1 Introduction
This document describes the Telegesis ETRX351 and ETRX357 ZigBee
®
modules which have
been designed to be easily integrated into another device and to provide a fast, simple and low
cost wireless mesh networking interface.
The Telegesis ETRX3 series modules are based on the Ember ZigBee
®
platform consisting of the
single chip EM351 or EM357 combined with the ZigBee
®
PRO compliant EmberZNet meshing
stack. Integration into a wide range of applications is made easy using a simple AT style
command interface and advanced hardware design.
The configurable functionality of the Telegesis AT Commandset often allows the ETRX3 series
ZigBee
®
modules to be used without an additional host microcontroller saving even more
integration time and costs. In addition to the Telegesis AT Commandset, the ETRX351 and
ETRX357 modules can be used with custom-built firmware whilst representing an ideal platform for
custom firmware development in conjunction with the Ember development kits.
No RF experience or expertise is required to add this powerful wireless networking capability to
your products. The ETRX351 and ETRX357 offer fast integration opportunities and the shortest
possible time to market for your product.
1.1 Hardware Description
The main building blocks of the ETRX351 and ETRX357 are the single chip EM351 and EM357
SoCs from Ember, a 24MHz reference crystal and RF front-end circuitry optimized for best RF
performance. The modules are available with on-board antenna or alternatively a U.FL coaxial
connector for attaching external antennae. Modules with the U.FL connector are identified by the
“HR” suffix.
The integrated antenna is an Antenova Rufa, and details of the radiation pattern etc are available
from the Antenova website [5].

The ETRX351 and ETRX357 are used for ZigBee
®
(www.zigbee.org) applications. If you wish to
create your own custom firmware, and not use the pre-loaded Telegesis AT-Command interface,
you will need the Ember InSight toolchain, consisting of InSight Desktop™ together with a
comprehensive integrated development environment (IDE). The Ember development environment
is currently not suitable for developing an IEEE802.15.4-only application that does not use the
ZigBee
®
layer.

2.4 ICASA Approvals
The ETRX351, ETRX357, ETRX351HR and ETRX357HR have been certified to be used in South
Africa.
2.5 Australia and New Zealand (C-Tick)
The ETRX351, ETRX357, ETRX351HR and ETRX357HR have been certified to be used in
Australia and new Zealand.
2.6 Declarations of Conformity
Telegesis (UK) Ltd has issued Declarations of Conformity for all ETRX3 series ZigBee® RF
Modules, which cover Radio Emissions, EMC and Safety. These documents are available from our
website or on request.
2.7 IEEE 802.15.4
IEEE 802.15.4 is a standard for low data-rate, wireless networks (raw bit-rate within a radio packet
of 250kbps @2.4GHz) which focuses on low cost, low duty cycle, long primary battery life
applications as well as mains-powered applications. It is the basis for the open ZigBee
®
Protocol.
2.8 The ZigBee® Protocol
The ZigBee
®
Protocol is a set of standards for wireless connectivity for use between any devices
over short to medium distances. The specification was originally ratified in December 2004, paving
the way for companies to start making low-power networks a reality.
ZigBee
®
uses the IEEE 802.15.4 radio specification running on the 2.4GHz band, plus three
additional layers for networking, security and applications. What makes the specification unique is
its use of a mesh network architecture which, in bucket chain style, passes data from one node to
the next until it lands at its destination. The network is self-healing and adapts its routing as link
quality changes or nodes move. Furthermore, nodes can be defined as End Devices which do not
act as routers, but can therefore be put into a low-power sleep state.
The enhanced version of the ZigBee
®
standard (or ZigBee
®
2006) was released in December
2006, adding new features and improvements to the only global wireless communication standard
enabling the development of easily deployable low-cost, low-power, monitoring and control
products for homes, commercial buildings and industrial plant monitoring. In 2007 the ZigBee
Alliance introduced the PRO featureset which offers advantages over earlier versions, including
• Truly self healing mesh networking
• Messages can now travel up to 30 hops
• Source-Routing for improved point to multipoint message transmission
• Improved security including Trust-Centre link keys
• New message types and options
The Telegesis AT Commandset, which by default ships on all ETRX3 series products is based on
the ZigBee
®
PRO featureset. For more information on the Telegesis AT Commandset please refer
to the separate documentation at www.telegesis.com.

EM35x radio circuit is in transmit mode. PC5 is not usable on the long range version of the
ETRX35x as this GPIO is used internally as TX_ACTIVE to control the external RF frontend.
{2} The serial UART connections TXD, RXD, CTS and RTS are PB1, PB2, PB3 and PB4 respectively
{3} When using the Telegesis AT Commandset, RTS/CTS handshaking is selectable in firmware. See
the AT Command Manual.
{4} If PA5 is driven low at power-up or reset the module will boot up in the bootloader

Figure 2: Hardware Diagram
The ETRX351, ETRX351HR, ETRX357 and ETRX357HR are based on the Ember EM351 and
EM357 respectively. The EM351 and EM357 are fully integrated 2.4GHz ZigBee transceivers with
a 32-bit ARM
®
Cortex M3
TM
microprocessor, flash and RAM memory, and peripherals.
The industry standard serial wire and JTAG programming and debugging interfaces together with
the standard ARM system debug components help to streamline any custom software
development.
In addition to this a number of MAC functions are also implemented in hardware to help
maintaining the strict timing requirements imposed by the ZigBee and IEEE802.15.4 standards.
The new advanced power management features allow faster wakeup from sleep and new power
down modes allowing this 3
rd
generation module to offer a longer battery life than any 2
nd
generation modules on the market.
The EM35x has fully integrated voltage regulators for both required 1.8V and 1.25V supply
voltages. The voltages are monitored (brown-out detection) and the built in power-on-reset circuit
eliminates the need for any external monitoring circuitry. An optional 32.768 kHz watch crystal can
be connected externally to pads 3 and 4 in case more accurate timing is required. To utilize the
external watch crystal custom firmware is required.
4.1 Hardware Interface
All GPIO pins of the EM351 or EM357 are accessible on the module’s pads. Whether signals are
used as general purpose I/Os, or assigned to a peripheral function like ADC is set by the firmware.
When using the Telegesis AT Commandset please refer to the AT Commandset manual and the
development kit manual for this information and when developing custom firmware please refer to
the EM35x datasheet [2].

5 Firmware Description
The modules will be pre-loaded with a standalone bootloader which supports over-the-air
bootloading as well as serial bootloading of new firmware.
In order to enter the standalone bootloader using a hardware trigger pull PA5 to ground and
power-cycle or reset the module. To avoid entering the standalone bootloader unintentionally
make sure not to pull this pin down during boot-up unless the resistance to ground is >10kΩ. (A
pull-up is not required).
In addition to the standalone bootloader the modules also contain the current release of the
Telegesis AT-style command interface as described in the Telegesis AT command dictionary and
the Telegesis user guide. Check www.telegesis.com for updates. Each module comes with a
unique 64-bit 802.15.4 identifier which is stored in non-volatile memory. The commands and
responses pass through the serial port of the ETRX35x as ASCII text, so a simple terminal
application will usually suffice. We provide Telegesis Terminal for interaction with the module but it
is not an essential feature.
The pre-loaded AT-style command interface firmware is based on the latest EmberZNet meshing
stack which implements routers/coordinators as well as (sleepy) end devices. [End devices have
no routing responsibility and therefore are allowed to go to sleep, whilst still being able to send and
receive messages via a parent router. In addition to classical sleepy and non-sleepy end devices
the module firmware also supports mobile (sleepy) end devices capable of changing their parent
quickly whenever they change their position within the network.]
A router is typically a mains powered device whilst a sleepy end device (SED) can be battery
powered.
The module is also able to act as a coordinator and Trust Centre through external host control.
The AT style command line supplies all the tools required to set up and manage a ZigBee network
by allowing easy access to the low-level functionality of the stack.
The Telegesis firmware uses the meshing and self healing EmberZNet PRO stack to overcome
many of the limitations of the tree network topology of the ZigBee® 2006 stack by using the ZigBee
PRO featureset.
The Telegesis firmware allows low-level access to physical parameters such as channel and
power level. Parameters that define the functionality of the ETRX35x module and also allow
standalone functionality are saved in non-volatile memory organised in so-called S-Registers. The
SPI and I2C buses are not supported by the current firmware release, but can be used with custom
firmware.
5.1 Custom Firmware
For high volume customers the firmware can be customised on request. In addition to this the
ETRX3 series of modules is an ideal platform for developing custom firmware. In order to develop
custom firmware the Ember Insight toolchain is required.

5.2 Software Interface
Using the default firmware the ETRX35x is controlled using a simple AT-style command interface
and (mostly) non-volatile S-Registers. In order to get a full listing of all the available AT-
Commands, please refer to the AT command dictionary document which corresponds to the
firmware revision you intend to use.
In addition to the command dictionary there are user guides explaining the features of the firmware
in more detail. If you need to find out which firmware resides on your module simply type “ATI”
followed by a carriage return and you will be prompted with the module’s manufacturing
information.
The Development Kit manual describes how to upgrade the firmware either via a serial link or over
the air.

10.1 TX Power Characteristics
The diagrams below show the typical output power and module current in dependency on module
EM35x power setting . Power settings above 3dBm have Boost Mode enabled. Please note that
the output power is independent of the supply voltage as the radio is supplied by an internally
regulated
voltage.

Table 14: ETRX3 Physical Dimensions
For ideal RF performance when using the on-board antenna, the antenna should be located at the
corner of the carrier PCB. There should be no components, tracks or copper planes in the keep-
out area which should be as large as possible. When using the U.FL RF connector the keep-out
area does not have to be obeyed. Note: The modules’ transmit/receive range will depend on the
antenna used and also the housing of the finished product.

14 Recommended Footprint
In order to surface mount an ETRX3 series module, we recommend that you use pads which are
1mm wide and 1.2mm high. You must retain the keep-out zone shown in section 12, and ensure
that this keep-out area is free of components, copper tracks and/or copper planes/layers.
You must also ensure that there is no exposed copper on your layout which may contact with the
backside of the ETRX3 series module.
For best RF performance it is required to provide good ground connections to the ground pads of
the module. It is recommended to use multiple vias between each ground pad and a solid ground
plane to minimize inductivity in the ground path.
Figure 9: Recommended Footprint
The land pattern dimensions above serve as a guideline.
We recommend that you use the same pad dimensions for the solder paste screen as you have for
the copper pads. However these sizes and shapes may need to be varied depending on your
soldering processes and your individual production standards. We recommend a paste screen
thickness of 120µm to 150µm.
Although the undersides of the ETRX3 series modules are fully coated, no exposed copper, such
as uncovered through-hole vias, planes or tracks on your board component layer, should be
located below the ETRX3 series module in order to avoid ‘shorts’. All ETRX3 series modules use
a multilayer PCB containing an inner RF shielding ground plane, therefore there is no need to have
an additional copper plane directly under the ETRX3 series module.

14.1 Example carrier board
Since the RF performance of the module with the on board antenna is strongly dependent on the
proper location of the module on its carrier board, Figure 10 shows the reference carrier board
which was used during testing by Telegesis.
Figure 10. Reference Board
For best performance it is recommended to locate the antenna towards the corner of the carrier
board and to respect the recommended keep-out areas as described in section 11.
Finally to provide a good reference ground to the on board antenna, the carrier board should have
a ground plane spanning no less than 40 x 40mm. In many cases a smaller ground plane will
suffice, but degradation in radio performance could be the result.

16 Application Notes
16.1 Safety Precautions
These specifications are intended to preserve the quality assurance of products as individual
components.
Before use, check and evaluate the module’s operation when mounted on your products.
Abide by these specifications when using the products. These products may short-circuit. If
electrical shocks, smoke, fire, and/or accidents involving human life are anticipated when a
short circuit occurs, then provide the following failsafe functions as a minimum:
(1) Ensure the safety of the whole system by installing a protection circuit and a protection
device.
(2) Ensure the safety of the whole system by installing a redundant circuit or another
system to prevent a single fault causing an unsafe status.
16.2 Design Engineering Notes
(1) Heat is the major cause of shortening the life of the modules. Avoid assembly and use
of the target equipment in conditions where the product’s temperature may exceed the
maximum allowable.
(2) Failure to do so may result in degrading of the product’s functions and damage to the
product.
(3) If pulses or other transient loads (a large load applied in a short time) are applied to the
products, before use, check and evaluate their operation when assembled onto your
products.
