4 Electrical Specifications

4.1 Power supplies

Only use a mains adaptor that has been certified as a low power source according to IEC60950-1. The power from the USB connection should be restricted in line with the requirements of IEC 60950-

1. PCs approved to IEC 60950-1 will meet this requirement.

Only good quality (vented) alkaline batteries should be used. Ensure they are inserted with the correct polarity. Note that they may restrict the working temperature range of the equipment.

4.2 ZigBee modules

See ETRX357 and ETRX357-LRS Product Manuals

ETRX357 Development Kit

5 Interoperability

Unless otherwise specified the Development kits ships with Telegesis R3xx firmware based on EmberZNet4.x. Please note that the R3xx Telegesis AT-Command line interpreter is based on ZigBee PRO, but most of the functionality is implemented as a private application profile. Interoperability with wireless mesh networking solutions from other manufacturers is only possible when knowing the application profile specification of this device and using the provided transparent commands. If this is a concern please contact us for advice. Telegesis also offer separate firmware specifically developed for Home Automation and Smart Energy applications.

6 Overview

The ETRX357DVK development kit has been designed to allow quick evaluation and prototyping using the ETRX357 ZigBee modules.

This document is intended to describe the hardware and accompanying software of the development kits. To learn more about the usage of the ETRX357 module please refer to the following documents:

 TG-ETRX357-PM-010-xxx: ETRX357 Product manual  TG-ETRX357-LRS-PM-015-xxx: ETRX357-LRS (long range) Product manual  TG-ETRX357USB-PM-014-xxx: ETRX3 USB stick Product manual  TG-ETRXn-R3xx-Commands: AT Style command dictionary for firmware R3xx

All our documents can be found at www.silabs.com/telegesisdocuments. The ETRX357 module is available in four variants:

 ETRX357 – with on-board ceramic antenna and 8dBm output power  ETRX357HR – with Hirose coaxial connector and 8dBm output power  ETRX357-LRS – with on-board ceramic antenna, LNA and 19dBm output power  ETRX357HR-LRS – with Hirose coaxial connector, LNA and 19dBm output power

6.1 The Development Board

Figure 1. The development board

The development board which is part of the development kit hosts a USB to serial bridge as well as voltage regulation circuitry. Furthermore it hosts a reset switch, a bootloader switch, 4 buttons, 2 LEDs and a beeper, all of are connected to the I/Os of the module as described later in this document.

6.2 The carrier board

The carrier board has an ETRX357 module plus two LEDs, and a connector to attach to a Silicon Labs InSight Adaptor for reflashing the firmware. It plugs on to the development board.

6.3 What’s in the ETRX357DVK box?

- 3 x ETRX357DV Development Boards

- 3 x USB cables

- 2 x ETRX357 on carrier boards

- 2 x ETRX357HR on carrier boards

- 2 x ETRX357-LRS on carrier boards

- 2 x ETRX357HR-LRS on carrier boards

- 1 x ETRX3USB USB stick

- 2 x ½-wave antennae

- 2 x ¼-wave antennae

These packages contain everything you need to immediately set up an ETRX357 development platform using the enclosed modules. The ETRX357DVK currently includes an ETRX3USB stick built around an ETRX357 module; earlier kits included the ETRX2USB stick, but the USB drivers and the command set are the same.

7 Setting up the Hardware

In the development kits are all four versions of the module. They can be powered from either a USB hub, the mains (via a suitable power supply) or batteries.

Figure 3. ETRX357-LR Module on Carrierboard plugged on to Devboard

8 ETRX357 pinout

The functions of each of the ETRX357 pins depend on the firmware. When using the Telegesis AT command-based firmware the S-register settings control the configuration of the I/Os. Some of them have a main function and an alternate function, as determined by the value of register S15. Holding pad PA5 low when powering up or resetting the module will cause it to enter the bootloader mode; this operation lies outside the normal firmware so it is independent of the value of S15. As the functions are firmware-dependent and may change between versions, Table 3 should be read in conjunction with the latest R3xx AT Command Manual.

Notes on Table 3 headings Name is the designation of both the ETRX357 pad and the EM357 chip pin. Index can be used to reference the individual pin in various S-registers (see the R3xx AT Command

Manual)

Pad is the module’s pad numbering Default direction indicates whether the pad is normally an input or output Main function and Alternate function indicate the purpose and connection of the pad Default alt fn setting indicates whether the default firmware setting chooses the main or alternate

Notes

{1} The IRQS are always enabled; it is not necessary to activate the alternate function. PB0 is not available for use on an ETRX357-LRS module as it is used internally to control the RF front-end module

{2} The ADCs are normally disabled; it is necessary to activate the alternate function {3} In a development kit, the sensor supply outputs PA2 and PA3 must be high for the sensors to

function {4} On the ETRX357 TX_active is an output which indicates that the RF circuit is transmitting. On

the ETRX357-LRS TX_active is always selected, and is not available as an ordinary I/O because it is connected internally to RF components.

9 The Development Board

9.1 Development Board Interface Description

Figure 4. The development board

Figure 4 shows the location of the connectors described below. Programming Connector: The 10-way programming connector X3 is used to program the

ETRX357 module from a Silicon Labs InSight Adaptor. It is duplicated on the carrier board, and will not normally be fitted in the Development Board.

USB Port: The USB serial port allows connectivity to a PC. This provides access to the command line interface and the bootloader for firmware upgrades, and supplies DC power to the board.

I/O connection: JP1 and JP2 can be used to connect the I/O pins as shown in Table 4. Reference Ground: JP4 is connected to the devboard’s ground plane. It can be used as a reference

point when making measurements on the devboard.

ETRX357 Development Kit

I/O breakout: JP1 and JP2 give access to the I/O on the ETRX357 module. The individual pins are labelled on the

circuit board, and the pin numbering (PA0, PB1 etc) matches that of the EM357 chip inside the module.

Table 4. I/O Connectivity on development board

Flow Control Selection: JP5 is used to connect the RTS and CTS lines used for the flow control to

the host. By default flow control is disabled and the corresponding lines of the module are used as standard I/Os (see the AT command dictionary on how to enable flow control), so the default setting of JP5 does not connect those lines to the host as shown in Figure 5. When flow control is enabled JP5 must be set as shown in Figure 6. Please make sure the jumpers are only set to this configuration when flow control is enabled as otherwise I/Os driving against each other (via a protective resistor) will increase the current consumption.
