1 Introduction
1.1 Purpose
This document is provided to OEMs for the installation of the ETERNA1 into a finished product. Provided the OEM’s usage
of ETERNA1 is compliant with the requirements included in Section 6, the OEM is not required to complete radio
certification of ETERNA1’s radio performance in FCC, IC and CE regulated geographies. In addition this manual provides
the information necessary to perform certification of the ETERNA1 module for other geographies.
1.2 Scope
This document is intended for those who are responsible for installing and testing the ETERNA1 module design for
regulatory requirements.

1.4 Definitions
DUT Device Under Test
Mote A node in a mesh network
Low Channel The lowest frequency channel occupied by ETERNA1 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 ETERNA1 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 ETERNA1 is channel 14, centered at 2475 MHz.
This channel corresponds to channel 25, as defined by [1].
1.5 General Description
ETERNA1 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
ETERNA1 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
ETERNA1 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 ETERNA1 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 ETERNA1 in a low power mode operating solely from a 32 kHz
crystal source.

2 Command and Response
2.1 CLI UART
ETERNA1 includes a Command Line Interface, CLI, UART that supports a full set of text commands described in this
document to enable product certification. The interface operates at LVTTL levels matching the VSUPPLY input to
ETERNA1. The UART is configured at 9600 baud, 8-bit, no parity, 1 stop bit, and does not support flow control.
6 Dust Networks ETERNA1 Regulatory User Guide
2.2 API UART
ETERNA1 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 ETERNA1 as a mote
participating in a network. In this configuration, the RF link between the ETERNA1 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 ETERNA1 integrated into a product or stand alone. When
integrated into a product a convenient method to invoke commands over ETERNA1’s CLI or API UART should be
considered as part of the product design. To access the CLI port and power on ETERNA1 in a stand alone configuration, a 2
mm header should be installed on J4, as shown below,
J1 and J4 per the pinout shown below, provides both power and connection to ETERNA1’s CLI port. Connection to pins
J1’s pins 3 through 11 are optional for CLI access.

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 ETERNA1’s radio to receive for an extended
period of time using the following sequence:
Power up ETERNA1 and connect to the CLI port. Enter the following command
> radiotest on
Reset or power cycle ETERNA1 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 ETERNA1.
4.3 Transmitter Power and Spectral Tests
Much of the testing focused on the transmitter can be accomplished by enabling ETERNA1’s radio to continuously transmit a
modulated signal using the following sequence:
Power up ETERNA1 and connect to the CLI port. Enter the following command:
> radiotest on
Reset or power cycle ETERNA1 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 ETERNA1 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 ETERNA1.
NOTE: If testing encompasses measuring ETERNA1’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 ETERNA1 is changed to ensure accurate
output power measurements. During product operation ETERNA1, 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 ETERNA1, by initiating a radiotest tx cm or radiotest tx
cw command at a low voltage and subsiquently raising the voltage without issuing a radiotest off command.
4.4 Transmitter Carrier Tests
Testing ETERNA1’s carrier frequency accuracy can be done by enabling ETERNA1’s radio to continuously transmit an
unmodulated signal using the following sequence:
Power up ETERNA1 and connect to the CLI port. Enter the following command
> radiotest on
Reset or power cycle ETERNA1 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 ETERNA1.
ETERNA1 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 ETERNA1 from actively running it’s radio during connect to ETERNA1’s CLI port and enter
the set command as follows:
> radiotest on
Reset or power cycle ETERNA1. 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 ETERNA1.
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 ETERNA1 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 ETERNA1 motes (the minimum configuration to form a
network). Make sure the MAC addresses for both ETERNA1 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

10 Dust Networks ETERNA1 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
ETERNA1 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 ETERNA1 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 ETERNA1’s Minimum Frequency Occupation, Hopping Sequence is most easily measured by operating ETERNA1
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 ETERNA1.
4.8 Occupied Channel Bandwidth, Duty Cycle and Dwell Time Tests
Testing ETERNA1’s Occupied Channel Bandwidth, Duty Cycle and Dwell Time, as per EN 300 328, is most easily
measured by operating ETERNA1 in a network, in which both the network manager and the mote are configured to hop on a
ETERNA1 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 ETERNA1.
4.9 Radio Inactive Emission Tests
To test ETERNA1 for emissions with the radio inactive:
Power up ETERNA1 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
