified to prove the test system is not injecting noise due to harmonic distortion into the 2.4 to 2.4835 GHz band. To perform this class of test ETERNA2 should be placed in a network and the network function can be demonstrated as follows: Create a network of devices with a network manager and two ETERNA2 motes (the minimum configuration to form a network). Make sure the MAC addresses for both ETERNA2 motes and the manager are clearly labeled on each device. Connect to the manager’s CLI port and issue the following commands: > login user > show mote * Mote #1, mac: 00-17-0D-00-00-19-20-2C, ver: 2.2.1.7 State: Oper, Hops: 0.0, Uptime: 2561, Age: 0 Number of neighbors (parents): 2 (0) Number of links (tx/rx): 17 (0/4) Number of no bitmap links : 13 Neighbors: <- #2 Q: 28 <- #3 Q: 28 Mote #2, mac: 00-17-0D-00-00-19-33-07, ver: 2.2.1.7 State: Oper, Hops: 1.0, Uptime: 2475, Age: 13 Number of neighbors (parents): 2 (1) Number of links (tx/rx): 15 (2/2) Neighbors: -> #1 Q: 28 <- #3 Q: 29 Mote #3, mac: 00-17-0D-00-00-10-20-4D, ver: 2.2.1.7 State: Oper, Hops: 1.4, Uptime: 2460, Age: 7 Number of neighbors (parents): 2 (2)
10 Dust Networks ETERNA2 Regulatory User Guide Number of links (tx/rx): 14 (2/0) Neighbors: -> #1 Q: 28 -> #2 Q: 29 Note: It can take up to 10 minutes for the network to form and will take longer if the manager has been powered up for a lengthy period of time. 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. To determine which mote number is which device use the MAC address as a reference: To force a message to a particular mote enter: ping <mote number> which will look like: > ping 2 > Sending ping request to mote 2 > Ping response from mote 2, time=900 msec v=3645 t=25 Ping commands that fail will return with a timeout error message: Ping from mote 2 timed out Inherently the manager CLI port will generate a notification when a device fails to communicate and falls off the network. During normal network operation devices are communicating at least every 15 seconds. To reduce dwell time the use of a script to ping the target device will increase the radio traffic. The traffic rate will be twice the rate of the ping command being sent. A simple method, uses the windows program TeraTerm Pro. TeraTerm Pro can be downloaded at http://sourceforge.jp/projects/ttssh2/releases/. Configure TeraTerm as follows to communicate with the network managers CLI port with the following steps: 1. Launch TeraTerm
ETERNA2 Regulatory User Guide Dust Networks 11 2. Select the serial port corresponding to the CLI interface to the network manager 3. Setup the Serial Port via the Setup -> Serial port … Menu item: 4. Create a TeraTerm macro, a text file with the extension *.ttl, with the following content: ; Tera Term macro for pinging Dust motes in a network over the managers CLI port ; ; File: ping_loop.ttl ; Description: Looping ping macro for support of Radiated Immunity testing of Dust ; Networks Radios. Set for one ping two messages every delayInMiliSeconds period, ; with 255 steps from 80 to 1000 MHz. For Radiated Immunity above 1 GHz testing is ; only intended to be performed for bands where portable radios are permitted to ; operate - this range and therefore the test duration will change over time. timeout = 10 steps = 255 delayInMiliSeconds = 3000 sendln for i 1 steps sendln
12 Dust Networks ETERNA2 Regulatory User Guide sendln "ping 2" mpause delayInMiliSeconds next pause 5 sendln "#----- Macro Finish -----" end 5. Call the macro from the TeraTerm menu Control -> Macro and load the created macro file. This will create a series of Ping request and responses from the mote. 4.7 Minimum Frequency Occupation, Hopping Sequence and Tests Testing ETERNA2’s Minimum Frequency Occupation, Hopping Sequence is most easily measured by operating ETERNA2 in a self hoping mode. Power up both the manager and the mote and connect to the CLI port of each. Enter the following command > radiotest on Reset or power cycle both the mote and manager. The devices will hop between channels and transmit despite not being joined in a network. Start test: > radiotest tx <testType> <chanMask> <power> [<repeatCnt> {<pkLen> <delay>...}] <testType> is Type of transmission test to initiate: 'pk' = packets, 'cm' = continuous modulation, 'cw' - continuous wave. <chanMask> is a hex bitmap of channels to use with the LSB corresponding to channel 0 and the MSB corresponding to channel 15. Channel 15 in product is never used. E.g. 7fff results in operation on channels 0-14 and 0001 results in operations only on channel 0. <power> sets the radio output power, a value of 8 should be used for maximum power. The transmitter will transmit in a sequence of packets and gaps defined by a series of alternating <pkLen> and <delay> parameters. The <pkLen> parameter defines the packet length in terms of bytes and is limited to a range of 2 to 125 bytes. Note the protocol will append 8 bytes to the packet payload, so the actual transmitted length of bytes <pkLen> + 8, for a maximum of 133 bytes. The <delay> parameter defines the delay from the start of one packet to the next in μs. The <repeatCnt> parameter defines the number of times that the defined packet sequence will repeat. A <repeat> value of 0 results in the sequence repeating indefinitely. To demonstrate the maximum duty cycle of the system on the low channel using every slot issue the following command: > radiotest tx pk 0x0001 8 0 125 11483 24 6855 24 6833 24 2177 To demonstrate the maximum duty cycle of the system on the middle channel when every other slot is active, issue the following command: > radiotest tx pk 0x0080 8 0 125 11483 24 6855 24 6833 24 2177 To demonstrate the maximum duty cycle of the system on the high channel when every other slot is active, issue the following command: > radiotest tx pk 0x4000 8 0 125 11483 24 6855 24 6833 24 2177 After completing tests that require the DUT to hop outside of a network, use the radiotest off command to return the device to it’s normal state: > radiotest off Reset or power cycle ETERNA2. 4.8 Occupied Channel Bandwidth, Duty Cycle and Dwell Time Tests Testing ETERNA2’s Occupied Channel Bandwidth, Duty Cycle and Dwell Time, as per EN 300 328, is most easily measured by operating ETERNA2 in a network, in which both the network manager and the mote are configured to hop on a
ETERNA2 Regulatory User Guide Dust Networks 13 single channel. If possible perform the test in a conducted fashion, connecting 70 dB of attenuation to the radio that is not the DUT. Connect a splitter or RF-T to the DUT radio, attaching a spectrum analyzer or power meter to one port and the non-DUT 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 <channel> Where channel number is any channel between 0 and 14. Reset or power cycle both the mote and manager. The devices will hop on a single channel after rebooting and forming a network. After completing tests that require the DUT to hop on a single channel, use the onechan off command to return the manager to its normal state: > onechan off Reset or power cycle ETERNA2. 4.9 Radio Inactive Emission Tests To test ETERNA2 for emissions with the radio inactive: Power up ETERNA2 and connect to the CLI port. Enter the following commands: > set mode slave > reset NOTE: The device will remain inactive through power cycling. To resume radio testing, enter the following commands: > set mode master > reset 5 Specifications Table 1 Normal Operating Conditions Parameter Min Typ Max Units Comments Operational supply voltage range (between VDD and VSS) 2.1 3.76 V Including noise and load regulation Operating temperatures -40 +85 °C 5.1 Radio Specifications ETERNA2 operates as an IEEE-802.15.4 compliant radio, both transmitting and receiving in a TDMA channel access method.

Pour réduire le risque d’interférence aux autres utilisateurs, l’antenne doivent être choisies telle que la puissance isotrope rayonnée équivalente (PIRE) ne dépasse pas ce qui est nécessaire pour une communication réussie. 6.4.1 RF Exposure / Exposition aux Rayonnements Radiofréquences The radiated output power of ETERNA2 is far below the IC radio frequency exposure limits. ETERNA2 complies with IC radiation exposure limits set forth for an uncontrolled environment. When nearby persons has to be kept to ensure RF exposure compliance, in order to comply with RF exposure limits established in the ANSI C95.1 standards, the distance between the antennas and the user should not be less than 20 cm (8 inches). ETERNA2 shall not be co-located with any other tranmsitter within 20 cm; otherwise further transmitter testing may be required. La puissance émise par ETERNA2 est largement inferieure aux limites d’exposition aux rayonnements de la norme IC. ETERNA2 est conforme aux limites d’exposition aux rayonnements de la norme IC établies pour un environnement non contrôlé. Pour garantir la conformité aux limites d’exposition aux rayonnements de la norme ANSI C95.1, la distance entre l’antenne et toute personne doit être supérieure à 20 cm (8 pouces). ETERNA2 ne doit pas être localisé à proximité d’un autre transmetteur à moins de 20 cm ; le cas échéant, d’autres mesures de rayonnement pourraient être nécessaires.
