Operational Description
ETERNA2 provides an 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
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.

Command and Response
2.1
CLI UART
ETERNA2 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
ETERNA2. T he UART is configured at 9600 baud, 8-bit, no parity, 1 stop bit, and does not support flow control.
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.

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 t he 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.

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>.
4.1.1
Channel Map
Radiotest commands use the <chanMask> parameter to define which channel or channels the radio will operate on when a
command is issued. The parameter <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. For example, 0x7fff results in operation
on channels 0 through 14 and 0x0001 results in operations only on channel 0. Table 1 provides a mapping for single channel
operation for each channel and the corresponding channel number as defined in this document.

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> <stationId>
ETERNA2 Regulatory User Guide

Where <chanMask> would nominally be set to 0x0001 (low) , 0x0080 (mid) or 0x4000 (high) and <time> in seconds.
The <stationId> parameter was added in the version 1.4.0 release of the SmarMesh IP Mote, version 1.3.0 of the
SmartMesh IP Manager and version 1.1.2 of the SmartMesh WirelessHART mote. Earlier versions of software should omit
the <stationId> parameter. The <stationId> parameter should be set to 0, zero, for all certification radio testing.
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 (+8dBm),
the highest output power setting used in the OEM product.
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 its
normal state:
> radiotest off
Reset or power cycle ETERNA2.
10
Dust Networks
ETERNA2 Regulatory User Guide
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 its 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 subsequently 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 its
normal state:
> radiotest off
Reset or power cycle ETERNA2.
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 wit h the
radio in operation. To prevent ETERNA2 from actively running the 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 its
normal state:
> radiotest off
Reset or power cycle ETERNA2.
ETERNA2 Regulatory User Guide

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 du e 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: 00-1 7-0D -00-00-1 9-20 -2C, ver: 2.2.1.7

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 m ote 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:
12
Dust Networks
ETERNA2 Regulatory User Guide
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 comman d
being sent. A simple method, uses the windows program TeraTerm Pro. TeraTerm Pro can be downloaded at
http://sourceforge.jp/proj ects/ttssh2/releas es/. Configure TeraTerm as follows to communicate with the network managers
CLI port with the following steps:
1.
Launch TeraTerm
2.
Select the serial port corresponding to the CLI interface to the network manager
ETERNA2 Regulatory User Guide
Dust Networks

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

sendln
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.

Duty Cycle, Tx-Sequence, Tx-Gap and Medium Utilization
The follow command sequences provide a method for demonstrating the maximum duty cycle ETERNA2 could generate in a
SmartMesh IP or SmartMesh WirelessHART network:
> radiotest on
Start test:
> radiotest tx <testType> <chanMask> <power> <sysId> [<repeatCnt> {<pkLen>
<delay>...}]
<testType> is Type of transmission test to initiate: ‘pkcca’ = packets with clear channel assessment, '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. 0x7FFF
results in operation on channels 0 through 14 and 0x0001 results in operations only on channel 0. <power> sets the radio
output power, a value of 8 should be used for maximum power. <sysId> is the network ID used for packet transmission this
parameter allows for testing of multiple devices in the same RF space and is intended for manufacturing support, not radio
certification testing. The <sysId> field for certification testing can be left at zero, 0. 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 s. 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 an IP system on the low channel using every slot issue the
following command:
> radiotest tx pkcca 0x0001 8 0 0 125 10035 24 5700 24 5700 24 5700
This will demonstrate a sequence of one transmission of a maximum length packet followed by three acknowledge packets.
To have the radio operate in a hopping sequence that enables hopping on all 15 channels issue the following command:
> radiotest tx pkcca 0x7FFF 8 0 0 125 10035 24 5700 24 5700 24 5700
To demonstrate the maximum duty cycle of a WirelessHart system on the highest channel when every sl ot is active, issue the
following command:
> radiotest tx pkcca 0x4000 8 0 0 125 14733 24 8700 24 8700 24 5822
To have the radio operate in a hopping sequence that enables hopping on all 15 channels issue the following command:
> radiotest tx pkcca 0x7FFF 8 0 0 125 14733 24 8700 24 8700 24 5822
After completing tests that require the DUT to hop outside of a network, use the radiotest off command to return the device
to its normal state:
> radiotest off
Reset or power cycle ETERNA2.
