Silicon Laboratories ETRX358USB User manual

ETRX358USB
Zigbee & Thread Compatible Radio for IoT Applications
In a USB Stick Form Factor
The
ETRX358USB
is a USB
-
compliant
device
peripheral designed to enable USB host devices
to connect to the Internet of Things over
802.15. Networks. The in-field upgradeable
firmware allows interaction with either ZigBee
®
or THREAD wireless mesh networks.
Featuring the Telegesis™ ETRX3588 wireless
mesh networking module (based on the
EM3588 System-on-Chip (SOC) from Silicon
Labs Inc.), the ETRX358USB takes advantage of
a powerful 32-bit ARM
®
processor with 512 kB
of flash memory and 6 kB of RAM. A link
budget of up to 110 dB is ideal for typical
ZigBee and THREAD applications.
The devices make use of the standard USB
communication device class (CDC) allowing the
best possible native driver support across a
wide range of operating systems.

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

6. OS & Driver support
The USB stick uses the SiLabs
®
CDC Driver to allow for virtual COM port communication over
USB. These drivers are required for proper device enumeration and are available forWindows
(Vista/7/8/10) and Linux from the Silicon Laboratories
®
website:
http://www.silabs.com/product-ETRX358USB

7. Bootloading Firmware
Bootloading allows the user to change or upgrade the device firmware via USB serial using
the XMODEM protocol.
If no application is present on the device, the device will automatically start into bootloader
mode. If the device already contains an AT-Command style application firmware, the
bootloader may be accessed using the AT+BLOAD command.
Once the device is powered, connect to the device using suitable terminal software such as
HyperTerminal, PuTTy or Telegesis Terminal.
•Baud rate: 19,200 baud
•Parity: No
•Flow Control: No
•Data bits: 8
Sending a Carriage Return character (ASCII: 0x0D) will display the bootloader command
prompt. The white LED will also be lit.

Press 1. to begin uploading a valid .ebl binary file. An XMODEM (128 Byte) protocol is required
to upload the file. Once the upload is complete, pressing 2. will run the application. Note that,
if the application does not upload correctly, or the application does not support
bootloading, the bootloader will no longer be accessible.

reasonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
4. Consult the dealer or an experienced radio/TV technician for help.
Modifications not expressly approved by the manufacturer could void the user's authority to
operate the equipment under FCC rules. An FCC declaration of conformity is available
separately from Silicon Labs.
